Question 1

What applications require a three phase smart meter?

Accepted Answer

Three phase meters are needed for industrial machinery, large commercial spaces, lifts, pumps, common area lighting in large housing societies, and any load above 7.5 kW that requires three phase power supply.

Question 2

What is the accuracy class of the PES-20-SS?

Accepted Answer

The PES-20-SS meets Class 1 accuracy as per BIS IS:13779, meaning the measurement error is within ±1 % across the full load range — suitable for commercial and industrial billing where accuracy is critical. But our BIS test results show that our smart meters have less than 0.1% accuracy.

Question 3

Can the PES-20-SS detect power theft?

Accepted Answer

Yes. The meter logs current imbalance, neutral disturbance, and reverse current events — all common tampering signatures. Tamper alerts are sent to the AMC dashboard in real time so corrective action can be taken immediately.

Question 4

Does the PES-20-SS support maximum demand monitoring?

Accepted Answer

Yes. The meter records Maximum Demand (MD) in 5-minute intervals, enabling industries and large societies to monitor peak demand and take corrective action to avoid costly MD penalties from the utility.
