JKZ- ⅰ on-load tap switch tester

The JKZ-I on load tap changer tester is used to test the switching status of on load switches. On site personnel can test the performance of on load switches of various power transformers without dismantling transformers or lifting switches, and display and print waveforms and parameters of the transition process.
Main functions and features:
1. Powerful function, capable of measuring parameters such as transition waveform and transition time, transition resistance, three-phase synchronicity, etc.
2. Large screen dot matrix LCD display, hierarchical Chinese menu, easy and fast operation.
3. Intelligent testing and result analysis, with the ability to amplify or reduce waveform test results.
4. Independent voltage regulators are suitable for measurement without windings, while independent constant current sources are suitable for measurement with and without windings.
5. Six independent signal processing, high-speed A/D conversion, 10KHz high-speed sampling, truly reflecting parameter changes.
6. The instrument is equipped with an uninterruptible memory that can store three sets of waveforms and data, which can be archived, accessed, and analyzed at any time.
7. The instrument comes with a perpetual calendar that displays the date and time, and can automatically print.
8. There is a high-speed printer that can print test results.
