1 2812As 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?
1179Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
