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?

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
