Anti-interference Dielectric Loss Tester
Product Brief Introduction:
The anti-interference dielectric loss tester is used for on-site anti-interference dielectric loss measurement, or precision dielectric loss measurement in laboratories. The instrument has an integrated structure, with built-in dielectric loss bridge, variable frequency power supply, test transformer, and standard capacitor, etc. It adopts variable frequency anti-interference and Fourier transform digital filtering technology, fully automatic intelligent measurement, and the measurement data is very stable under strong interference. The measurement results are displayed on a large-screen LCD, and a built-in micro printer can print output.
Product Features:
◆ With positive/reverse wiring, internal/external standard capacitor, internal/external high voltage multiple working modes, integrated structure, can do various conventional dielectric loss tests without any external auxiliary equipment.
◆ LCD display, menu operation, rich test data, automatically distinguish capacitance, inductance, resistance type test objects, built-in micro printer can print output.
◆ With external standard capacitor interface, can connect external oil cup for precision insulating oil dielectric loss test, can connect external solid material measuring electrode for precision insulating material dielectric loss test, and can also connect external high-voltage standard capacitor for high-voltage dielectric loss test.
◆ Automatically recognize 50Hz / 60Hz system power supply, and support generator power supply, even if the frequency fluctuation is large, it can measure normally.
◆ Built-in series and parallel two dielectric loss measurement models, convenient for instrument calibration.
◆ Can store 255 sets of measurement data.
◆ When measuring with CVT self-excitation method, C1/C2 can be measured at one time with one wiring, automatically compensate the influence of busbar grounding and standard capacitor voltage division, no need to change wiring or connect any external accessories.
◆ Chinese graphic menu, large-screen backlit LCD display clearer, real-time monitoring of current and voltage.
◆ Optimized circuit design makes the accuracy and stability of positive/reverse wiring consistent.
◆ Automatically recognize external high-voltage test power supply frequency 40Hz～70Hz, support power frequency power supply, variable frequency power supply and series resonance power supply for large-capacity high-voltage dielectric loss test.
◆ With reverse wiring low-voltage shielding function, under the condition of 220kV CVT busbar grounding, C11 can be measured with 10kV reverse wiring dielectric loss without disassembling the wiring.
◆ With computer interface. Through this interface, measurement, data processing and report output can be realized, and the internal measurement software of the instrument can also be upgraded. It can be integrated into a comprehensive high-voltage test vehicle.
◆ Configured with thermal printer, making printing faster, noiseless and clearer.
◆ Added loop poor contact discharge prompt function to facilitate judging whether the wiring is reliable.
◆ Enhanced reverse wiring low-voltage shielding function, can measure the capacitance and dielectric loss value of two capacitors at one time with one wiring.
◆ Added CVT ratio function, can measure CVT ratio and phase error.
