Abnormal operating modes of relay protection

Electromechanical protective relays operate by either, or. Unlike switching type electromechanical with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts.
