Parameters of dielectric loss tester

Product nickname:

Dielectric loss tester, anti-interference dielectric loss tester, fully automatic dielectric loss tester, inter frequency dielectric loss tester, inter frequency dielectric loss tester, anti-interference dielectric loss tester, fully automatic dielectric loss tester

Product Features:

◆ It has positive/reverse wiring, internal/external standard capacitors, multiple working modes of internal/external high voltage, integrated structure, and can perform various conventional dielectric loss tests without the need for any external auxiliary equipment.
LCD display, menu operation, rich test data, automatic discrimination of capacitive, inductive, and resistive samples, with a built-in micro printer for printing output.
◆ It has an external standard capacitor interface, which can be connected to an oil cup for precision insulation oil dielectric loss testing, an external solid material measuring electrode for precision insulation material dielectric loss testing, and an external high-voltage standard capacitor for high-voltage dielectric loss testing.
◆ Automatically identify 50Hz/60Hz system power supply and support generator power supply, even if the frequency fluctuates greatly, it can still be measured normally.
Built in series and parallel dielectric loss measurement models for easy instrument calibration.
Can store 255 sets of measurement data.
When using the CVT self-excited method for measurement, C1/C2 can be measured simultaneously with one wiring, automatically compensating for the effects of bus grounding and standard capacitor voltage division, without the need for wire replacement or external accessories.
Chinese graphic menu, large backlit LCD display for clearer clarity, real-time monitoring of current and voltage.
Optimized circuit design ensures the accuracy and stability of forward/reverse wiring.
◆ Automatically identify the frequency of the external high-voltage test power supply between 40Hz and 70Hz, supporting high-capacity and high-voltage dielectric loss tests for power frequency power supplies, variable frequency power supplies, and series resonant power supplies.
◆ It has the function of reverse wiring low voltage shielding, and can measure the dielectric loss of C11 without disconnecting the 10kV reverse wiring when the 220kV CVT bus is grounded.
◆ Equipped with computer interface. Through this interface, measurement, data processing, and report output can be achieved, as well as upgrading the internal measurement software of the instrument. Can be integrated into a comprehensive high-voltage test vehicle.
