Single Phase Energy Meter has high energy resolution and reduces energy loss due to power outage. The Meter is anti tamper and has features such as current reversal, earth tampers phase/ neutral cut, neutral loop, pure/ chopped dc injection in phase/ neural circuit. The Meter measures active energy, apparent energy, maximum demand KW, maximum demand KVA, RMS voltage, true RMS phase current, true RMS neutral current, instantaneous signed power factor, instantaneous frequency and instantaneous load. The Single Phase Energy Meter has active pulse outputs and visual tamper indications and can store 35 days load profile with KWH, average voltage and average current, for the integration period for integration period of 30 minutes.
