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.
