Major insulation in a transformer is the insulation between the LV Winding and Core and also in between LV winding and HV winding.
If a sinusoidal voltage source is connected to a power transformer, it's no load current would be
On no load phasor diagram of transformer, the core loss component of the current remains in phase with
