Abstract


The main criteria required for all the electrical and electronic device is the voltage. It plays vital role in a power quality. It is planned to provide a transformer with multiple taps and selecting the taps required for the moment will be automatically selected by the on-load changeover system which is operated by the controller. Computer acts as a controller with the aid of the C software. Voltage transducers are used to sense the voltage and ADC to convert into digital signals. These digital signals arte interfaced with computer which in turns operates the On Load Tap Changers (OLTC). Suitable taps are selected and its drive relays are operated by the computer through opto-coupler and switching transistors.
