CPI terminals are designed for application on circuits (feeders, transformers, motors, etc.) where overcurrent protection for phase-to-phase faults, and ground faults is required.
Overfrequency and underfrequency FGI units are designed to be integrated in systems where a stable frequency value must be achieved. Therefore, a permanent equilibrium between generation and consumption must exist. Overfrequency and underfrequency relays will actuate whenever this equilibrium is altered.
SCI are Synchornism Check Terminals. SCI terminals are designed for synchronism checking between two electrical networks using the state-of-the-art digital technology.
WDI are protective relays against reverse power flow. The equipment incorporates a metering
unit to isolate the generator from the electric circuit, when there is a driving power failure.
