  • High Voltage Switchgear SF6 Maintenance

    100 Mass Flow Controller Just like the main circuit breaker in your home, city grids have main on/off switches called switchgears. When these high voltage switchgears open or close, huge lightning-like arcs of electricity are created. If not maintained correctly, these sparks can cause widespread power outages and pose a safety risk.
