FAQ's

Every equipment we have in our facility works most efficiently at an optimized voltage. At the optimized voltage, equipment will consume less power, heat up less and hence work till its rated life.

All equipment operate for a range of supply voltage. However there is one voltage at which the equipment consumes the rated power. E.g. a 3 star AC will meets its specified EER (energy efficiency ratio) at 230V. If the voltage is even 12% higher then it only performs at an EER (energy efficiency ratio) of a 1 star AC. With Automatic voltage optimization you can automatically learn and apply the optimal voltages thus ensuring that the 3 star AC works at the rated 3 star performance and hence save energy

1. POWEReasy Smart Optimizers uses Machine Learning to determine the optimal voltage and save energy automatically whereas Servo stabilizers have a preselected voltage output.
2. POWEReasy Smart Optimizers are 5X times smaller than a servo stabilizer.
3. POWEReasy Smart Optimizers are is 99% efficient whereas servo stabilizers are 96% efficient.

Homes and offices have a mixed load comprising of lighting, AC, electronics and heating. Further the consumption of these devices varies with external factors such as temperature, humidity, occupancy, etc. In consultation with Central Power Research Institute (CPRI) we have devised a methodology to calculate the energy saving in a short time duration. First all airconditioning and heating sytems are kept on thermostat control to achieve a controlled output. Now, in the first 1 hour duration the energy consumption is measured with the system bypassed and in the next 1 hour with the system with the Optimzer operational. The difference in energy consumption can be used to baseline the savings expected at site.

When an AC thermostat is off, the compressor is continuosly ON and hence fully loaded. Under full load condition,optimizing the voltage does not have a significant impact on energy consumption. Under such condition the optimizer will demonstrate only marginal savings.

Energy consumption varies significantly based on temperature, humidiity, occupancy and time of operation. Seasonal trends alone can increase / decrease billing by 50%. Since the opportunity for energy savings through automatic voltage optimization lies in the 8-25% range the consumption variations can often mislead one in to incorrectly estimating the energy savings

We provide a toggle switch to put the system in bypass and back in POWEReasy Optimizer mode. It is kept inside the system cabinet to avoid mishandling by unauthorized person.

POWEReasy works on the principles of automatic voltage optimization. It enables energy savings when the supplied voltage is sub-optimal for the loads being operated. As a rule of thumb sites with voltage variation exceeding 8% and equipment that are not operating at full loads are good candidates for energy savings. Motors that are loaded greater than 85% of its rating have lower opportunity for energy saving.

POWEReasy Optimizers can both increase the voltage when its low and reduce voltage when it is high. It studies a 6% range to evaluate the optimal voltage for a set of loads and applies it automatically

POWEReasy trips the systems for 12 unique electrical issues that are not covered by typical voltage stabilization devices e.g. high earth voltage, neutral loss, voltage harmonics, etc.

The facility can have any power rating. However, we look for the individual sub-DBs or loads to be less than 30KVA

For small facilities it is installed at the mains for larger facilities we install POWEReasy at sub-DBs

The main feature of POWEReasy system is to protect facility from electrical fault/accident which lead to fire. If we install large system (Only one system) for entire facility then there may be a possibility of tripping system due to electrical issue in minor load/Equipment which cause total power cut off. To avoid this we always suggest to install POWEReasy across DBs.

A typical voltage optimization techniology only provide a fixed drop in voltage. POWEReasy Smart Optimizers is the only system that uses machine learning to learng and then to adjust the output voltage based on load requirements automatically

There are always continous voltage fluctuations at the input it will adjust the output to an optimal voltage and hence save energy

POWEReasy Optimizers cannot add or eliminate harmonics. It will however report both current and voltage harmonics. If the voltage harmonics are outside the acceptable ranges of IEEE 519 it will also disconnect the power supply to protect equipments downstream

From 185V to 270V Phase to Neutral

1. Complete protection from all electrical problems
2. Compact size
3. Highest efficiency of any power conversion system
4. Software to optimize voltage and saves energy
5. Noise free operation

Our systems offer a 18-24 month payback period. If you want a detailed calculation we need the electricity bills

Optimum does not need a reference mathematically speaking.

We measure voltages and currents and derive all required paramters from these measurements.

We have seen errors of up to 3%

The negative point is that it still requires installation and maintanance.

It works for 20% overload for 30 minutes

Ideally it would be better to install on every individual load. But since it is not ecomonically possible we choose a common loads across all DBs , club them together and propose a POWEReasy for that load

Neutral is normally required at the input of the System. Hence neutral can be taken from the lighting load. No problem if neutral is not available at the output. Neutral to Earth voltage is one of the key parameter of electrical protection

Dynamic

It is three phase independently controlled

Both provided

It will boost voltage as required

POWEReasy system is installed in line with specific DBs. The load has to be distributed across the POWEReasy devices. The maximum POWEReasy rating in 3 phase is 30KVA (40 Amperes per phase). You can share a site and we can give our version of the SLD after a survey.

Using estimates for VIcos(phi) work well for linear loads. In the case of linear loads voltage has a quadratic relationship with power. But in reality, the vast majority of loads are becoming electronic. They are non-linear and observe fairly complex relationships to the input voltage. The machine learning we employ hence observes and collects empirical data to identify the voltages in a narrow +/-6% band to identify the voltage at which the facility is operating most efficiently. This is job prime for automation and you ought to use machines where the problem is not addressable by humans.

If you choose to install the POWEReasy Smart DB with optimizer you do not need to install any additional stabilizer or surge protection devices (up to Type II).

85% of fires in buildings are classified as short circuits. Even with several layers of short circuit protection installed in our buildings we are still at risk. There are 12 risks to electrical fires including arc faults, neutral fault, reversal of phases, voltage harmonics, phase loss, surges, earth voltage issues, current harmonics and current unbalance. Our exisiting DBs only protect for 3 viz are short circuit, overload and earth leakage currents. With POWEReasy you enable complete coverage of these 12 electrical faults and hence protect your site from electrical fires

POWEReasy Smart DBs are a new innovation and it is common that not everyone has learnt about it yet.

Yes, POWEReasy Smart DBs can also be configured to have wifi connectivity to send all your data to the cloud, which will inturn alert you via SMS

POWEReasy Smart DB is easy to install. However we request your local electrician to go through our training and certification process to help understand and fix electrical faults

You can opt for the DB upgrade modules such as the Smart Protection Unit or Smart Optimizer

Electrical faults appear from the source or the load. If the question is pertaining to load related faults then POWEReasy senses all currents supplied to sub DBs and loads downstream to a DB. By definition it has electrical parameters it can measure for the downstream loads. It will report the fault based on the exact nature of the fault, phase and load levels it occurs at, which is sufficient to narrow down the electrical fault to the root cause. If you have the financial resources you can choose to install a device for every outlet.

POWEReasy Smart DBs cannot add or eliminate harmonics. It will however report both current and voltage harmonics. If the voltage harmonics are outside the acceptable ranges of IEEE 519 it will also disconnect the power supply to protect equipments downstream

Arcing is one of the most complex electrical phenomena to measure. It is no surprise that our electro mechanical switchgears is not able to identify these problem. Arcing creates braodbrand noise that needs to be sensed, via specialized electronics circuits. This is then filtered and compared using a pattern matching algorithm in our microcontrollers. The microcontroller classifies the fault arc from other arcing events such as arcs from motor brushes, contactors, etc.
