Ct Differential Wiring Diagram. Referring to figure 6 above input currents defining through the dynamic bus replica the bus differential zone are received by the relay from current transformers. Relay setting calculation ppt.
Electrical abbreviations and acronyms are used very often in the field of electrical industrial. Using six ct in a summing configuration during motor starting the values from the two ct on each phase may not be equal as the ct are not perfectly identical and asymmetrical currents may cause the ct on each phase to have different outputs. As shown in the wiring diagram for the remote tripping function below the delay unit installed outside the circuit breaker may be disabled by an emergency off button to obtain non delayed opening of the circuit breaker.
