Capacitance And Dissipation Factor Tester

  • Different Frequency Automatic Dielectric is a high-precision instrument, that can be applied to automatically measure electrical loss tangent and capacitance of all kinds of high voltage electrical equipment on the spot of power plants, substations, laboratories, etc. The instrument is an integrated structure with a dielectric loss test bridge, a variable frequency power supply, a step-up transformer, and an SF6 high stability standard capacitor. High voltage source inverter test generated inside the instrument, the transformer voltage for sample test.If the frequency is 50Hz,47.5Hz \52.5Hz,45Hz\55Hz,60Hz,57.5Hz\62.5Hz,55Hz\65Hz, the digital notch filter is used to avoid the interference of the power frequency electric field to the test, which solves the problem of accurate measurement under the strong electric field interference. At the same time, the utility model is suitable for the occasions that the generator is used for power supply after the power cut. The instrument with an insulation cup can test the dielectric loss of insulating oil.

Product Feature And Application

1.Large LCD display

Simple operation, the instrument is equipped with a high-end full touch LCD screen, and super touch interface, each process is very clear, and the operator does not need additional professional training can be used.  Click on it to complete the whole process of measurement, is a very ideal intelligent dielectric loss measurement equipment.

2.Mass storage data

The instrument is equipped with a calendar chip and large capacity memory, the test results can be stored in chronological order, at any time to view the history, and can print output.

3.Multiple test modes

The instrument can use high pressure, high voltage, standard, standard, positive connection method and reverse connection method, self- excitation method and other methods can do testing;  high voltage in standard high voltage conditions (greater than 10kV) dielectric loss.

4.CVT test step in place

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

5.Do not dismantle the high-voltage lead measurement CVT

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