How can we calculate cable size in Low voltage & high voltage..

Answer / Sarvesh Singh

Calculating cable sizes for low and high-voltage applications involves considering factors such as current carrying capacity, voltage drop, insulation level, and environmental conditions. For low voltage (LV) applications, the cable size is often determined using tables or charts provided by cable manufacturers based on specific application requirements. High-voltage (HV) cables require more detailed analysis and may involve using formulas such as Ampacity tables, Kelvin law, or Von Damm’s formula.

We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
