Cable Tester

In the power system, the existing preventive withstand tests for cables are unable to detect minor insulation defects that may lead to insulation hazards. Long-term practice has proven that partial discharge is the main cause of insulation breakdown in power cables after operation. Therefore, conducting partial discharge tests on cables is an excellent method for detecting the insulation condition of cables. Currently, oscillating wave cable detection and localization technology are widely used internationally. Based on this theory, our company has innovatively utilized AC variable frequency high-voltage sources to develop a new type of The cable testing system boasts independent intellectual property rights.

Technical Features:

Compared to existing preventive withstand tests, this technology can non-destructively detect minor quality defects in cables, particularly insulation defects caused by inadequate on-site joint manufacturing processes. It can also pinpoint the location of the defects, eliminating the risk of operating with safety hazards and preventing operational safety accidents. On-site cable condition assessments can be conducted to scientifically determine whether the cable requires supervised operation, defect repair, or replacement.

◆ Adopting alternating current chargingAC-OWTSThe system installation principle is superior to the existing DC systems domestically and internationally.DC-OWTSTechnology to avoid the "false breakdown" effect in cables caused by DC charging, more in line withXLPEThe insulating material characteristics of cables, enabling better testing of partial discharge in old operating cables.

◆ Based on partial discharge information data, the inception voltage of partial discharge for each phase cable can be determined.PDIVNo content provided for translation.PDMax), and documented in the report for future reference to quickly and accurately understand the cable's operational status.

Proven through practice, the oscillating wave method for cable partial discharge locationOWTSThe testing equipment demonstrates excellent detection effects on the quality of the cable's body, accessories, and jointing techniques.

The system is fully compatible with existing national and industry standards, and the test will not damage the cables.
