The recommended repair for a defective relay.
Answer to Problem 1RQ
The recommended repair for a defective relay is to replace it.
Explanation of Solution
The relay is a switching device and it works to isolate or change the state of an electric circuit from one state to another state. The classification of the relay is based on its function. The some types of relay are listed below.
- Monitoring relay.
- Protective relay.
- Auxiliary relay.
- Regulating relay.
- Reclosing relay.
These different types of relays have different application in different types of fields such as motor control, electrical fuel pump, in controlling large power loads and high voltage. The most important advantage of the relay is that it takes a relatively small amount of power to operate the relay coil. It can be also used to control the motors, lamps, or heaters.
The relay is manufactured by the magnetic coil which is considered to be a throw away device. Due to the parts in the relay, it is not available for the rebuilding or repairing it. Therefore, the recommended repair for the defective relay is to replace it.
Conclusion:
The recommended repair for a defective relay is to replace it.
