Product introduction:
Guanfeng brand-automatic anti-interference dielectric loss tester is used for on-site anti-interference dielectric loss measurement, or precision dielectric loss measurement in the laboratory. The instrument is an integrated structure, built-in dielectric loss bridge, variable frequency power supply, test transformer and standard capacitors. Guanfeng brand-automatic anti-jamming dielectric loss tester adopts frequency conversion anti-interference and Fourier transform digital filter technology, automatic intelligent measurement, and the measurement data under strong interference is very stable. The measurement results are displayed on a large-screen liquid crystal display with a printable output from a mini-printer.
Product Features:
â—† It has positive/negative wiring, internal/external standard capacitance, multiple working modes of internal/external high voltage, integrated structure, and can be used for various conventional dielectric loss tests without external auxiliary equipment.
â—†Liquid crystal display, menu operation, rich test data, auto-resolve capacitance, inductance, resistance type test products, comes with a micro-printer can print out.
â—† With an external standard capacitor interface, external oil cup can be used for precision dielectric dielectric loss test, external solid material measuring electrode can be used for precise dielectric material dielectric loss test, and high voltage standard capacitor can also be used for high voltage dielectric loss test.
â—† Automatically identify 50Hz/60Hz system power supply, and support generator power supply, even if the frequency fluctuation is large, it can also measure normally.
â—† Built-in series and parallel dielectric loss measurement models to facilitate instrument verification.
â—† can store 255 sets of measurement data.
â—† CVT self-excitation measurement, C1/C2 can be measured at the same time a single wiring, automatic compensation busbar grounding and standard capacitor partial pressure effects, without changing lines and any external accessories.
