TEV - Transient Earth Voltage

TEV sensor is a partial discharge sensor whose working principle is based on a direct Capacitive coupling with a Switchgears earthed metal case.


  • High sensitivity, Thanks to its special design has high sensitivity, larger than other single ended TEV sensors
  • Cheap, compact and robust, his compact and robust design(passive sensor) makes the TEV the optimal sensor for direct installation on medium voltage Switchgears
