Why do Transformers energize and disconnect?

Transformers represent highly inductive loads due to their iron core and, thus, the consequences of energizing and disconnecting a transformer and dealing with the energy stored in its inductance must be considered within a system context.

Why do we need a circuit breaker?

For this reason, protective devices especially circuit breakers [7, 8] are always put in place to isolate any faulty transformer (or substation) to prevent it from sending this abnormal current to the outside circuit which may cause damages to power system equipment and even personnel working around the system [9,10].

What types of circuit breakers are used in electric power transmission & distribution?

This paper presents a review on the applications of various types of circuit breakers (CB) used in electric power transmission and distribution. Circuit breakers are majorly classified under direct current (DC) or alternating current (AC) system.

What triggers a circuit breaker?

The circuit breaker can be triggered by over-voltage, short circuits, and other factors. Circuit breakers are triggered by relays, which sense the changes in parameters of interest and signal the “trip.” Feeder: An electrical conductor that transmits power at distribution voltage from the substation to the individual loads in an area.

Should a solid-state circuit breaker be used to protect a substation?

Using the solid-state circuit breaker (SSCB) on the low-voltage side to protect the substation is favourable compared to implementing the protection on the medium voltage side as the SSCBs do not have to be rated for high overvoltages.
