Why Transformer Neutral having one earth pit ( more earth electrode resistance) whereas body have many earth pit ( less earth electrode resistance)?
which are the criterias needed to select the kind of neutral earthing(solid earthing,resistance earthing,etc.) at various voltage levels in electrical distribution?
exactly how does an RTD 3 wire or 4 wire device cancel out the resistance of the wires , opposed to a 2 wire RTD? Is it because you have resistors in parallel , or because something to do with the electronic circuit the RTD is connected to ?
