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:

Lets,


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
