Detuned Power Factor Compensator

In Powernac Series P.F. Compensation System the power range goes from 50 kvar to 1000 kvar. Designed for medium to large load networks. They are highly reliable, cost-effective solution for maintaining high network power factor.


Ultimate solution for power factor compensation of unbalanced loads. The compensation is released by measuring the reactive power of the system, through 3 CTs from all 3 phases. This makes it best suited even for most unbalanced loads apart from balanced loads.
