JF-2004 China Made Ultrasonic Method Handheld Partial Discharge Detector
Product Description
The detector is used for the detection and evaluation of the insulation status of high-voltage switchgear, ring network cabinets, transformers, GIS, overhead lines, cable terminals, cable branch boxes and other equipment.
Partial discharge intensity detection: By measuring the discharge signal within a power frequency period, the intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.
Partial discharge frequency detection: The device measures the discharge signal within a power frequency period, extracts discharge pulses, and characterizes the frequency of partial discharges according to the number of discharge pulses

Features
- Configure different sensors to realize partial discharge detection of almost all electrical equipment;
- Humanized man-machine interface facilitates data management of different devices, including traceback of historical data change trends, horizontal and vertical data analysis, and realizes 360 ° comprehensive diagnosis of the device under test;
- Built-in ultrasonic sensors and transient ground voltage (hereinafter referred to as TEV) sensors, which can be connected with special sensors such as transformers, GIS, overhead lines, and cables;
- Adopt a non-intrusive detection method, no power failure during the test, maybe no high voltage source is applied, which is more convenient to use than traditional pulsed partial discharge detector;
- The test bandwidth range is 30kHz ~ 2.0GHz, suitable for the detection principle of various frequency bands.
