Applications

The REV615 is designed for primary protection of H-bridge, double Y-type and single Y-type connected capacitor banks and feeder cables.

In addition, the REV615 can be used to protect harmonic filter circuits when the harmonic component is not higher than the 11th.

The REV615 is available in two standard configurations, both of which provide three-phase overload protection, current-based unbalance protection (natural unbalance compensation), and current-based capacitor bank switching resonance protection.

The overload protection includes an integrated undercurrent function that detects the disconnection of the capacitor bank and inhibits the closing of the circuit breaker when the capacitor bank is partially charged.

Three-phase thermal overload protection is available for reactors and resistors in harmonic filter circuits.

The REV615 also provides non-directional overcurrent and ground fault protection for capacitor banks and their feeder cables.

Standard configuration B also provides directional ground fault, residual voltage, voltage unbalance, and over- and under-voltage protection.

Standard configuration A is pre-configured for H-bridge connected capacitor banks with three-phase unbalance protection.

Standard configuration B is pre-configured for capacitor banks with double Y-bridge connection and has single current unbalance protection.

The standard configurations can be customized to meet the requirements of the application with the IEC 61850-compliant protection and control IED manager PCM600.
