——Strong comprehensive measurement capability. Measurement of various parameters of the on-load tap-changer can be performed in one instrument. Such as the switch selection, switching the whole process of whether there is a break point, transition waveform, transition time, transition resistance, three identical period and so on.
- More comprehensive analysis of measurement results. The user can analyze the resistance value of each point and each segment of the waveform and the time of each segment through the large-screen liquid crystal display, and the time of each segment and the three phases of different phases. Through the screen analysis, the user can understand the switching. During the process, each time the three-phase switch of various parameters changes, but also the waveform printing, storage and access to historical waveform analysis and comparison.
- printout. The instrument is equipped with a panel-type front paper change printer that can be directly archived as a switch test report.
- Menu-driven, flexible operation. All operating functions, hints, and measurement results are displayed on a 240 x 128-dot large-screen LCD. As long as the user presses the function key according to the prompt, the measurement can be performed.
- Has good anti-jamming performance. All-aluminum chassis and instrument are equipped with power noise filter and anti-interference circuit, which can be used for reliable measurement at sites with poor power quality and strong electromagnetic field interference.
- Data retention, data and waveforms measured by the user can be stored in the instrument and the stored contents will not be lost due to power failure.
Transformer on-load switch parameter tester has those advantages?
- Light oscilloscope function. The instrument is divided into three channels, which can simultaneously record all the transitions and transitions in the three-phase transition process of A, B and C, including the time value of the trip point. Not affected by the weather, the function is far superior to a light oscilloscope.
