GE's Medium Voltage LIS Retrofit solution reduces arc flash incident energy levels

GE’s Medium Voltage LIS Retrofit solution is designed to provide reduced arc flash incident energy levels for customers on their existing MV equipment. This new solution retrofits a fixed mounted IEC SecoVac VB2 Plus vacuum circuit breaker (VCB) into the fused compartment of LIS.

The Medium Voltage LIS Retrofit solution offers:

  • Reduced arc flash levels from the transformer down to the LV system
  • Transformer protection via the latest relay technology (bus and transformer differential protection)
  • Added transformer protection via an optional snubber application
  • Relay options that provide upstream and/or downstream communications
  • Retrofitting into your existing LIS enclosure
  • Minimal downtime for installation and commissioning (approx. 8-12 hours)
  • The added reliability and quality of an IEC-rated, fast-acting, 3-cycle Vacuum Circuit Breaker with embedded pole technology
  • A separate low voltage door to permit access during maintenance, without the need to open the high voltage compartment
