Re: q : phase failure
your idea is a good idea but i have a question to make it more clear
this relay monitor the change in the phase and detect it but with refrence to what ??
i mean
if the phases is a,b,c and while the operation it become b,a,c it is easy to detect it ............... "while "
but if it come a,b,c and i switch off the electricity and when i switch it on again it come b,a,c ........... so there was no energy in the relay when the phase reversed so how it will detect this .
i don't know much about relayes so forgive me for this question if it is stuiped
