    Medium Voltage Distribution

    GMA "efficient", a product of experienceSchneider Electric has developed gas-insulated switchgear specially dedicated to Medium-Voltage networks for more than 30 years now.The GMA efficient range has been specially designed on the basis of this extensive experience. The first GMA cubicles have been on the market since 1995.The challenge with this new GMA stage has been to merge the experience learned from more than 50,000 first-generation GMA cubicles installed worldwide with the ever-increasing needs of MV switchboard users.

    A wide choice of configurationsThe GMA "efficient" range covers all the usual functions required in Medium-Voltage switchboards such as outgoing and incoming feeder panels which are supplemented by couplings, busbar risers and fuse-switch disconnector combinations.

  • Efficiency - Less space & more powerful Less spaceA GMA switchboard requires 25% less space (footprint) and minimum 30% less volume than other GIS solution.

    More powerful- Maximum technical data at 24 kV: 2500 A nominal current; short-circuit current up to 31.5 kA-3 s.- 450 mm outgoing feeders up to 630 A (i.e. around 80% of customers needs).Additionally the 450mm wide feeder can be executed as 800A outgoing feeder! - 2500 A incoming feeder only 800 mm width, without any fan cooling.- 2500 A coupler-riser only 1000 mm width, without any fan cooling.

    Medium Voltage Distribution GMA "key benefits"

    Gas Insulated SwitchgearVacuum circuit-breaker Technology up to 24 kV - 2500 A - 31.5 kA

    Safety above all Safe by design - Due to their design, GMA "efficient" cubicles cannot be affected by moisture, dirt or polluted operating environments, since all high-voltage parts are contained in a tightly sealed stainless steel tank. - An easy-to-understand system, including mechanical and electrical interlocks to prevent operating errors.- Prevention of possibly dangerous design (for example, no Voltage Transformer positioned above the fully insulated busbar).

    Internal arc withstand, tested and certified according to IEC 62271-200.All compartments are internal arc tested.- Cable compartment.- Circuit breaker compartment.- Busbar compartment.Thus, GMA "efficient" switchgears assemblies are fully tested for resistor earthed grids and isolated grids.

  • Simplicity - "Intuitive operation" as a trademark Intuitive operationThe mechanical operation panel is a trademark for Schneider Electric Gas-Insulated Switchgear- Intuitive design.- Clear positioning of operating and indicating elements in a mimic diagram.- Position indication and operating elements are mechanically independent of the auxiliary voltage.- Integrated mechanical interlocks can be included on option for fully remote control.

    Operation heights ergonomically designed The cubicle architecture and component location are designed to ensure easy, safe operations during the installation, operating and maintenance phases. Four examples regarding Voltage Transformers (VT):- No VT mounting on site. - VTs on cable side or busbar are fixed to the cubicle and mounted and tested in the factory.- Both VTs, cable side or busbar, can be executed with a disconnecting switch.- The operating handle for the VT disconnecting switch is positioned at the front of the switchgear, behind the cable compartment cover (see picture).

    Environment-minded Environmentally friendly construction- Gas weight 50% lower than in customary GIS devices in this market segment.- Volume and weight reduced by 20% meaning less transport resources, less materials needed etc.- 15% less power consumption in primary part.

    Closed gas handling circuit during manufacturing and at site- No gas work on site for any assembly or dismantling work.- At end of life, the gas will be fed into a recycling process (recovery valve).- No factory-special tool required for gas removal; all gas tanks are equipped with a valve in standard use.

    GMA even more efficient with GemControl

    Smart Grids, a true new way of thinkingFaced with demand for an increasing number of energy production sources and the increasingly significant obligations of network adaptability, operators are looking for more flexible, responsive, scalable and simply reconfigurable solutions ("Smart Grids"). It is fundamental for operators to know, understand and act correctly. To know the switchboard status at all times. To act with full knowledge of the facts.

    The choice of a system totally dedicated to the the installations control & monitoring functionsTrue dedication, without reliance upon other low-voltage functions such as protection, provides new benefits: Incomparable flexibility in all phases of design, parameter setting, operation and upgrading of installations control & monitoring; Improved reliability; Flexible and expandable for future needs and growth; Unequalled performance; Real optimization of costs.

    Open SCADA-communication, able to handle all standard IEC and industry protocolsGemControl Base Unit is ready for communication with all standard IEC protocol and industry process control communication systems. Serial links or Ethernet. Protocols: IEC 60870-5-101, Modbus-RTU, Profibus-DP, IEC 60870-5-103, IEC 60870-5-104, IEC 61850, Modbus TCP.

    Intuitive operation as a trademarkLike the cubicles, the Human Machine Interface (HMI) has been specially developed to meet the most demanding operator ease and safety requirements.A true Schneider Electric trademark.GemControl: Just obvious!
