On-Load Tap Changer (OLTC) is indispensable in regulating power transformers used in electrical energy networks and industrial applications. It is a mechanism in transformers which allows for variable turns ratios to be selected in discrete steps. Transformer with this mechanism obtains the variable turn’s ratio by connecting to a number of access points known as taps. These taps are indicated using moving contact potentiometer. This is operated by the rotation mechanism. The proposed work explains technological improvement in indicating the tap position based on different voltage tapping on primary side and to maintain secondary side be consistent voltage using Arduino and required programming.
