Switch characteristic tester is a special instrument developed by the company to meet the needs of various high-voltage switch action characteristics tests, and can accurately measure various oil grades such as less oil, more oil, vacuum, sulfur hexafluoride, etc. Mechanical dynamic characteristics of high voltage circuit breakers.
For circuit breakers (like this) with closing resistors, the closing resistor and switching waveform can be accurately measured. The instrument adopts large-screen display, Chinese characters prompt man-machine dialogue operation, Chinese characters display results and printout, with intelligent, multi-function, accurate data, strong anti-interference, simple operation, small size, light weight, beautiful appearance, etc.
The AC Voltage Test Set T 22/1 is a portable test set consisting of two separate units: the control unit and the medium-voltage equipment unit. This division enables the operator to use the test set on site without transport aids.
The test set can be equipped with a rectifier attachment for DC voltage testing up to 80 kV.
Action voltage dc30-250v / 20A digital adjustable circuit breaker action power supply is provided in the unit, which automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker.
