Answer / lalit

if we talk about the generator then we have to classify the
active power as well as reactive power i.e. V*I because the
reactive power is also used in generator for the excitation
purpose( for flux production). hence its rated as MVA in
other hand, for power transmission only active power is used
i.e. VICos theeta. hence its rated as Mw.

Answer / k.prakashchandra

The capacity is decided by prime mover

Answer / koteswararao

In generator to generate the reactive power in combination of voltage and current base so it ishaving both specification in MVA in plant capacity is combination of reactive power and power factor. how much load taken byplant.

I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
