When supply voltage raise beyond or fall rated voltage Proportional DC voltage will change and relay driver IC will command to relay driver to relay and relay will get tripped. 8. Possible additional circuits: Earth fault detection Automatic starting protection … A relay is an electrically operated switch.It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof..

Over voltage protection relay

If over voltage protection is not provided to the power system, there may be high chance of severe damage. A relay, normally connected, which breaks connection when the voltage goes over a threshold. You find this is Voltage Regulators used for Refrigerators and similar devices in countries that have wildly fluctuating power. This is another under / overvoltage protection circuit for designing low- voltage and high voltage protection mechanism to protect the load from damage. This simple electronics circuit uses timers in place of comparator as in the above case as a control mechanism. provide over current protection, directional over current protection (for selectivity in case of multiple parallel lines), under/over voltage protection, breaker failure protection (in case the breaker fails to trip even after receiving the trip command), etc [5].
