What are Relays?
 Relays are electrical switches that open or close another circuit under certain conditions.
 Relay Purpose
 Relay Types
Electromagnetic Relays (EMRs)
 EMRs consist of an input coil that's wound to accept a particular voltage signal, plus a set of one or more contacts that rely on an armature (or lever) activated by the energized coil to open or close an electrical circuit.
 Solid-state Relays (SSRs)
 SSRs use semiconductor output ....etc

TRANSFORMER PRO TECTION USING NUMERICAL RELAY
PROJECT REPORT
Submitted by
AMBILY G ASHA V N SHYAMA K
INTRODUCTION
The aim of this project is to analyze and upgrade existing transformer protection system in BPCL Kochi Refinery. Transformers are static devices totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However the consequences of even a rare fault may be very serious unless the transformer is quickly disconnected from the system. This necessitates providing ....etc

Impact of Distributed Resources on Distribution Relay Protection


Introduction
The use of distributed resources has increased substantially since 1998 because of the potential to provide increased reliability and lower cost of power delivery to customers. The addition of a distributed resource (DR) to a power system, particularly to the distribution system, introduces system conditions not otherwise encountered. These conditions can have a serious impact on th ....etc

PROJECT REPORT
Submitted by
AJU.M.PAULOSE BUOY THOMAS HAPPY VARGHESE RONY ITTAN SUJITH.S
INTRODUCTION
The aim of this project was to analyze and upgrade the existing generator protection system in BPCL-Kochi Refinery, Kochi. Power generation occupies the prime place in power system. Industrial and commercial power system may include generator as a local source of energy. These generators supply all or part of the total energy required or they ....etc
