Scada-Mate^® Switching Systems

Introduction

Scada-Mate Switches are integer style three-pole, group-operated load interrupter switches available in voltage ratings of 14.4 kV through 34.5 kV. They’re factory-assembled on a one-piece base and include an integral stored-energy operating mechanism. Circuit making and breaking are accomplished within sealed interrupters, in a controlled SF6 environment.

A complete S&C Scada-Mate Switching System includes a 5800 Series Automatic Switch Control, which supports the IntelliTEAM II® Automatic Restoration System. IntelliTEAM II is a universal solution for automating new and existing circuits, offering unmatched interoperability. Restoration speed is greatly enhanced when the control is furnished with a SpeedNet™ Radio. It combines extremely secure long-range communication, high-volume data transmission, and flexible mesh networking to provide benchmark performance for unlicensed radio networks.

Alternately, a Communication and Control Unit can be furnished, providing the interface between the switch and the master-station computer for distribution automation and other Smart Grid applications that don’t involve IntelliTEAM II.

High-speed operating linkages are housed within the Scada-Mate Switch base. With no external moving parts, full live-switching performance is assured under any and all ice conditions. Visible air-gap isolation of switched-open circuits — needed only when work on the feeder is required — is provided by an integral, hookstick-operated disconnect.

Two S&C Current Sensors and one S&C Current/Voltage Sensor provide three-phase monitoring of line current and single-phase monitoring of system voltage . . . eliminating the cost, clutter, and complexity associated with separately mounted sensors. Three-phase voltage sensing on one or both sides of the switch is optionally available. The integrated sensors, combined with single-point lifting, make installation quick and easy. The voltage sensors also provide battery-charging power for the automatic switch control or communication and control unit, eliminating the need to install a separate distribution transformer.

All functions — sensing, control, and communication — are thus provided in one economical, completely self-contained, fully tested, integrated package.
