“REMOTELY MONITORING OF TRANSFORMERS PARAMETERS AND PROTECTION AGAINST OVERLOAD”
Under Guidance of Prof. Yashit D. Tita BE Electrical Department, Dr. Subhash Technical Campus Junagadh, Gujarat, India., India
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.
