“REMOTELY MONITORING OF TRANSFORMERS PARAMETERS AND PROTECTION AGAINST OVERLOAD”

Abstract

In power system a distribution transformer is a very important device. Transformer is a
electrical equipment so there are some faults occur like overloading, over-current, over-voltage, overtemperature etc. So prevent these faults we can Monitoring this parameter and give protection of
transformer. The transformer parameters are monitoring by remotely through GSM modem. This system
consists microcontroller of 8051 family and a rectified power supply. Microcontroller and sensors are
interface through the Analog to Digital Converter (ADC). Sometimes in distribution transformer on the
secondary side load is increase due to increase power consumption. When the transformer get overloading
after some limit trip the transformer and give alert to the operator through GSM. Due to this over-current
may be occurring and it causes the failure of transformer. Voltage, Temperature, Current of transformer can
be monitored. Proteus Simulation is carried out for the parameter monitoring.
