I.Overview Of Instrument

Interelectric damage measurement is a very basic method in the insulation test, which can effectively find the overall damp deterioration of the electrical equipment insulation, and the local defects. It is widely used in electrical manufacturing, electrical equipment installation, handover and preventive test. The dielectric damage measurement of transformer, transformer, reactor, capacitor and casing and lightning arrester is the most basic method to measure its insulation performance. breaks through the traditional bridge measurement method, using frequency conversion power supply technology, using single chip computer, and modern electronic technology for automatic frequency conversion, analog / digital conversion and data operation, fast test speed, high accuracy, automatic digital, easy operation; power using high power switch, output 45Hz and 55Hz pure sine wave, automatic pressure, can provide up to 500 V voltage; automatic filter 50Hz interference, suitable for substation electromagnetic interference field test. Widely used in the transformer, transformer, casing, capacitor, lightning arrester and other equipment in the power industry.

II. Technical Indicators

Introduction Of Instrument Function

1.CN socket- -is the measurement input of the external standard capacitance signal, which is empty when the internal standard is used.

2.CX socket- -is the measurement input end of test product signal, which is connected by a special low-voltage cable, a single-layer shield with a special crocodile clip, 8m long and low end of test product. This end is empty during the reverse wiring.

3.RS232 interface- -It is used to connect the computer, control the instrument, and upload the data.

4.U disk socket- -used to export the data stored by the instrument.

5. Printer- -Print the measurement data.

6. Color touch screen display- -640 * 480 resolution, control and display the menu and various prompts and measurement results.

7. Ground terminal- -is the grounding wire terminal.

8. High voltage switch- -Responsible for starting and closing the high voltage power supply inside the instrument. Close only with external high pressure, and remain open for the rest of the time.

9. Power outlet- -AC 220V ± 10%, 50 ± 1Hz power input with 5A pipe.10.Power switch- -Turn on and off of the whole machine power supply.
