"As the market for XLPE insulated power cable grows and matures, the emphasis is moving towards quality of production. This change has been brought about by a few failures on major new power transmission projects and also because of the increase in diversity of supply. The quality of electrical power cable is assured by post production partial discharge testing. This delivers the result to the factory or process manager days or even weeks after the cable has been produced. By necessity the plant managers and process owners tend to be very cautious in their approach to manufacture in order to minimize the risk of failure in final test. The UltraSense monitor from IPEC is located immediately after the end of the CV tube and it yields detailed information on the quality of the cable insulation at that point. This early information helps the Process owner or manager to make informed decisions that can reduce scrap and increase yields."

UltraSense system provides immediate visual information and alarms for the operator on dimensions, centering and material quality. The information is logged and transmitted over the factory network for analysis by the process manager.
UltraSense technology is being extended to provide 100% coverage of the outer as well as inner semiconductor interface and to apply the measurement to processes with complex temperature gradients.
The UltraSense monitor has been commissioned with minimal intervention from IPEC. This is achieved with on-line support using a VPN link. This has facilitated training of operators and the supervision of the calibration of UltraSense.
The benefit UltraSense provides is in the early presentation of explicit information on different types of flaw. These examples show how the information on flaws is presented to the operator and to the process manager.
