It includes capacitor bank current unbalance and overload protection in addition to standard overcurrent, earth fault and voltage protections. The AQ-C215 capacitor bank protection IED is a member of the AQ-200 product line. The hardware and software are modular: the hardware modules are assembled and configured according to the application's I/O requirements, and the software determines the available functions.
