Active Ultra High Frequency Sensor (UHF–GIS)
​主動式超高頻感測器

  • With characteristics of omnidirectional, high gain (2.8 dBi) and high bandwidth response.
  • Bandwidth ranges from 300MHz to 3000MHz, corresponding to electromagnetic wave frequency.
  • ​Reduce jamming from surroundings and thus raises sensitivity for PD detection with its high omnidirectional and high gain features.
  • The material of inspect window with cylinder shape between flange and insulation oil is enhanced polytetrafluoroethene (PTFE), enduring high pressure and temperature. Sealed with double oil rings which has bidirectional backstop ability to prevent leaking, bearing pressure of 10 bars or above.
  • The removable structure design makes it easy to do maintenance for sensor without turning off power or leaking oil of transformer, which is safe to use.
  • Protection level IP67.
  • 具有響應頻寬高、重量輕、體積小之局部放電感測器。
  • 工作頻率範圍在300MHz-3GHz，符合局部放電所產生的電磁波頻率範圍。
  • 堅固的外型與便於安裝於GIS定點監測。
  • 本身設計有效排除不必要的雜訊與干擾。
  • 適用於GIS及EBG量測。
