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

Output relay Back-EMF Protection



Description

When an electric lock is de-energised, the collapsing magnetic field produces energy to be
generated within the windings of the coil. This energy produces a voltage (or EMF) within the
coil, of the opposite polarity to the normally applied voltage used to energise the magnet.
This back-EMF can result in hundreds of volts and can cause damage to the switching relay,
as it sparks across the contacts.
It is normal practice to install a diode, or bridge rect ....etc

The system includes facilities for discrimination between the internal fault current and the magnetizing input current, differential protection, over current protection, over voltage protection and low voltage protection. This article has explained and designed the software and hardware system based on microcontrollers.


The protection of power transformers is a very difficult problem in the retransmission of the power system. Since it is very important to minimize the frequency and duration o ....etc
