Answer / guest

kvar denotes the units of reactive power and it is given by


Q=V*V/X


where v denotes voltage and x denotes capacitive reactance


and capacitive reactance is given by



x=1/(2*pi*f*c)
f=frequency and pi=22/7 and c= capacitance for which unit
is farad

Answer / venkat

calculate the Capacitve reactance (Xc) = V/I
Then apply the formula C ( in Farads) = 1/2*3.414*F*Xc

I want to ask a question which i faced during testing of Capacitive Voltage Transformer in AIS. We have measured the C1 , C2 individually , but when we start to measure the total C1+C2 , the testing equipment shuts down and says low loading. Kindly is it possible to find the total capacitance by using measuring device. kindly briefly explain the procedure.
