WebSep 17, 2016 · Tap changing causes change in leakage reactance, core loss, copper loss and perhaps some problems in the parallel operation of dissimilar transformer. There are two methods of tap changing. 1. Off load tap changing 2. On load tap changing 1. Off load (No load or off circuit) tap changing WebSep 3, 2015 · The tap changer is located in HV winding in Resiglas dry type transformers. Setting the tap involves simply changing the order of connections between particular taps, identically on all HV windings. Lower values on LV terminals means that lower values on HV terminals as well, thus the tap changer must be set for lowering the HV, for instance ...
