Product Description
Transformer capacitance & dissipation factor measuring bridge
Description
This different-frequency capacitance & dissipation factor tester is an up-to-date test instrument for measuring capacitance and dissipation factor (dielectric loss and impedance) of various kind of high voltage apparatus full automatically, such as transformers, cables, capacitors, insulators, HV switches, arresters, etc.
This is a high precision instrument; main power is generated by inverter inside and boosted by transformer. Frequency of main power is 45Hz and 55Hz, different to power frequency and so avoid interference by power frequency! It is also suitable for the case that power supply is by generator.
Main features
- Portable type, very light weight, not more than 30kg
- Equipped with big screen (240x128mm), menu displaying with relative prompts in the right side, very simple operation, no need special training.
- Test result can be saved or printed out; One time operation, automatic finish all the test.
- Equipped with big capacity memory and calendar CMOS chip. Test results can be saved in time/date sequence; History records can be reviewed and printed out at any time.
- Equipped with wiring diagram menu inside helping operator to wire correctly.
- Equipped with earth detecting to ensure reliable earthed before being stepped up.
- By equipped with insulation oil cup, this instrument can also test dielectric loss of insulation oil.
- Can be suitable for testing full-sealed capacitor type voltage transformer.
- Inside inverter and sample circuit are all digital control, output voltage is continuous adjustable
- Equipped with multi-safety protection measures for voltage fluctuation, output short-circuit, over-voltage, over-current, over-temperature, etc.
