AQ-P215 Power monitoring device


AQ-P215 is a novel power monitoring device for demanding metering and power monitoring applications. AQ-P215 offers a unique combination: the high-accuracy power and energy measurement of up to 0.2 % is paired 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.


  • Accuracy class of up to 0.2 %.
  • Patented frequency-independent measurement.
  • The frequency-tracking algorithm guarantees measurement accuracy at 6–75 Hz.
  • Power quality analysis (harmonics, THD and disturbance recording).
  • Ultra-fast Modbus/TCP communication (5 ms update interval).
  • A powerful disturbance recorder with a sampling rate of up to 64 samples per cycle.
  • A dynamic measuring range of up to 250 A (secondary current) – effective disturbance recording when coupled to a protection current transformer.
  • A calendar feature with automatic adjustments for daylight savings time and leap years.
  • Programmable logic functions.
  • An extensive data logging capability.
