局部放電是評估中高壓設備絕緣狀態的重要指標之一。YTC9100手持式地電波局部放電檢測儀/云定位儀用于中低壓開關柜( 3 ~ 66kV )的局部放電的測量和定位。儀器采用暫態地電壓傳感器檢測和定位開關柜的絕緣內部放電，結合先進的云計算和智能建模技術，實現局部放電信號的測量、記錄、傳輸、存儲、分析和交換，為局部放電的現場測量提供了強大的技術支撐。測量人員利用YTC9100采集局部放電信息，通過云計算可實時對檢測設備絕緣狀態進行智能診斷。

Partial discharge is one of the important indexes to evaluate the insulation state of medium and high voltage equipment. Ytc9100 handheld ground wave partial discharge detector / cloud locator is used for partial discharge measurement and positioning of medium and low voltage switchgear (3 ~ 66kV). The instrument adopts transient ground voltage sensor to detect and locate the insulation internal discharge of the switchgear. Combined with advanced cloud computing and intelligent modeling technology, it realizes the measurement, recording, transmission, storage, analysis and exchange of partial discharge signals, which provides strong technical support for the on-site measurement of partial discharge. The surveyors use ytc9100 to collect partial discharge information, and can intelligently diagnose the insulation state of the detection equipment in real time through cloud computing.
