Capacitance and Dissipation Factor / Tan-Delta Test Set | ATPL TDT M-20 Pro

A Capacitance and Dissipation Factor (Tan-Delta) Test Set is used to evaluate the insulation condition of transformers, cables, and other electrical equipment by measuring capacitance, dissipation factor, and insulation losses, ensuring reliability and early fault detection in power systems.

Designed to measure the dielectric loss of transformers, reactors, capacitors, bushings, and arresters.
It offers robust anti-interference capabilities, swift testing speeds, and high precision.
The equipment automatically presents the phase difference angle and winding polarity.
Featuring a 7" high-resolution color touch screen with a stylus pen.
Users can select from various test modes, including UST, GST, CVT, and GST g.
Equipped with a built-in thermal printer, it can store records of up to 1000 tests.
