rmsvoltage/averagevoltage=form factor,in
transmisson,distibution systems voltages are rms only,the
form factir of sinesoidal wave is 1.11

As per standard, transformer body earthing and other Equipment earthing (Equipment earthing) did not connect. but in LT side termination we are doing metal glanding in both side Transformer to PCC Panel through armoured cable, now X'mer body earthing and PCC Pane earthing (Equipment earthing) both are connect.is this safe for X'mer or other equipment?
