Design and Implementation of a GSM-based Monitoring System for a Distribution Transformer

Maintaining the distribution power substation's health and reliability has been an issue for many years. A typical transformer measurement device detects only one characteristic, such as power, current, voltage, or phase. While some methods can detect several factors, acquisition time operation parameters are too long, testing speed is insufficient. However, a monitoring system that check temperature level of continuously predict faults overheating, overcurrent, after which fault diagnosis relayed to base station through GSM modem developed in this paper. After receiving message any abnormality remedial action be taken immediately prevent catastrophic failures transformers. Key components used development ATmega328 microcontroller, modem, LM35 sensor, ACS712 current so on. The GSM-based preferable manual since it not always possible monitor ambient rise, load manually.
