how to cal calculate capacitance in DC Circuit
Answer / iamdon
Capacitance in DC circuit is calculated as follows.
1)From dimensinal and medium data
C=(A*e)/d
where A=cross sectional area of conductor.
e=permittivity of medium between conductors.
d=physical distance between conductors.
2)From electrical data.
C=Q/V
where Q=charge on conductor
V=potential differece between conductors.

Dear Friends, Need your help for connecting APFC panel, Quotation : I have 2 No’s 1000 KVA Transformers, both transformers are having separate APFC panels, ( Tr-1,400KVAR, TR-2,450 KVAR) Now I want to stop One transformer, present load is 650Amps, Max, So One transformer is enough, I have switched OFF TR-1, but PF is not maintaining properly, its 0.5, So now I want to connect TR-2 APFC also in TR-1 Loads, Can any one answer for my Quotation with drawing, how to connect TR-2 APFC panel in TR-1 Loads,
Pls Breifly explain about UPS (Inverter,Reserve,Rectifier,Float voltage,Boost voltage).
