In radial feeder, the power flows in one direction only, which is from source to load. This type of feeders can easily be protected by using either definite time relays or inverse time relays.
The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily. The functional requirements of the relay:.
Employ the SEL-TMU for remote data acquisition in substations with Time-Domain Link (TiDL®) technology systems. It can share data with up to four TiDL relays. Provide high-speed transformer diferentia.
The development of the relay protection based on open architecture is a relevant direction of electrical and electronic engineering. The paper presents the problem of the modern microprocessor-based relay prote.
