  • 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.

  • TECHNICAL INFORMATION UltraTEV Monitor

    2020-7-17When partial discharge activity occurs within high voltage switchgear it generates Transient Earth Voltages (TEV) and electromagnetic waves in the radio frequency range. The TEV signals are high frequency and therefore travel in the skin of the switchgear and can only escape from the inside of the switchgear through openings in the metal casing.
