AQ-P215 Power monitoring IED

AQ-P215 is a novel power monitoring IED for demanding metering and power monitoring applications. AQ-P215 offers a unique combination of high-accuracy power and energy measurement of class 0.2S, with a dynamic measurement range of up to 250 A (secondary current). Data logging in the flash memory is freely configurable, and the programmable logic and disturbance recorder features allow for a variety of power quality monitoring applications. AQ-P215 communicates using various protocols, including the IEC 61850 substation communication standard.
