Determining the Sensitivity of Relay Protection
Sensitivity Test: Confirms that the protection works properly for internal defects in the protected zone. If the CTs are properly connected, there should be no operating current at. The relay protection sensitivity is one of the determined factors in the power system, however, it is often overlooked in current distribution network (DN) planning. The relay protection sensitivity can be decreased to below the minimum values, failing to meet the requirements for electrical. An assessment of sensitivity of the measuring elements of relay protection was performed. Clamp Meter – used for non-intrusive current measuring. Unit protection procedures that includes differential protection are based. Demetrios Tzi uvaras Schweitzer Engineering Laboratories, or the complete history of this paper, refer to the next page. phase overcurrent relays in addition to one residual-ground voltage breaker trip circuits and ground switches. It is the ability of the relay system to operate under the pre-determined.
