This is about the recent problem that we have faced in our project site. We have 6/7.5 MVA. 66/11kV three phase star - star power transformer. The neutral was solidly connected to the earthing mat. But because of high resistance of earthing mat (130 ohm on LV and 180 ohm on HV), one day LV side neutral earthing conductor melted and we had a huge damage. Can any one plz tell me what might happen when we connect power transformer neutral to the earthing mat which has high resistance (>100 ohm ) ?????
