Transient Earth Voltage Sensor (TEV Sensor)
暫態地電壓感測器​
High sensitivity | Wide Bandwidth | PD Sensor
  • Detect voltage spike generated from the metal casing of HV equipment.
  • Locate PD source in HV equipment by the amplitude of transient earth voltage.
  • Magnetically attached to the outer surface of metal clad of HV equipment.
  • Suitable for oil-immersed transformers, HV switchgears, and GIS PD detection.
  • The response rising time of pulse for PD detection can reach the nanosecond level.
高靈敏度 | 高頻寬 | 局放檢測用 
迅速檢測電力設備發生局部放電時，鐵磁外殼感應之瞬態地電壓。可利用瞬態地電壓信號大小，定位局放發生位置。具有強磁性吸盤，可靈活吸附在高壓設備鐵磁外殼表面。 適用於具有鐵磁外殼的油浸式變壓器及高壓配電盤、氣體絕緣開關(GIS)等局放監測使用。 探測局放脈衝響應速度可達ns等級。
