JF-2004 Easy Use Portable Transformer Partial Discharge Detector

Introduction:

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.

It is widely used in the following fields:

• Development and distribution enterprises
• Railway system
• Petrochemical power supply system
• Aerospace testing field
• Automatic testing field

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.

Main Features:

1. Configure different sensors to realize partial discharge detection of almost all electrical equipment;
2. The humanized man-machine interface facilitates data management of different devices, including traceback of historical data change trends, and horizontal and vertical data analysis, and realizes 360 ° comprehensive diagnosis of the device under test;
3. 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;
4. Adopt a non-intrusive detection method, no power failure during the test, and maybe no high voltage source is applied, which is more convenient to use than a traditional pulsed partial discharge detector;
5. The test bandwidth range is 30kHz ~ 2.0GHz, suitable for the detection principle of various frequency bands;
