HZ-9003C Handheld Multifunctional Partial Discharge Tester

Overview

The HZ-9003C multifunctional partial discharge tester is designed for on-line detection and location of partial discharge in high-voltage equipment. It is developed based on our extensive experience in the field of partial discharge measurement.

System Overview

The system is equipped with composite TEV sensors, ultra-high frequency (UHF) sensors, high-frequency current transformers (HFCT), and high-sensitivity ultrasonic sensors to collect partial discharge signals from high-voltage equipment. It employs multilevel detection frequency reduction techniques to lower the discharge frequency of signals, while utilizing high-speed AD conversion circuits for signal digitization. Digital signal processing and adaptive filtering interference suppression methods ensure the reliability of test data.

By collecting various signals generated by partial discharge in different high-voltage equipment, the system enables rapid assessment of equipment operating status. The tester can be installed for online detection without affecting equipment operation, allowing workers to promptly evaluate switchgear cabinet conditions. This significantly improves equipment operational reliability, safety, and effectiveness.

System Components

The HZ-9003C includes:

• Device host

• Specialized partial discharge detection software

• TEV sensor

• Ultrasonic sensor (USS)

• Ultrasonic concentrator (ELTW)

• High-frequency current transformer (HFCT)

• UHF sensor

• Earphone and connecting cables
