12KV Transformer Capacitance & Tan Delta Test Set Automatic 0-12KV HV Output

12KV Transformer Capacitance & Tan Delta Tester , Automatic Tan Delta Tester , Generator Tan Delta Tester

I. Products Description

FKGST 12KV Tan Delta (dissipation factor) Tester consists of variable frequency power, tan delta bridge, testing transformer and standard capacitor inside the tester. Variable frequency power can produce five kinds of frequency: 45Hz, 50Hz, 55Hz, 60Hz and 65Hz under which test can be done. Variable frequency technique adopted in this tester can ensure high accuracy in high interference environment.

Model FKGST Automatic 12KV Capacitance ＆Dissipation Factor Test Set 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 meter 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.
