Data record gloss.tan-delta.usage

Verified 2026-10-27 Confidence: High

In cable diagnostics a tan delta measurement is made at the test voltage with the measuring head at high voltage potential close to the cable under test, and the voltage, the current and the loss factor are displayed graphically while the test runs. The display lets a deteriorating cable be recognized early and the voltage load on it kept to a minimum, and the loss factor is used to recognize and quantify aging effects such as moisture and water treeing.
