T-206 Transformer dielectric loss tan delta tester can effectively find damp, deterioration and defects of electrical equipment insulation widely used in electrical manufacturing quality control.

The anti-interference precision dielectric loss tan delta tester is used for on-site or laboratory dielectric loss measurement. The Transformer tan delta tester is an integrated with built-in dielectric loss bridge, variable variable frequency power supply, test transformer and standard capacitor test.

The instrument has frequency conversion, anti-interference and Fourier transform digital filtering technology.  It is able to work in a high interference environment for ease of mind. The unit includes a large screen display, and micro printer to print test results.

  • With positive / reverse wiring, internal / external standard capacitor, internal / external high voltage, reverse connection, low voltage shielding, CVT and variable ratio, and other modes of operation. Automatically distinguish capacitance, inductance, resistance type test sample. Integrated structure, fully automatic, intelligent measurement, easy to use and carry.
  • With ordinary measurement and accurate measurement mode.Testing speed under accurate measurement mode is slower than the ordinary measurement mode, and is suitable for big interference in scene occasions. For common scene occasions, ordinary measurement mode can be used..
  • The frequency conversion anti-interference can be measured accurately under 200% interference, and the test data is stable. It is suitable to do the anti-interference dielectric loss test on the spot.
  • By using digital waveform analysis and Bridge self calibration technology, the accuracy and stability of the positive / reverse connection are consistent. With high-precision three terminal standard capacitor, high precision dielectric loss measurement is realized.
  • Built in series and parallel dielectric loss measurement model, and can simulate voltage capacitor bridge and current comparator for convenient instrument verification.
  • During CVT self excitation magnetic measurement, the measuring line can be connected with the floor, C1/C2 can be measured at the same time to automatically compensate the voltage sharing effect of ground busbarbar and standard capacitor, without changing line and external parts.
  • The utility model has the function of reverse connection and low voltage shielding. Under the condition of 220kV CVT ground busbarbar, the C11 can be carried out the measuring of the dielectric loss of the lower shield without disconnecting the 10kV , and simultaneously measuring the capacitance and the dielectric loss of the lower shielding part.
  • With CVT ratio measurement function, it can measure the CVT ratio, polarity and phase error.
  • Safety measures High voltage protection: Under condition of short circuit, breakdown or high voltage current fluctuation, it can cut off output at a high speed by short circuit mode. Power supply protection: incorrect connection of 380V, power supply fluctuation or sudden power failure, it will start protection and avoid to cause over-voltage. Ground protection: it has the function of ground wiring detection and can not step up when it is not grounded. If the instrument is not grounded properly, the ground protection is started. CVT protection: four protection limits of voltage and current in high voltage, voltage and voltage and current in low voltage side to protect the equipment; the wrong menu will not output the exciting voltage. In CVT measurement without 10kV high voltage output. Anti misoperation: two level power switch; real-time monitoring of voltage and current; repeated key confirmation; distinctive terminal of high / low voltage; slow step-up; quick decompression; sound and light alarm. Anti – “Capacitance rise”: when measuring large capacitance sample, the “rise” effect of voltage can occur. The instrument can automatically track the output voltage and keep the test voltage constant. High voltage cable: high voltage insulated wire can be used even connecting the floor. Anti-seismic performance: the instrument adopts unique anti-seismic design, and can withstand strong long-distance transportation, vibration and jolt without damage.
  • Print storage: instrument with a micro printer, and you can print and output the measurement results. The measurement results will be stored into the device (which can store 100 sets of measurements) or U disk for checking in the future..
