Answer / srij21

Ask the questions clearly .i think u want to know the
rating of the UPS to be used.For this u should know the
load that is to be connected with the UPS.Based upon the
load ,u convert the load to KVA ( if the calculated load is
KW) and ask for the UPS supplier to give the ratings list.
Or else u call the UPS supplier and give him the list.he
will guide you.

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.
