Action time of relay protection device

Action time of relay protection device

The need to act quickly to protect circuits and equipment often requires protective relays to respond and trip a breaker within a few thousandths of a second. In some instances these clearance times are prescribed in legislation or operating rules. Core idea: Protective relays monitor electrical quantities and command protective devices to isolate faults or abnormal operating conditions. Action time, as an important indicator to measure the response speed of relay protection devices, reflects the duration from the. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. Inverse time delay, on the other hand, depends on the current magnitude so, the higher the current, the shorter the delay. [pdf]
