DCV – Busbar Protection Bay Unit + Capacitor Bank Protection

All protection, control and metering functions required by any Capacitor Bank or Reactance Bay, featuring also complete Bus Differential Bay Unit functionality

DCV systems are designed for Substations where it has been planned or it can be planned in the future the installation of the Bus Differential Protection Unit. The reduction of the cost, due to the integration of the Bank Protection and Differential Position Unit in unique equipment, makes the implementation viable of the Bus Differential Protection Unit in substations where before it was not it.
