Aerial bundled cables/conductors are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor.
This contrasts with the traditional practice of using uninsulated conductors separated by air gaps.
This variation of bundled conductors utilizes the same principles as overhead power lines, except that they are closer together to the point of touching but each conductor is surrounded by an insulating layer
Permissible overload = Full load kVA*factor for permissible load
= 1240 kVA
The reactive VAR required = kW*(tanφ1 -tanφ2)
Cosφ1 = 0.8
φ1 = 36.87 deg.
Cosφ2 = 0
φ2 = 0 deg.
kVAR required = kW*(tan(36.87) - tan(0))
= 225.00 kVAR
Per phase value = 225.00/3
= 75 kVAR
