Huazheng Manufacture HZJF91V4 Multifunctional Partial Discharge Tester
The Partial Discharge Tester is a state-of-the-art diagnostic tool that combines advanced technology with user-friendly features. It is engineered to detect, measure, and analyze partial discharges in a wide range of electrical equipment, including transformers, switchgear, cables, and rotating machines. With its high sensitivity and precision, the tester can identify even the smallest discharges, allowing for early intervention and preventive maintenance.
System Introduction
Partial discharge is a symptom and manifestation of insulation degradation in power equipment, and also a cause of further insulation deterioration. Since the consequences of insulation breakdown are often serious, partial discharge detection of power equipment is particularly important. Partial discharge in electrical equipment refers to electrical discharges that do not cause a complete short circuit between electrodes. These discharges typically have small amplitudes, but they can continuously degrade insulation, potentially leading to eventual failure. Live-line partial discharge detection provides a fast and simple method to identify potential insulation faults that could cause power outages or personal injury.
Main Features
1) Allows for quick on-site detection of partial discharge in high-voltage electrical equipment, especially switchgear. It is easy to use, small in size, lightweight, and portable.
2) The partial discharge detection sensor circuit utilizes advanced radio frequency signal processing, high-frequency signal processing, and weak signal processing technologies, and employs high-precision AD conversion and high-speed digital signal processing chips for digital signal processing, resulting in excellent anti-interference performance and measurement accuracy.
3) Integrates multiple detection methods for partial discharge signals, including ultrasonic, transient ground wave, contact ultrasonic, and high-frequency methods.
4) Built-in non-contact airborne acoustic sensor and TEV sensor.
5) Provides multiple display windows for analyzing partial discharge test data, including waveform diagrams, phase diagrams, bar charts, and four-element diagrams.
6) Supports data storage and viewing functions; data can be directly exported via SD card or USB.
7) Supports multi-level threshold settings for warnings and alarms, providing intuitive prompts for problems through different amplitude colors.
8) Powered by a large-capacity lithium battery, allowing for continuous operation for more than 10 hours on a single charge.
