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

APPLICATION OF CURRENT DIFFERENTIAL PROTECTION TO TAPPED TRANSMISSION LINES
1. Introduction
Microprocessor-based current differential relays offer superior protection for power transmission lines. The key advantages over distance relays include better sensitivity for high resistance faults, 100% line protection, and better performance in the single-pole-tripping mode, particularly during evolving and cross-country faults. Besides the well-known requirements of high-speed communication and sampling synchronization, a microp ....etc

System for power transformer differential protection
In this invention, Current transformer (CT) secondary currents for the windings of a power transformer are used to produce a differential current and An operating current value is obtained from the differential current value. A restraining current value is obtained from processed winding current values.

TECHNICAL FIELD:
It pertains to the transformer internal fault protection for electric power transformers

BACKGROUND
In the occurrence of internal faults in a ....etc
