IDV differential protection relays are designed to provide reliable and secure protection both for internal faults and faults ocurring within the CTs zone in power transformers, autotransformers, reactances and rotating machines.
BCV relays incorporate protection, control and metering functions for capacitor bank and reactance applications combining the specific protection functions with complete bay protection in a single IED.
DCV relays feature the same functionally as the BCV models with an additional module for distributed bus differential protection. The DCV relays can be integrated as bay units into the bus differential central unit model DBC.
6RTV units integrated power transformer voltage regulation via tap changer control, maintaining the voltage within constant. It is of a application when voltage must be kept within constant values with the transformer in operation.
RTN provides power transformer voltage regulation via load tap changer control. The RTN hardware and software platform is comparable to the protection relays in this family, providing easy integration in the substation protection and control system.
BCD systems include all the functions needed for capacitor bank protection. The various models allow adapting to different architectures and topologies.
