Huazheng Manufacture HZ-9003C Multifunctional Partial Discharge Tester

Introducing the Partial Discharge Tester – the ultimate solution for ensuring the reliability and longevity of your electrical insulation systems. In the world of electrical engineering, the integrity of insulation is paramount. Partial discharges, which are small electrical sparks that occur within insulation, can be early indicators of insulation degradation. Left unchecked, these discharges can lead to catastrophic failures, costly downtime, and extensive repairs. Our Partial Discharge Tester is designed to detect these discharges early, providing you with the critical information needed to maintain the health of your electrical systems.

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.

Operation Notice

1.Read the manual carefully before operating the measuring device.

2.When use different sensors for measurement during the testing, should setup correct parameters at the “ parameter settings” to ensure the measurement accuracy.

3. If needs to replace sensors during the testing, should turn off the “ output voltage”.

4. During the testing, should handle the device with care, to avoid any bumps.

5.After testing, please turn off the power and then charge the device.

Overview

HZ-9003C multifunctional partial discharge tester is used for on-line detection and location of partial discharge of HV equipment, which is designed based on our many years experiences in the partial discharge measuring fields.

The system is equipped with composite TEV sensors, ultrahigh frequency sensors, High-frequency current transformers and high sensitivity ultrasonic sensors to collect partial discharge signals at high voltage equipment. The system adopts multilevel detect frequency reduction techniques to reduce the discharge frequency of the signals, meantime using high-speed AD conversion circuit to complete the signal digitization, also by using digital signal processing, adaptive filtering interference signal processing methods to ensure the reliability of the testing data. By collecting different signals produced from the partial discharge in different high equipment, the equipment operation status can be detected rapidly. The tester can be installed for detection with equipment operation and without any effect to the equipment operation. This will help the workers to make evaluation timely for the switchgear cabinet operation status, and thus greatly improve the equipment operation reliability, safety and effectiveness.

HZ-9003C Multifunctional Partial Discharge Tester include: device host、special partial discharge detection software、TEV sensor (TEV) 、ultrasonic sensor (USS)、ultrasonic concentrator (ELTW) 、high frequency CT (HFCT) 、UHF sensor (UHF) 、earphone and connecting wire.

Investing in the Partial Discharge Tester means investing in the future of your electrical systems. By identifying and addressing partial discharges early, you can prevent costly failures, extend the life of your equipment, and ensure the safety and reliability of your operations. Don’t wait for a problem to arise – take control of your electrical insulation health with the Partial Discharge Tester.
