General Information:
UNGK-H Circuit Breaker Tester is designed to test the mechanical dynamic characteristics various voltage degree vacuum, SF6, with oil and etc. high voltage and low voltage circuit breakers.
Features:
1. 7 inch large color LCD, can read clearly even in direct sunlight.
2. Friendly English interface, touching key, easy to operate.
3. Build-in printer.
4. Integrated power supply, suitable for on-site test. DC20-265V adjustable power source, current 15A. The active voltage value of open/close coil can be set arbitrarily, the low voltage action of circuit breaker is also can be tested.
5. Universal type velocity sensor, easy to install.
6. All the data and graph can be available only by one time switching.
7. To be suitable for all kinds of GIS, SF6/vacuum/oil switchgears.
8. 6000 groups data storage (memory card is extendable). Built-in clock to save the test date and time.
9. USB port, to save the data to the U disk.
10. 12 channels metal contactors, three channels closing resistance measurement.
11. Built-in anti interference circuit, suitable for 500kV substation reliable testing.
