Tan Delta measurement is a
proven, simple and reliable test method for evaluating the dielectric
condition of cables and other electrical equipment such as transformers
or rotating machines. "Water-tree" damaged cables can be easily and
clearly identified. The ease of use, low weight and the compact design
is truly impressive. The HVA series HVA90 Insulation Tester and HVA94
Cable Tester (A sinusoidal 0.1 Hz VLF output voltage source test sets)
must be used with the TD90 tan delta testing system, providing a usable
range between 1 to 90 kV peak.
The dissipation factor
measurement is performed with an accuracy of ± 10-4 for loads in the
range of 500 pF to 10 µF. serve as the ideal high voltage source for the
TD90-MC. The TD90-MC provides the testing and commissioning engineer
with versatile high voltage tan delta measurement system suitable for
testing XLPE, PE, EPR and PILC cables or other electrical equipment.
