Transformer 10KV Tan Delta Tester (CDEF)
1.1 Introduction Automatic 10KV 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 set 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.
