ZXYZ-JZ On Load Tap Changer AC Parameter Tester
Manual
Video1. AC/DC method to test the true transition waveform ( No Filtering processing), suitable for on site test of parameters like transition waveform, transition time, transient resistance and three-phase synchronization.
2. It is easy to judge the on load tap changer when use AC test method. If the total transition waveform is continuous then the working condition is good
3. Can test 10kV~500kV voltage no matter what kind of winding wiring ways.
4. Built in power supply or external connecting power supply. Built in type can output three phase power with simple wire connection, external power supply can make high voltage test, zero sequence test
5. High speed sampling: over 200k/s/channel ( usually DC method speed is 10k/s). Large storage capacity, cache depth up to 8M byte FIFO.
6. With embedded computer and testing software, 10.4” color LCD, touch screen, printer, supporting U disk and USB keyboard and mouse
7. Meet the request of intelligent power grid operation and management system. The on-site operator can connect the sampler with tablet PC and transmit data via internet
8. Can transmit and export the data to office PC for further analysis or editing off line
9. Can work as a digital universal meter
