HOW TO RESOLVE FAULTS

Why did POWEReasy trip?

Your site has observed an event of an extremely high current. These high currents can lead to overheating and fires. POWEReasy has tripped to protect your facility from fires.

When do you need to fix this and why?

Short Circuit fault needs to be fixed immediately or it would lead to a fire.

What should you do next?

• Start the POWEReasy system after switching off all the loads. This can be done by putting all the MCBs in the distribution Box in the OFF position.
• If system MCB trips again then the issue is with the POWEReasy system MCB, please call the POWEReasy installer to have this resolved.
• If the system MCB does not trip then switch on your loads one by one. Identify the load where the system trips. This is a faulty load.
  • Advice for basic users: Please turn ON only one load MCB at a time i.e. during checking of the next load MCB please turn OFF previous load MCB.
  • Advice for expert users: For advanced analysis you can note down load current as you switch on each load MCB.
• In case you have a faulty device the faulty device can be kept off till it is repaired by an appropriate serviceman.
• Repeat this step to identify all faulty loads.
• Once you have the list of faulty MCBs you can call your electrician to check the wiring of each faulty MCB
• If there is no evident fault in the wiring the short circuit / overload could be appearing from devices connected. An electrician can help identify any obvious damage, poor connections or malfunctioning. For specialized equipment such as ACs, electronics, etc. you would have to call the appropriate repairman
• If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Tips for the Electrician

• Within our dashboard you can refer to the system analytics to identify when and for how long were you observing the high currents.
• High load currents are not always observed from one device. Overload ing by switching ON multiple loads can cause the main MCB to trip over within few minutes to 10s of minutes. Having a list of all loads and verifying that the full load current doesn’t exceed MCB ratings is advisable if an overload fault has been observed

Why did POWEReasy trip?

Your site has observed an extreme high voltage event. IEEE1159 recommends fast protection in case of voltages that are greater than 276V. These overvoltage conditions can lead to damaging expensive equipment and also fires.

When do you need to fix this and why?

Critical Overvoltage fault needs to be fixed immediately or it would damage your equipment and even lead to a fire.

What should you do next?

• Do not use the incoming electrical supply till the voltage levels are in acceptable range.
• If you have a backup supply such as a DG, UPS or inverter use that. The inconvenience caused is a small one as compared to having a critical event that may lead to asset loss or even fires.
• You can check every 30 min if the voltage is in acceptable range by switching ON the main MCB. If it does not trip and goes through an initialization process the supply is in usable range

Tips for the Electrician

• If the location is seeing the problem repeatedly, a suitable voltage regulation device can be recommended. You can opt for the POWEReasy Voltage optimizer that comes with an 18% energy savings validation by CPRI.

Why did POWEReasy trip?

Your site has observed an extreme low voltage event. IEEE1159 recommends fast protection in case of voltages that are less than 184V. These under voltage conditions can lead to damaging expensive equipment and also fires.

When do you need to fix this and why?

Critical under voltage fault needs to be fixed immediately or it would damage your equipment and even lead to a fire.

What should you do next?

• Do not use the incoming electrical supply till the voltage levels are in acceptable range.
• If you have a backup supply such as a DG, UPS or inverter use that. The inconvenience caused is a small one as compared to having a critical event that may lead to asset loss or even fires.
• You can check every 30 min if the voltage is in acceptable range by switching ON the main MCB. If it does not trip and goes through an initialization process the supply is in usable range

Tips for the Electrician

• If the user is seeing the problem repeatedly, a suitable voltage regulation device can be recommended. You can opt for the POWEReasy Voltage optimizer that comes with an 18% energy savings validation by CPRI.

Why did POWEReasy trip?

Your site has experienced a loss of power in one of the three phases. Such conditions are extremely critical for 3 phase loads. Motors can overheat and burn. Even if there are single phase loads the sudden loss and reappearance of power can damage your critical equipment.

When do you need to fix this and why?

Phase loss fault needs to be fixed immediately or it would damage your three phase equipment and even lead to a fire. If you do not have three phase equipment you could use supply in 2 available phases. Do note that when the supply on the third phase returns it might come with a Surge which could damage your equipment if POWEReasy is bypassed.

