Abstract

Electrical machine rating is dependent on temperature. The rate at which heat generated in an electrical machine is transferred usually determine the life span of the machine. In this work a monitoring system has been presented. It consist of a power supply unit, the Real time clock unit based on DS3231 Integrated circuit, a 3V Cmos battery and 32 kHz Crystal Oscillator, a temperature sensing unit built around DS18B20 sensor, an analogue to digital converter integrated circuit (ADC0804) and a programmable control unit based on ATMEGA328P microcontroller. On test with an electric motor, a range of temperature measured over 30minutes at an interval of 1 minute were displayed.
