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?
Why there is no provision of breaker in between primary of UAT and generator
what are the specifications we must look at to select a relay for any capacity motor?
