Tan Delta (TD) - also referred to as Dissipation Factor or sometime even Power Factor - is an excellent diagnostic test that provides an indication as to the quality of the dielectric insulation used in electrical apparatus. By analyzing the dielectric losses in theinsulation, the GDGS Series of Tan Delta test instruments provide the testing engineer with a versatile high voltage diagnostic system that is suitable for testing MV cable such as XLPE, EPR, PE and PILC. In addition, other electrical apparatus such as capacitors, transformers and large rotating machines can also be diagnosed.
GDGS Automatic 10KV Tan Delta & Dissipation Factor 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.
The 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.
