The relay protection with the highest sensitivity is
The smaller the volt-ampere input required to cause relay operation. Thus, a I VA relay is more sensitive than a 3 VA relay. It is desirablethat relay system should be setusitive so that it operates with low values of volt-ampere. The protected zone is the part of the network in which faults cause the protection function to operate. Definite time delay means that the protection operate time dose not change or depend on the. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. The selection and applications of. One of the main requirements to relay protection is the sensitivity requirement, which implies consistent tripping during the short circuit (s c) events in the protected zone. Various combinations of "operate torque" and "restraint torque" can be produced in the relay. Sensitivity of a relay means its capacity to operate reliably under the actual conditions that produce. The relays detect the abnormal conditions in the electrical circuits by constantly measuring the electrical quantities which are different under normal and tault conditions The electrical quantities which may change under fault conditions are voltage, current, frequency and phase angle. -
