UHF-OTS SENSOR

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

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.

具有全向性、高增益 (2.8 dBi及高頻寬響應特性。
工作頻率範圍在 300MHz~3000MHz ，符合局部放電所產生的電磁波頻率範圍。
全向性與高增益的特性，不易受現場環境雜訊干擾，提高檢測部分放電的靈敏度。
基座法蘭與變壓器絕緣油接觸之介質檢測視窗，採用鐵氟龍 (Polytetrafluoroethene,PTFE) 製作成圓筒形，具耐高壓拉力、耐高溫及抗油性等特性，並以雙重油封環密封，具雙向逆止防滲漏能力，可承受10 bar以上壓力。
天線設計為可拆卸結構，如需維護感測器時，變壓器不需停電、洩油，只需將感測器的固定螺絲拆卸即可維護或更換，使用安全無虞。
防護等級 IP67。