What should you do next?

• Do not use the incoming electrical supply till the voltage levels are in acceptable range.
• If you have a backup supply such as a DG, UPS or inverter use that. The inconvenience caused is a small one as compared to having a critical event that may lead to asset loss or even fires.
• You can check every 30 min if the voltage is in acceptable range by switching ON the main MCB. If it does not trip and goes through an initialization process the supply is in usable range
• To further debug the fault, check that the supply voltage on the phase indicated. This can be verified by checking the supply voltage at the electricity meter. If the voltage is less than 120V you should report this to your electricity supplier immediately for them to have it fixed.
• If the supply at the meter is above 120V then then there is an issue with facilities internal electrical wiring or protection systems. Ask your electrician to check the supply voltage to each MCB / isolator and POWEReasy system MCB to identify where there is the loss of supply or connection. If there is a loss of supply at any MCB/isolator you need to verify the following at that point
  • Check the wiring for that particular phase. If it is loose, correct it.
  • Check if the MCB / isolator / fuse are functional.
  • Check for continuity of the wires with a tester.

Tips for the Electrician

• In case a client is ONLY using single phase loads they can operate the system for its two available phases. The tripping mechanism can be temporarily bypassed. However, there is a risk of other faults such as surges, neutral loss or arcing that would also be temporarily deactivated.
• If the user is seeing the problem repeatedly, suitable back up solutions can be recommended
• If supply is available to neighboring facilities in all three phases, a review of the site wiring to identify the location of fault is necessary

Why did POWEReasy trip?

Your site has experienced a loss of neutral. Such conditions are extremely critical in any facility and it is one of the most critically identifiable reasons for electrical fires.

When do you need to fix this and why?

Neutral loss fault needs to be fixed immediately or it would damage your equipment and even lead to a fire. The neutral loss event could be from your electricity supplier or internal to your facility.

What should you do next?

• Switch off all your loads and call your electrician immediately. Do not use the incoming electrical supply till problem is identified and resolved.
  • Advice to electricians: identify the neutral fault issue follow the steps below
  • If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Tips for the Electrician

• Neutral or earth wires could be open, burn out, eaten by rodents or disconnected.
• Neutral loss is not easily to identifiable using the standard means of checking supply with testers and voltmeters.
• To identify the location of the fault use the following steps
  • Switch OFF the mains supply at the energy meter
  • Disconnect the neutral and earthing wire from the output side of the energy meter o Short the input neutral and the earthing wire at the POWEReasy system
  • Check continuity between the neutral and earthing wire disconnected from the energy meter.
  • Switch OFF the mains supply at the energy meter
  • If continuity is met then the issue is from the electrical supplier, they must be informed to have the problem fixed. If there is no continuity then the fault is within the facility.
  • The exact location of the fault can be identified by doing the same analysis described above at different points from the energy meter to smaller branches of the circuit that are connected before the POWEReasy system
• If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Why did POWEReasy trip?

Your site has observed a high earth voltage event. IEEE1159 recommends that the earth voltage must be within 3V. The POWEReasy system warns at 3V but starts to disconnect supply when its higher than 7V. These overvoltage conditions can lead to damaging expensive equipment and electrocution.

When do you need to fix this and why?

Critical Earth Voltage fault needs to be fixed immediately or it would damage your equipment and even lead to electrocution.

What should you do next?

• Start the POWEReasy system after switching off all the loads. This can be done by putting all the MCBs in the distribution Box in the OFF position.
• Restart the POWEReasy system and check if the system trips check for the following problems
  • If the system trip, call the electrician to identify a critical fault in the earthing. The issue could be due to poor connection of earth and neutral wire from the transformer to the system. Electrician must check for loose connections, broken wires / busbars, undersized cables, damaged insulation, exposed wires, etc
• On restarting if the system does not trip
  • If the System does not trip and Earth Voltage Warning is present it might need correction to earthing Pit. You can try to add water to the earth pit and if that does not solve the problem you might want to call an earthing expert.
  • If the System does not trip and Earth Voltage is less than 1V then turn on loads one by one to identify loads that are faulty. Please turn ON only one load MCB at a time i.e. During checking of the next load MCB please turn OFF previous load MCB.
  • Once you have the list of faulty MCBs you can call your electrician to check the wiring of each faulty MCB.
  • If there is no evidence of fault in the wiring the high earth voltage could be appearing from the devices connected. An electrician can help identify any obvious damage, poor connections or malfunctioning. For specialized equipment such as ACs, electronics, etc you would have to call the appropriate repairman
  • If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Tips for the Electrician

