With hopes to enhance its power quality offering, S&C Electric, Chicago, recently purchased the Adaptive VAR compensator product line from Trench Limited of Canada, Scarborough, Ontario. The product line will now be marketed as PureWave AVC.

Pioneered by Trench in 1990 in cooperation with the University of Washington, the AVC technology included in the VAR compensator uses power-electronic switching to provide variable amounts of reactive compensation on a cycle-by-cycle basis.

The new product line will be the newest member of S&C’s family of power-electronic switching systems.
