What's Your Power Quality Problem?


With the ever increasing use of sophisticated controls and equipment in industrial, commercial, institutional and government facilities, the continuity, reliability and quality of electrical service has become extremely crucial to many power users.  Even momentary voltage fluctuations can disastrously impact production and extended outages are much worse.

Introducing the Most Complete Family of Power Quality Solutions in the Industry.

S&C's PureWave™ family can solve virtually any power quality problem.  All medium voltage systems feature S&C's PureWave Power Electronic Switches that provide sub-cycle switching, in combination with time proven S&C Metal-Enclosed Switchgear.

S&C PureWave Source-Transfer System is ideal for facilities served by two independent power sources.  In the event of a voltage fluctuation or an outage on one source, the system seamless transfers to the other source before critical loads are affected, typically within two to four milliseconds.

S&C PureWave UPS System provides enhanced service continuity to facilities served by a single power source, where momentary disruptions are of concern.  It's ideal for loads up to 15 MVA and supports the load through momentary voltage fluctuations and interruptions lasting up to 30 seconds.  The PureWave UPS System can be applied in conjunction with a backup generator, set to start up while the system is serving the load.  This arrangement assures seamless service through extended outages.

S&C PureWave Voltage Support System is perfect for installations where the power source is subject only to short-term voltage sags, typically emanating from the transmission system and other feeders.  It corrects for momentary sags of 10% to 50% nominal voltage.
