The TD30 tan delta test system is a portable cable diagnostics system for confirming the dielectric condition of medium voltage cables. The battery powered, weight optimized device - only 3 kg - is perfectly suitable for mobile use.

The HVA34 must be used with TD30 tan delta test system, usable over a range between 1 to 34 kV peak. The dissipation factor measurement is performed with an accuracy of ± 10exp-4 for loads in the range of 500 pF to 10 μF.
