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, wiring is convenient, and 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 close/open operation based on the reference contact state.
It can detect and prompt the connection status of 6 contacts, making it easy for users to check wiring.
The instrument can store up to 100 sets of test results.
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 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.
