Dielectric Response Analysis on Power Cables

When the insulation ages, the condition and thereby the dielectric strength of cables also deteriorates. In XLPE cables, electrical trees or water trees, caused by partial discharges or moisture, represent a serious problem.

These changes can be detected by changes in the dielectric response. Therefore, this method is ideally suited for performing cable condition diagnostics. Problems can be detected early and corresponding actions can be performed before any major damage or failures can occur.

Determining the insulation condition

DIRANA is a dielectric test system for insulation assessment that measures dissipation/power factor (tan delta), polarization index (PI) and capacitance.

Wide frequency range

It’s extremely large frequency range, from 10 µHz to 5 kHz, makes DIRANA the perfect tool for the condition assessment of all types of high- and medium-voltage cables.

Software support with PTM

The easy to use Primary Test Manager ™ (PTM) software determines all relevant parameters, offers multiple ways for insulation analysis and requires no expert knowledge.

Easy and comfortable testing

All required components come in one box, making it easy to transport (19 kg/ 42 lbs). It’s simple wiring concept and clamps with integrated guard connections make setting up tests easy and fast for all type of assets.
