Wiring Method of High Voltage Switch Characteristic Tester
High Voltage Switch Characteristic Tester can be used for testing and measuring the mechanical characteristic parameters of high voltage switches in power systems of various voltage levels, including vacuum, SF6, low oil, and multi-oil types. The measurement data is stable, the wiring is convenient, and the operation is simple, making it the most convenient tool for high voltage switch maintenance and testing.
The instrument can automatically identify the open/close state of the contacts and prompt the corresponding closing or opening operation based on the reference contact state.
It can detect and prompt the connection status of 6 contacts, making it convenient for users to check the wiring.
The instrument can store 100 sets of test results internally.
Large screen LCD (320×240) display, advanced gray screen, no reflection or black screen under sunlight, with graphic and Chinese menu operation prompts, user-friendly menu interface, and simple operation.
The instrument has powerful graphic analysis functions, enabling simultaneous display of waveforms and processed measurement data on the same screen, making the testing process more intuitive.
The instrument is equipped with a delay protection function, which automatically cuts off the coil voltage after the circuit breaker operates, effectively protecting the circuit breaker equipment and the high voltage switch tester.
This instrument can perform electric open/close tests and manual open/close tests.
It can perform high and low voltage tests.
