Scada-Mate SD Switching Systems

Scada-Mate® SD Switching Systems

For outdoor distribution, 14.4 kV and 25 kV

Three-pole operated switching systems for overhead distributed automation uses a vacuum interrupting medium, has no greenhouse gas and is environmentally friendly

As energy demand and generation capacity continue to grow, utilities are looking for distribution switching systems that are reliable, resilient, and efficient.  When used with smart and flexible controls they can minimize the load under outage conditions and maximize their system uptime.The Scada-Mate SD Switching System with an S&C 6801 Automatic Switch Control can meet these technical, operational, and economic challenges. The switching system includes vacuum interrupting technology, has no greenhouse gas and is totally environmentally friendly.The three-pole operated Scada-Mate SD Switching System is designed for overhead distributed automation and to operate in 14.4-kV and 25-kV power distribution systems. It is rated 900 amperes continuous and interrupting and features peak withstand of 41,600 amperes. It has a five-time duty-cycle fault-closing rating of 12,500 amperes RMS symmetrical.

Features

• An integral stored-energy operating mechanism. Circuit-making and circuit-breaking are accomplished within sealed vacuum interrupter bottles. In addition to electrically operating the interrupters, the operating mechanism provides non-electrical mechanical opening and closing of the interrupters by means of a manual-operation pull-ring.
• An OPEN/CLOSED indicator. Located on the side of the base, the indicator shows the interrupter position.
• A Lockout/Tagout feature. The switch can be locked open to prevent electrical or manual closing.
• An optional hookstick-operated disconnect. Visible air-gap isolation of switched-open circuits—needed only when work on the feeder is required—can be provided by an optional integral, hookstick-operated disconnect.
• A permanent lifting bracket. The bracket is provided for convenient rigging and hoisting, thus making Scada-Mate SD switches easy to install.
• Voltage and current sensing. Scada-Mate SD Switching Systems can be furnished with factory-installed three-phase S&C Current Sensors or three-phase S&C Current/Voltage Sensors on one or both sides of the switch. Alternately, S&C sensors or sensors of other manufacturer can be added later. With their integral sensors and disconnect—and no vertical operating pipe—Scada-Mate SD switches present a clean, uncluttered look.
