what happen when power factor of 2 parallely operated transformer become equle?
In Fluorescent tube there is a writing like 6500k . what this 6500k represents?
Dear all, how we select the cable size according to current with or without including different correction factor , is there any direct method for sizing of cable...
v=I*R, i.e V is directly proportional to I. now P=V*I. so V=P/I. thus v is inversely proportional to I. so what is the correct one? If both are correct than for which kind of condition this 2 differ
what must be the mf for a meter with the following conditions. line ct ratio-100/1 line pt ratio- 220kv/110v meter pt ratio- 3X63.5V meter CT ratio- -/1 A
is there any lightning by passer is arranged in ship like buildings?
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.
What is Phase to Phase clearance for 800V System Operating Voltage as per IEC61439
When we change the tap position of 10MVA transformer it suddenly tripped with Out of step indication and also with Static differential relay indication, Transformer Bucholz relay indn and Low oil level indication. Before 1 week the same problem occured by changing the tap position. but at that time only oltc bucholz relay activated. After testing the TxR Relay team & PET team cant find any solid reason. The values are ok also. So plz answer wat's the reason for this incident? anybody plz help.
why cant we use earth as neutral at home whereas neutral is actually grounded at transformer end?
