Description

The TDB-60 is used for measuring the loss angle, or dissipation factor, of shielded power cable. These measurements are used to track the deterioration of cable insulation. Increasing Tan Delta numbers indicate increasing cable insulation degradation. TD measurements are used to establish baseline readings on new installations, for trending cable condition over time, and to help prioritize cable replacement and/ or cable injection programs.

Tan Delta testing is performed with the cable off-line. A VLF AC test instrument is used to provide the test voltage to the cable while the TD device records the results. It is an easy test to perform and provides valuable information about cable insulation integrity.
