Hi friends,
few days back i got the below given "Phase sequence detector" from this forum & i tried it. It worked very well. But when i used this circuit in parallel with my 3 phase voltmeter it gave problem. Probelm:- when one of the 3 phases isn't present i.e one phase is open i get voltage in that phase back, rougly around 108 Volts. Ideally it should be 0. I'm unable to find out the reason. I tried inserting some diodes in Phase sequence detector circuit, but no use. Can someone please help me .
Thanks.
