Partial discharge diagnosis

HV DAC Series

Test- and diagnostic system for High-Voltage cables

The HV DAC series are designed for after laying tests on newly installed HV-cables as part of quality control, and for condition assessment on repaired or service-aged HV-cables. The key benefit of this test set is the compactness versus testable capacity. With this transportable unit cables with a length up to 32km can be tested. In addition set-up within a substation is also no problem; no more roadblocks needed compared to using resonance test sets on large trucks.

As of its portability and short set-up time it is possible to quickly respond on changing weather conditions. As of its low weight there are no special requirements needed for road conditions. Air transport is also no problem, keeping transportation times to a minimum and maximizing the efficiency in use of the system.

The test set incorporates a partial discharge (PD) detector, allowing monitoring the quality of workmanship and the condition of the cable. The PD measurement system is state of the art with live evaluation, localization and display of results. Maintenance activities can be directly planned during the actual measurement. All data is stored in a powerful cable data base, where data can be easily accessed again, and reports printed.
