Relay Failure. during the use of the relay, due to various reasons, such as poor product quality, improper use, poor maintenance, etc., various failures often occur. Flashover is the trouble where discharge between opposing conductors causes a short circuit. in modern relays, communication failure refers to the inability of the relay to properly communicate with other. In this article, we will discuss the main causes of failure in mechanical relays, as well as look into simple methods of testing relays using common hand tools. A relay may fail if it is exposed to excessive current or voltage, which can burn out the contacts or damage the coil. used relays (that have been installed or have switched any load current) cannot be reliably tested for contact resistance after installation or use due to the pitting that results from. april 07, 2020 by david peterson. Welding, locking or gluing make it difficult to open contacts. This often occurs with contacts used with medium and large power. excessive current or voltage: the most common relay failures are: If the contact does not operate (conduct electricity) even though voltage is applied to the coil, it is possible that the relay drive system (coil) is. Since relays are such a fundamental part of control system architecture, it must be useful to design simple, effective troubleshooting methods. Flashover is dangerous when the current is high.
