If you multiply R (resistance in ohms) by C (capacitance in
microF) you'll get a value equal to the time constant of
the circuit in seconds. Remember that Xc = 1/(2*PI*F*C) and
that F = 1/T, then substituting and leaving out all
constants and applying a dimensional analysis you'll get
R*C = Time in sec. for that particular cct. (theoretical
value).

We have two APFC panels in same station. I need how to connect CT in two APFC panels.can we take one CT in series connection or two separate CTs.
we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
