In this article we will discuss about the sources of over-voltage and its protection. Sources of Over-Voltage: Transients are disturbances that occur for a very short duration (less than a cycle) and the electrical circuit is quickly restored to original operation provided no damage has occurred due to the transient. An electrical transient is a cause-and-effect phenomenon. For transients …
