Benefits of Partial Discharge Tester
Comprehensive Testing
Combines hipot testing and partial discharge detection in a single test, providing a thorough assessment of insulation integrity.
01
Preventive Maintenance
Early detection of partial discharges allows for proactive maintenance, reducing the risk of catastrophic failures.
02
Improved Reliability
Ensures that electrical equipment can operate reliably under high voltage conditions, preventing unexpected downtimes.
03
Safety Assurance
Helps maintain safety standards by ensuring insulation can withstand operational and overvoltage conditions.
04
Data Analysis
Advanced PD testers often include software for data analysis, trend monitoring, and report generation, aiding in long-term asset management.
05
Application of Partial Discharge Tester
Power Industry
In the power industry, PD tester is mainly used to detect the insulation status of high-voltage switchgear, ring network cabinet, voltage/current transformer, transformer (including dry-type transformer), GIS (gas insulated switchgear), overhead lines and cables.
Railway System
In the railway system, PD tester is used to detect the insulation status of power equipment and signal equipment along the railway, such as traction transformers, signal power transformers, cable lines, etc.
Petrochemical Power Supply System
In the petrochemical power supply system, PD tester is used to detect the insulation status of power equipment such as transformers, cable lines, motors, etc. in petrochemical enterprises.
Aerospace Testing Field
In the aerospace testing field, PD tester is used to detect the insulation status of electrical equipment on aerospace vehicles, including generators, motors, cable lines, etc.
Automotive Industry
In the automotive industry, particularly with electric and hybrid vehicles, PD testers are used to monitor high-voltage batteries and electrical systems, ensuring they are properly insulated.

Please use it indoors, the ambient temperature is -20℃～50℃, and the relative humidity does not exceed 80%.
Please stay away from flammable and explosive dangerous goods.
To prevent interference or leakage accidents, please turn off the power switch when charging.
If liquid or corrosive substances come into contact with the instrument, stop using it immediately and turn it off, and hand it over to professionals for treatment.
The external sensor interface uses an imported connector. Do not rotate the connector to avoid damaging the connector.
When pulling out the sensor connector, just hold the connector of the metal shell and pull it outward. Do not pull the connecting wire.
Before using the external sensor for testing, be sure to connect the sensor to the host before testing. It is strictly forbidden to plug and unplug the test wire during operation!
