Static Var Generator (SVG)

Intelligent Power Factor Correction — Real-Time, Accurate, Maintenance-Free

What is an SVG?

A Static Var Generator is a fully electronic reactive power compensation system. Unlike APFC capacitor banks, SVG delivers smooth and continuous PF correction — without switching surges, capacitor failures or delays.

Ideal for

Elevators, HVAC & cranes
Injection moulding machines
Pharma packaging lines
Hospitals & labs
Commercial complexes
Any facility with fluctuating loads
