RELAY CO-ORDINATION
Done at FACT, COCHIN DIVISION
Submitted by,
SREERAJ V SUBEESHKS SHY AMKUMAR RB TED XA VIER ANTONY
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- ....etc

abstract

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 appli ....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
