RELAY INTERFACE

The circuit diagram shows the connection of Relay Driver Circuit. When the logic signal from the Buffer O/P is applied to base of the transistor through resistor 1KOhm the starts conducting, it energizes the relay. The transistor act as a small signal amplifier resistor of 1KOhm is used to provide proper emitter base voltage to turn the transistor to ON state from OFF state.

Relay is an electromechanical switch & it works on the principled energizing an electromagnet. It consists of primary coil, 2 contacts one ....etc

Frame Relay is a high-performance WAN protocol that operates at the physical and data page link layers of the OSI reference model. Frame Relay originally was designed for use across Integrated Services Digital Network (ISDN) interfaces. Today, it is used over a variety of other network interfaces as well. This chapter focuses on Frame Relay s specifications and applicat ....etc

Abstract
This paper describes modelling and testing of a
digital distance relay for transmission line protection using
MATLAB/SIMULINK. SIMULINK s Power System Blockset
(PSB) is used for detailed modelling of a power system
network and fault simulation. MATLAB is used to implement
programs of digital distance relaying algorithms and to serve
as main software environment. The technique is an
interactive simulation environment for relaying algorithm
design and evaluatio ....etc

PROJECT REPORT ON
RELAY CO-ORDINATION
Done at FACT, COCHIN DIVISION

ABSTRACT
The purpose of the protective relays and protective relaying systems is to operate the correct circuit breakers so as to disconnect only the faulty equipment from the system as quickly as possible thus minimizing the trouble and damage caused by faults when they do occur. Relays have revolutionized protection control metering and communication in power systems. Relay co-ordination will help to isolate the faulty region in the power system s ....etc

A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. Relays allow one circuit to switch a second circuit which can be completely separate from the first. For example a low voltage battery circuit can use a relay to switch a 230V AC mains circuit. There is no electrical connection inside the relay between the two circuits, the page link is magnetic and mechanical
