CT6000 PRECISION DIELECTRIC LOSS MEASURING INSTRUMENT

1. It has multiple working modes such as positive/reverse wiring, internal/external standard capacitance, internal/external high voltage, reverse wiring low-voltage shielding, CVT and transformation ratio. Can automatically distinguish capacitance, inductance, and resistance type samples. Integrated structure, automatic and intelligent measurement, easy to use and carry.

2. Frequency conversion anti-interference, accurate measurement under 200% interference, stable test data, suitable for on-site anti-interference dielectric loss test.

3. Using digital waveform analysis and bridge self-calibration technology, the accuracy and stability of the positive and negative wiring are consistent, and the high-precision three-terminal standard capacitor is used to achieve high-precision dielectric loss measurement.

4. Built-in series and parallel dielectric loss measurement models, and can simulate the work of Xilin bridge and current comparator, which is convenient for instrument verification.

5. During CVT self-excitation measurement, the measuring line can be grounded, and C1/C2 can be measured at the same time during one connection. It automatically compensates for the effect of busbar grounding and the partial voltage of standard capacitors, without changing wires and connecting any external accessories.

6. With reverse wiring low-voltage shielding function, when the 220kVCVT bus is grounded, 10kV reverse wiring dielectric loss measurement can be performed on C11 without disconnecting the wiring, and the capacitance and dielectric loss value of the lower shielding part can be measured at the same time.

7. With CVT ratio measurement function, it can measure CVT ratio, polarity and phase error.

8. Safety measures

High-voltage protection: short-circuit, breakdown or high-voltage current fluctuations of the test product can cut off the output at a high speed in a short-circuit mode.

Power supply protection: wrong connection of 380V, power supply fluctuation or sudden power failure, start protection, will not cause overvoltage.

Grounding protection: It has a grounding detection function, and the voltage cannot be boosted when it is not grounded. If the grounding of the instrument is poor during the measurement process, the grounding protection will be activated.

CVT protection: Four protection limits for high-voltage side voltage and current, low-voltage side voltage and current, will not damage the equipment; wrong menu selection will not output excitation voltage. There is no 10kV high voltage output during CVT measurement.

Misoperation prevention: two-level power switch; real-time monitoring of voltage and current; multiple keystrokes to confirm; terminal high/low voltage is distinct; slow boosting, rapid decompression, sound and light alarm.

Anti- "capacity rise": When measuring large-capacity samples, there will be a "capacity rise" effect of increased voltage. The instrument can automatically track the output voltage and keep the test voltage constant.

High-voltage cable: It is a high-voltage resistant insulated wire that can be used for mopping the ground.

Anti-seismic performance: The instrument adopts a unique anti-seismic design, which can withstand strong long-distance transportation vibration and bumps without being damaged.

9. Print and storage: The instrument comes with a micro-printer, which can print out the measurement results and store the measurement results in the instrument (100 sets of measurement data can be stored) or U disk for future reference.

10. Real-time clock: the instrument has a real-time clock, real-time display, and can record the date and time of the measurement.
