Relay protection is primarily the principle of using changes in electrical quantities (current, voltage, power, frequency, etc.) that constitute relay protection actions when short circuits or abnormal conditions occur in components of the power system, as well as other physical quantities, such as the large amount of gas and the increase in oil flow rate or oil pressure strength that accompanies a fault in a transformer tank. In most cases, regardless of which physical quantity is reacted to, the relay protection device consists of a measuring part (and a constant value adjustment part), a logic part and an execution part.
