Explanation:
Kick fuses are used across relay coils to prevent relay operation during inrush current of transformers when they are energized. This is because when a transformer is energized, it draws a high amount of current for a short duration of time. This current is known as inrush current.
The inrush current can be as high as 10 times the rated current of the transformer. This current can cause relay operation, which can lead to unnecessary tripping of the circuit breaker. To prevent this, kick fuses are used.
Kick fuses are small fuses that are connected in series with the relay coil. They are designed to blow when there is a sudden surge of current, such as inrush current. When the kick fuse blows, it prevents the relay from operating, thus preventing unnecessary tripping of the circuit breaker.
The kick fuse is designed to blow at a current slightly higher than the rated current of the relay coil. This ensures that the kick fuse only blows during inrush current and not during normal operation of the relay.
In summary, kick fuses are used across relay coils to prevent relay operation during inrush current of transformers when they are energized. They are designed to blow when there is a sudden surge of current, such as inrush current, to prevent unnecessary tripping of the circuit breaker.
