Description

The AQ-C215 capacitor bank protection device has been specifically designed for the protection of capacitor banks. It includes capacitor bank current unbalance and overload protection in addition to standard overcurrent, earth fault and voltage protections. You can add up to three (3) optional I/O or communication cards into the device for more comprehensive monitoring and control applications. AQ-C215 capacitor bank protection device communicates using various protocols, including the IEC 61850 substation communication standard.

Highlights:

  • Overcurrent, earth fault, and voltage protections.
  • Capacitor bank current unbalance protection with natural unbalance compensation.
  • Capacitor bank overload protection.
  • Harmonic overcurrent protection.
  • Current, voltage, energy and power measurements.
  • Up to 100 disturbance records.
