Answer / shyam

dear
sir; send all electrical ans so idont no DG KVA
Rating.....

Answer / ankit goel

dg rating is in kva b'cuz the current from a generator has 2 components resistive and reactive. we utilize resistive power but reactive power also flows so to decide the size of conductor both needs to be considered and kva being the resultant of both we give kva rating.

Answer / any

we know that P= vi*p.f now at the time of manufacturing
manufacture don't know what is the power factor of load so i
think its rated in VI=VA

an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly
