1933i want to measure voltage difference between neutral and earth so i just simply use voltmeter. my question is that may i use this measure continuosly.or there are some electricity board restrication on that? or it creat some problem on my measuring device..?

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
