Product Features
1, Strong comprehensive measurement capability. Within one instrument, it can measure various parameters of the on-load tap changer, such as whether there are breakpoints during the selector and diverter switch entire process, transition waveform, transition time, transition resistance, three-phase synchronization, etc.
2,Comprehensive analysis of measurement results. Users can analyze the resistance value at each point and segment, the time of each segment, and the three-phase asynchronism through the large LCD screen and function keys. By analyzing on the screen, they can understand the changes of various parameters of the three-phase switch at each instant during the switching process. They can also print, store, and review historical waveforms for analysis and comparison.
3,Print output. The instrument is equipped with a panel-mounted front paper-loading printer, which can directly serve as a test report for the switch for archiving.
4,Menu-driven, flexible operation. All operation functions, prompts, and measurement results are displayed on a large LCD screen with 240×128 dots. Users can perform measurements by pressing function keys according to the prompts.
5,The instrument is equipped with anti-surge and overvoltage protection circuits. All external leads are sent to the measurement circuit through the protection system, preventing damage to the instrument due to instantaneous discharge of large inductors or wiring errors.
6, Good anti-interference performance. The all-aluminum alloy chassis and the instrument are equipped with a power supply noise filter and anti-interference circuits, allowing reliable measurement in environments with poor power quality and strong electromagnetic field interference.
7, Power-off data retention. The data and waveforms measured by the user can be stored separately in the instrument, and the stored content will not be lost due to power failure. It is especially suitable for returning to the laboratory after on-site tests for further analysis and archiving.
