JF-2004 Handheld Ultrasonic PD Detector Partial Discharge Tester
Product Description
JF-2004 Handheld Ultrasonic PD Detector Partial Discharge Tester 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 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;
