  • Circuit breaker / switchgear testing - OMICRON

    The high voltage in switchgear creates stress for the materials being used in the equipment. Therefore, insulation tests are recommended. In principle, GIS systems require exactly the same tests as other systems. However, they are often difficult to access and this is why they require special solutions.

  • Switchgear Monitoring System Market by Switchgear Type

    The high voltage segment held the largest share of the switchgear monitoring system market, by voltage in 2019. The growth of the high voltage segment is driven by the higher demand for monitoring systems on high voltage switchgear. As any fault in switchgear apparatuses is likely to hamper the electricity supply to an entire city or region.
