Answer Posted / jamil akhtar
three phase wiring may in star or delta. In case of star
red, yellow and blue wires will be phases and the fourth
wire will be called neutral, In delta no neutral wire is
present.
Megger is a measurement of insulation of winding/windings
with respect to ground or earth.
