Answer Posted / inderpreet singh
There are many Advantages/reasons that the tap changer is connected to High voltage, some are described below:
1.HV winding is easy to Tap because HV winding is always placed on LV winding and LV winding is placed near to core due to insulation and cost constraints.
2. For keeping voltage at consumer end constant, Tap changer is provided on HV side.
3 In Electromagnetic field theory, Voltage & Current are inversely proportional to each other. where voltages are high currents will be low, when tap changer is connected to HV it will lead to avoid heavy inrush of current while tap changed.