• Poor connection to earth and neutral can be cause of high earth voltages
• Loose connections and exposed wires can also lead to high earth voltages
• You can use the socket testers

Tips for Expert User

• For advanced analysis you can note down load current and earth leakage currents and earth voltage as you switch on each load MCB. Further analysis of this data will tell you if the fault is on the neutral wire or earth wire
• High earth voltage could be observed if there is high current unbalance. This indicates high resistance on the neutral wire observed from a poor connection, undersize wires, or damaged wires / busbars.
• You can use the Top Risk or Alerts>Issues section to find out if the high earth voltage is due to switching ON or OFF of specific loads. This should narrow down the area where you need to identify the earth voltage issue

Why did POWEReasy trip?

Your site has observed a high earth leakage current event. IS12640 that 30mA is unsafe for single phase operation and 100mA is unsafe for 3 phase operation. The POWEReasy system warns at 20mA earth leakage current but starts to disconnect supply when it’s higher than 100mA.

When do you need to fix this and why?

Critical earth leakage fault needs to be fixed immediately or it would lead to electrocution and fires.

What should you do next?

• Start the POWEReasy system after switching off all the loads. This can be done by putting all the MCBs in the distribution Box in the OFF position. Switch off all loads
• Restart the POWEReasy system and check if the system trips call the electrician to identify one of the problems below:
  • Input and output neutral could be interchanged.
  • Input and output neutral wires could be joint / shorted.
  • Earth and input neutral wire could be interchanged.
  • Earth and output neutral wire could be interchanged.
• If the System does not trip and Earth leakage is low then turn on loads one by one to identify loads/circuit that is faulty. If the MCB trips during this process you have detected a faulty load. Repeat this step to identify all faulty loads.
• Once you have the list of faulty MCBs you can call your electrician to check the wiring of each faulty MCB.
• If there is no evidence of faulty wiring the high earth leakage could be appearing from devices connected. An electrician can help identify any obvious damage, poor connections or malfunctioning. For specialized equipment such as ACs, electronics, etc you would have to call the appropriate repairman
• If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Tips for the Electrician

• Poor connection to earth and neutral can be cause of high earth leakage
• Interchanging of neutral and earth wires can also lead to high earth leakage
• Looping of neutral wires or using neutral wires from a different circuit can also lead to earth leakage

Tips for Expert User

• For advanced analysis you can note down load current and earth leakage currents as you switch on each load MCB.
• High earth leakage currents are observed if phase and neutral wires are not used from the same panel. By measuring the phase and neutral current at system MCB as you switch on loads you can find the 'foreign' phase OR neutral wire by measuring individual neutral and phase wire currents with a clamp meter.
• You can use the Top Risk or Alerts>Issues section to find out if the high earth leakage is due to switching ON or OFF of specific loads. This should narrow down the area where you need to identify the earth leakage current issue

Why did POWEReasy trip?

During startup the POWEReasy device has identified that the sequence of Phases has been interchanged. This could happen from the supplier directly and is harmful to the operation of motors.

When do you need to fix this and why?

Phase reversal fault needs to be fixed immediately or it would damage your equipment and even lead to a fire.

What should you do next?

• If the phase reversal issue has occurred at the time of installation it must be solved by the installer by correctly configuring the supply phase convention:
  • Open the system
  • Identify the jumper in the correct location as shown in figure and remove it.
  • Now you can turn on the system.
• If the phase reversal issue is observed after a few days of installation
  • Inform your electricity supplier immediately
  • Do not use the incoming electrical supply till the phases are back in the correct sequence. Some of your three phase loads might not start or in the worst case may start, overheat and lead to operational losses and fires
  • If you have a backup supply such as a DG, UPS or inverter use that
  • You can check every 30 min if the voltage is in acceptable range by switching ON the main MCB. If it does not trip and goes through an initialization process the supply is in the correct sequence

