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.
How to calculate the Harmonics losses in terms of
How 48-relay (incomplete sequence) functions?
why constant voltage transformer should be start without
load? and if started then what will happen?
can we conduct the swineburne's test on a dc series motor?
what shoud be strength and weakness to impress
what is impedence of transformer?
I have 2500KVA transformer delta/star,13.8KV/380V provided
with LV 4000A breaker. Already I have 2300KW motor feeder
with a full load 90%. Is it possible to connect another
1600A from that breaker? If so how the calculation is done?
