and is use there load is used in
variable form.and we have different
ways of power sourses and for
synchronization voltage , freq,and
phase sequence should be remain same.

last week we did the REF relay test by closing single pole (R phase) of CB and apply 380V at the primary of delta transformer. we get 33A at the primary of the R phase star end. but we get 380A at both R an B in delta side. how and why?
