EMA Electromechanics, Inc.

EMA Electromechanics is the designer and manufacturer of the VDH/GSMI combined 34.5 kV outdoor vacuum circuit breaker and high-speed, mechanically interlocked grounding switch, a unique and patented system specifically designed for application with wind power substations. This design totally replaces traditional use of the conventional outdoor substation circuit breaker and its associated oil insulated grounding transformer in every feeder of a wind power substation, with very noticeable technical and economic advantages. VDH/GSMI also provides better safety and reliability for wind power plants and their personnel than remote transfer trip schemes.
