If the angle between current phasor and voltage phasor becomes equal to zero then such circuits are called pure resistive and if that angle becomes equal to 90 , it is pure inductive and if the angle becomes -90 , it is pure capacitive. Here current phasor is taken as reference..

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.
