Gdgs Automatic Transformer Power Factor Tester

GDGS Automatic Dielectric Loss Tangent Delta Tester for Transformer

1. Features
* GDGS Transformer Tan Delta Tester is used to measure dissipation factor (PF) in heavy interference site such as power plants or power substations. It can also be used in laboratory for high accurate test.
* GDGS Transformer Tan Delta Tester is whole in one designed: Including precision digital bridge, power unit, reference capacitor (CN), step-up transformer and other electronic circuits. It's also using frequency shift technology, FFT (Fast Fourier Transform algorithm) and digital filtering. When started, it's running automatically and then outputs the results on LCD display and prints the results automatically.
