Calculation of Sag
Calculation of Sag:
The sag & tension of conductor may be calculated in the following condition:
a) When the supports are at equal levels.
b) When the supports are at unequal levels.
i) Sag calculation when supports are at equal levels:
A conductor is in the two equal level supports A...

Power Factor correction using static capacitor
Calculation formulas as follows:
Q1 = I losses + Cu losses
Q2 = PkW · (Tanφ1 – Tanφ2)
I losses = 2% · Str
Cu losses = USC% · Str
Q = Q1 + Q2
