Controlling devices in the transformer and there working and why we are using?

Question

Accepted Answer

Controlling devices in transformers are used to regulate voltage, protect against overloads, and ensure efficient operation.

Controlling devices such as tap changers are used to adjust the voltage ratio of the transformer to maintain a constant output voltage.
Protective devices like relays are used to detect and isolate faults such as overloads, short circuits, and overvoltage conditions.
Monitoring devices like temperature sensors are used to ensure the transformer operates within safe temperature limits.
Automatic voltage regulators (AVRs) are used to stabilize the output voltage of the transformer under varying load conditions.
Control panels with switches, indicators, and alarms are used to manually control and monitor the transformer operation.
