Energy and power quality measurements for smart grid deployments.
The Model EM920 eXpertmeter™ is an advanced energy and power quality meter that exceeds Class 0.2S class revenue billing requirement. It provides long term memory for load & trend profiles, and includes advanced power quality analysis to detect and record waveform events and fault currents harmful to power systems.
The EM920 eXpertmeter™ is MET certified.
The EM920 eXpertmeter™ Series is used in electric utility inter-ties, any electrical substation where precise information is required for planning purposes, and monitoring primary customers on the service entrance to provide a higher service in quality of power.
- Install at legacy substations where little to no information is currently provided. Just replace existing socket meter and instantly provide information previously unattainable.
- Long term monitoring and storing capabilities allow for many months of information storage. Record Time Of Use (TOU), load profile, Min/Max, custom reports etc. – essential information used for planning and maintenance engineers.
- Multiple simultaneous communications allow communication via MODBUS, DNP3.0, and MV90 while retrieving power quality events such as SAG/SWELL and transient detections.
- View Harmonic conditions locally to determine the cause of problems by utilising its unique “Directional” Harmonics Power flow.
- View real time Oscillography and determine quality of power.
