Transformer protection refers to the measures taken to prevent damage to transformers from faults or abnormal operating conditions.
Transformer protection devices include overcurrent relays, differential relays, and Buchholz relays.
Overcurrent relays protect against overloads and short circuits.
Differential relays compare the current entering and leaving the transformer to detect internal faults.

Squirrel cage induction motors have a simple and robust design, while slip ring induction motors have additional components for controlling speed and torque.
Squirrel cage induction motors have a rotor with short-circuited conductors, while slip ring induction motors have a rotor with external resistors or brushes.
Squirrel cage motors are commonly used in applications where constant speed is required, such as fans and p...
