Faults In Relays. Check that the control circuit is providing the proper input to the relay. Flashover is dangerous when the current is high. If the contact does not operate (conduct electricity) even though voltage is applied to the coil, it is possible that the relay drive system. Relays that are used frequently can experience mechanical wear and tear, which can cause the contacts to wear out or the actuator to fail. Since relays are such a fundamental part of control system architecture, it must be useful to design simple, effective troubleshooting methods. This often occurs with contacts used with medium and large power. Check for proper voltage, current, and wiring connections. A relay may fail if it is exposed to excessive current or voltage, which can burn out the contacts or damage the coil. Web relay operating principles may be based upon detecting these changes, and identifying the changes with the possibility that a fault may exist inside its assigned zone of protection. We will divide relay operating principles into categories based upon which of these input quantities a particular relay responds. Web the most common relay failures are: Web during the use of the relay, due to various reasons, such as poor product quality, improper use, poor maintenance, etc., various failures often. Flashover is the trouble where discharge between opposing conductors causes a short circuit. Verify that the circuit the relay is connected to is functioning properly. Web excessive current or voltage:
