AQ-E215 Energy management IED

AQ-E215 is an energy management IED that integrates kWh metering with billing-level accuracy and the fault location functionality in one single equipment. The combination of highly accurate measurement technology and fault detection algorithms allows AQ-E215 to be applied for various applications: volt/VAR optimization, power loss tracking, and the reduction of power outages via accurate fault locating. AQ-E215 communicates to SCADA and DMS systems with various standard protocols, which makes your power distribution grids smarter while the cost remains affordable.
