SCM-PDS1-TEV tev sensor partial discharge

TEV partial discharge sensor’s working principle is based on a direct capacitive coupling with a switchgears earthed metal case. The two ends of TEV sensor can be coupled magnetically to virtually any opening on a metal Surface. It picks up the electric signal given by PD activity onto the two metallic surfaces. Its high sensitivity, easy installation and rigid design make the TEV the best sensor for direct installation on medium and high voltage related equipment.
