Suppose we have a load capacity of the P
load power factor of Cos is φ1 → tg φ1 (before compensation)
power factor after compensation is φ2 → tg φ2 Cos.
Reactive power compensation is necessary Qb = P (tgφ1 - tgφ2).
From the capacity to compensate us accordingly selected capacitor in the supplier's catalog tables capacitor
compensation.