Tips for the Electrician

• If the user is seeing the problem repeatedly, a change over switch with phase corrector can be recommended
• If there are critical tasks that need to function you can reverse the input phase temporarily by interchanging the R and Y wires at the input of the POWEReasy system

• If the system does not trip then turn on loads one by one to identify the circuit that is faulty.
• Repeat this step to identify all faulty loads.
• Once you have the list of faulty MCBs you can call your electrician to check the wiring of each faulty MCB.
• If there is no evident fault in the wiring the arcing could be appearing from devices connected. An electrician can help identify any obvious damage, poor connections or malfunctioning. For specialized equipment such as ACs, electronics, etc. you would have to call the appropriate repairman
• If the issue is still not solved contact the POWEReasy service support team to schedule a visit from our team of POWEReasy certified electrical experts

Tips for the Electrician

• Arc faults occur due to exposed wires or loose connections. These wires can be concealed in the wall, could be outside your premises or hidden from plane sight.
  • To identify the exact location of an exposed wire a methodical approach towards analysis of the circuit is required. A trained team from Jhaveri Power Labs can help here.

Tips for Expert Users

• Arcing could be observed due to insulation damage in concealed and out of reach wiring. Following a circuit wise analysis of the electrical network can help identify this issue. POWEReasy certified electrical experts can help you in this process.
• Arcing events can be sometimes observed in induction heaters and small motors of drills or vacuum cleaners. If the device cannot be corrected consult a POWEReasy certified electrical expert for using appropriate filters

Why did POWEReasy trip?

Your site has observed an extremely high voltage harmonics. IEEE519-2014 recommends voltage harmonics to be constrained within 8%. Voltage harmonics can lead to malfunctioning electronic devices, humming in electromagnetic devices and overheating in transformers.

When do you need to fix this and why?

Critical Voltage Harmonics needs to be fixed immediately or it would damage your equipment

What should you do next?

• On restarting the system MCB check for voltage harmonics warnings. If the voltage harmonics are over 8% for over 5 minutes the system would trip again
• Switch of all sensitive loads. You should also report this to your electrical supplier as these are issues that they must correct this issue
• You can choose to operate non critical loads by disabling the tripping mechanism of POWEReasy by calling a local electrician.
• If you have a backup supply such as a DG, UPS or inverter use that
• You can check every 30 min if the voltage is in acceptable range by switching ON the main MCB. If it does not trip and goes through an initialization process the supply is in usable range
• Voltage harmonics can occur from overloading transformers or loose connections so you can have these checked by your local electrician

Tips for the Electrician

• If the user is seeing the problem repeatedly, a double conversion UPS could be recommended
• Voltage harmonics could be due to poorly maintained transformer
• Poor earthing can also have an impact on voltage harmonics
• Extremely high current harmonics can also lead to voltage harmonics.
• For other options for harmonic mitigation a detailed audit by a POWEReasy certified expert would be necessary.

Why did POWEReasy trip?

Your site has observed an extremely high voltage Surge. UL1499 recommends a Type 3 surge protection at the load points. POWEReasy is already equipped with such protection. However in case of Surges observed for longer durations also known as instantaneous and momentary swells POWEReasy cuts off supply as a precautionary measure.

When do you need to fix this and why?

Voltage Surge fault needs to be addressed immediately or it would damage your equipment and even lead to a fire.

What should you do next?

• Start the POWEReasy system after switching off all the loads. This can be done by putting all the MCBs in the distribution Box in the OFF position. Switch off all loads. Restart the POWEReasy system and check if the system trips or is OK
• Voltage surges are short duration events. Once you restart the system MCB and it trips there is a critical fault from the electrical supplier. Inform the electricity supplier for them to correct the fault
• You can choose to operate non critical loads by disabling the tripping mechanism of POWEReasy by calling a local electrician.
• You can shift to back up supply such as DG, UPS or inverter. The inconvenience caused is a small one as compared to having a critical event. Once you get confirmation from the electricity supplier that the issue is fixed you can turn on the supply

Tips for the Electrician

• If the user is seeing the problem repeatedly, a Type I/II surge protector might have to be installed at the main incomer for the facility.
