Protection of parallel feeder The word FEEDER may be referred as the connecting link Hence it is important to protect feeders from faults for. The 750/760 Feeder Protection System is a digital relay intended for the management and primary protection and control of distribution feeders. This easy to use. In solidly grounded systems the residual overcurrent protection can be used on feeders of any length, while in ungrounded or Petersen coil and/or resistance It is a distribution circuit, usually less than 69,000 volts, which carries power from the substation. with the loads. Page 3. Types of feeders. ‡ Radial feeder. Fault between CT and the circuit breaker will not trip the feeder CB and fault current will continue to flow until cleared by back up protection. 3.1.6 Primary For example, a simple ground fault protection relay used at the source end of a transformer-feeder can be treated as unit protection given that the transformer Feeder protection using directional phase and ground overcurrent, voltage and frequency protection and power system metering for one breaker. Buzzer, Bulb, feeder supply and power supply. The automatic overload protection System circuit has a current sensing unit to detect the over current through the.With the increasing loads, voltages and short-circuit duty of distribution substation feeders, distribution overcurrent protection has become more important
