Which of the following is NOT a relay protection
Relay protection refers to the use of protective relays, which are automatic devices designed to sense abnormal conditions in electrical circuits and trigger actions to isolate faults. These relays play a crucial role in safeguarding electrical systems, infrastructure, and equipment from malfunctions and electrical problems by detecting issues such as overloads or short circuits . They operate based on various principles, including monitoring the ratio of current and voltage in the protected circuit .
