This document summarizes a presentation on radial feeder protection concepts. It discusses the components of a radial feeder distribution system and protective schemes to avoid malfunctions. It then describes the setup of a radial feeder protection panel that students can use to learn fundamentals of protection. Electromechanical relays, wiring diagrams, and photos of the physical panel are shown. The conclusion discusses how faults can be protected against and how the hands-on project helps students understand basic protection terminology.

- 3. ABSTRACT This paper represents the work done in the field of distribution system. Power distribution systems are the portion of electrical systems that connects consumers to the source of bulk power. Distribution System consists of several substations which includes one or more feeders. Radial feeder system consists of having only one path for power to flow from the source to each consumer. The protective systems of radial feeder are essential for the same. In this paper we understand various protective schemes to avoid malfunctioning of electromechanical relay). Through this paper we are preparing operation of radial feeder protection as real substation environment. Through this protection concept, the students, in addition to getting familiar with the fundamentals of protection, learned how different protection schemes are wired and how they operate in a real power system. 04/22/2016 3 A Review of Radial Feeder Protection Concept

Simple working Methodology of Protection Circuit Abbreviations Bus Charged bus bar CB Circuit Breaker Trip Coil Tripping coil of CB Trip Contact NC contact of Protective Relay Relay Protective Relay CT Current Transformer Feeder Power Distribution feeder 04/22/2016 8 A Review of Radial Feeder Protection Concept
- 9. Simple working Methodology of Protection • Voltage is flowing from Bus bar to Feeder. In between the circuit breaker is installed. • the tripping coil of CB is charged by external supply. • Here this external voltage is generating from battery. And the voltage is flowing from NC contact of Protective relay to tripping coil of circuit breaker. That means this NC contact of relay is tripping contact for Circuit breaker. • The CT (current Transformer) is measuring the actual current flowing from feeder. • When the current will rise grater then sated at relay, the relay will trip and supply is going to the CB coil will trip also. • And finally the circuit breaker will trip also. 04/22/2016 9 A Review of Radial Feeder Protection Concept
- 10. Components mounting at Panel • Here is the GA drawing of Panel. • Connector is the starting and ending point of all wires. • At the connector we have to inject the current from current injection kit. • O/C R-1 and O/C R-2 indicators are over load or under load indications. • Power On Light is indicating the Power is ON. • A-meter is showing the running actual current. • O/C R-1is Over load current relay, E/F R is Earth fault tripping relay and O/C R-2 is Under load current relay. 04/22/2016 10 A Review of Radial Feeder Protection Concept

- 20. Conclusion From this project, we can protect in distribution system by mostly affecting faults like over current and earth fault with the use of over current and earth fault relay. Use of PSM and TSM, we can trip the relay by different types of timing situation and current. By this set-up, we can study and to understand the basics of terminology. In addition of this project, the electromechanical relay has limited used purpose. We occupied the fault very accurately. 04/22/2016 20 A Review of Radial Feeder Protection Concept
