Product Description

XHJF Series partial discharge tester

 

This instrument is designed for collecting and detecting partial discharge signals emitted from insulation defects in electric equipment. The absence of discharge signals does not necessarily indicate the absence of discharge activity in the equipment, as discharge sources often have a latent period and insulation performance may also fail due to other reasons beyond partial discharge. If significant discharge is detected in equipment connected to medium and high voltage power systems, the relevant responsible units should be notified immediately.


Xhjf Series New Arrival Partial Discharge Measuring Instrument Pd Inspector for High Voltage Electrical Equipment
Partial discharge is a sign and manifestation of insulation deterioration in power equipment, and it is also the cause of further insulation deterioration.  Since the consequences of insulation breakdown are often serious, it is particularly important to conduct partial discharge detection on power equipment.  The local discharge of electrical equipment belongs to electrical discharge that will not completely short-circuit the electrodes.

Although the amplitude of this discharge is usually small, it can continuously degrade the insulation performance and may eventually lead to failure.  Live partial discharge detection provides a fast and simple method to identify potential insulation faults that may cause power outages or personnel injuries.

This instrument uses high-frequency detection technology to measure partial discharge and comprehensively applies computer technology, ultrasonic, radio frequency, transient waveform sampling technology, analog electronic technology, high-speed signal acquisition technology, and advanced digital signal processing technology.

It is developed based on the Linux operating system platform, providing 2D and 3D maps of partial discharge, amplitude phase spectrum waveform, and discharge signal quantification value.  By statically or dynamically observing and analyzing the partial discharge pulse waveform of a single or multiple cycles in detail, the partial discharge condition of electrical equipment can be evaluated well.  It is suitable for daily inspection of the insulation performance of high-voltage cables, power transformers, and other electrical equipment.  It has the characteristics of high sensitivity and strong adaptability and can effectively detect related insulation defects.  It is an ideal tool for state detection of power equipment during live operation.

cables. It is convenient to use, small in size, lightweight, and easy to carry.
2. The partial discharge detection sensor circuit design utilizes advanced RF signal processing, high-frequency signal processing, and
weak signal processing technology. It uses high-precision AD conversion and high-speed digital signal processing chips for digital signal
processing, with good anti-interference performance and measurement accuracy.
3. Multiple methods are used to detect partial discharge signals, including ultrasonic, transient earth wave, high frequency, and very high-frequency detection.
4. It has a built-in non-contact air-coupled sensor, and can be configured with an external surface-coupled ultrasonic sensor.
5. It provides various analysis window options, including phase-linear, PRPD, and PRPS to analyze partial discharge test data.
6. It supports data storage, viewing, and deletion functions.
7. It supports waveform data recording function.
8. It supports multiple levels of attention and alarm threshold settings. Different amplitude colors provide intuitive prompts to indicate potential
issues.
9. It is powered by a large-capacity lithium battery, providing 6 to 8 hours of continuous operation on a single charge.
10. It uses Linux as the embedded operating system, making it convenient for future function expansion and integration with IoT technology.
