We have three 33kv substations. All of them energised by
same source.When i am checking the phase sequence between
one substation to other substation
(like R Phase to R Phase) by multimeter i am getting
some voltage.Near to LT panels UPS panels are there. Can u
explain whether any possible to happen
like that. In Phase SEquencemeter is showing correctly
in both substations. How is it happen. Explain me.Explain
me communication signal will produce
Phase difference on this case.
