Feeder Protection

ASHIDA has designed economical & reliable Multifunction Feeder Protection & Control System. The simple and compact construction of ADITYA series ADR245B, ADR241A, ADR241B and ADR241C relays provide integrated Protection, Control and Monitoring functions for Over head Transmission Lines, Underground cables, and Distributed Feeders.

ADR245B, ADR241B & A21F Relays are second generation of Numerical Over current IDMT/DMT Relay. They consist of all the necessary protection and monitoring functions required for Normal feeder. Relay designed with fast and selective tripping ensures the stability and availability of electrical power system. All the latest communication protocols like IEC61850, IEC60870-5-103, MODBUS, DNP3 can be provided in Transformer Protection Relays.

A21F relay provides integrated Protection, Control and Monitoring functions for Over head Transmission Lines, Underground Cables, and Distributed Feeders.The ADR245B relay provides the options for three versions: basic, extended and modular versions. For hardware features of individual models refer the ordering information. The core functionality of all Feeder Protection Relays is equipped with multi-function feeder protection.The High speed Digital Signal Controller, continuously monitors line phase current and E/F current. Along with different status input, through CTs, and optical isolated status connections. The high-speed micro-controller samples these current signals through a A/D converter.

Feeder Protection Relays apply protection, control & monitoring of radial and ring main feeder to achieve sensitivity and selectivity on phase and ground faults. Feeder Protection Relays provide thermal over load protection of transformer against over load conditions. ASHIDA’ Feeder Protection relay offers a perfect solution for integration into your substation automation system or can be used as stand-alone multifunction protection. Further, all of these smart, communicable products have sophisticated functionality for event, alarm and fault analysis.
