With the inductive load drivers they control, Sigma’s SVC-supported reactive power control relays rapidly commission single-phase shunt reactors by triggering them at specific firing angles via thyristors as required.

Designed to drive three single-phase shunt reactors, Sigma Inductive Load Drivers monitor the reactor power in each phase independently. Consequently, the reactive power required for each phase can be controlled precisely and independently.

With their specially designed cooling systems, Sigma Inductive Load Drivers operate at full performance without being affected by temperature variations within compensation panels.
