Dx8000 full-automatic dielectric loss tester with different frequency is a high-precision instrument for testing dielectric loss tangent and capacitance of various high-voltage power equipment in power plants, substations and other fields or laboratories. The instrument is an integrated structure with built-in dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The test high-voltage source is generated by the inverter inside the instrument and is used for the test object after boosting the voltage of the transformer. The frequency can be changed into 50Hz, 47.5hz 52.5hz, 45Hz 55Hz, 60Hz, 57.5hz 62.5hz, 55Hz 65Hz. The digital notch technology is adopted to avoid the interference of power frequency electric field to the test, which fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, it is suitable for the situation that the generator is used for power supply detection after power failure. The instrument is equipped with insulating oil cup and temperature control device to test the dielectric loss of insulating oil.

clear, the operator can use without additional professional training. At present, it is a very ideal intelligent dielectric loss measuring equipment.

Mass storage data

The instrument is equipped with a calendar chip and a large capacity memory, which can save 200 groups of data, save the test results in chronological order, view the history at any time, and print out.

Scientific and advanced data management

The instrument data can be exported through U disk, and can be viewed and managed on any PC through our company's special software.

Various test modes

The instrument can be tested by internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self excitation method, etc. under external standard external high voltage, it can be used for high voltage (more than 10kV) dielectric loss.

One step CVT test in place

The instrument can also test the dielectric loss and capacitance of the fully sealed CVT (capacitive voltage transformer) C1 and C2, and realize the simultaneous test of C1 and C2. The instrument can also test CVT ratio and voltage angle difference.

CVT measurement without removing the high voltage lead

The instrument can correctly measure the dielectric loss and capacitance of CVT without removing the high voltage lead of CVT.

CVT reverse shielding method for C0 measurement

The instrument can measure the dielectric loss value and capacitance value of C0 at the upper end of CVT by reverse shielding method.

High speed sampling signal

The inverter and sampling circuit inside the instrument are all controlled by digitization, and the output voltage is continuously adjustable.

Multiple protection is safe and reliable

The instrument has multiple protection measures such as input voltage fluctuation, high-voltage current, output short circuit, power failure, over-voltage, over-current, temperature, etc., which ensures the safety and reliability of the instrument. The instrument also has the function of setting grounding detection to ensure that the equipment without grounding is not allowed to boost voltage.
