Descriptions

1. Easy setting, the device boost voltage and automatically plot the volt-ampere characteristic test curve, eliminating the tedious work of manual voltage regulation, manual recording and curve tracing automatically.
2. It tests volt-ampere characteristics, variable ratio and polarity of CT or PT, error curve of 10%, angle error and ratio error.
3.External booster expands the output voltage range.
4. Volt-ampere characteristic test: single machine output voltage 0-2500V, current 0-20A; using the external booster output voltage 0-4000V, current 0-1.5A, 500KV grade 1A CTs' volt-ampere characteristic test can be done.
5.220V single power input ,avoids the danger of using 380V.
6. Large screen LCD display, direct display of volt-ampere curve when testing, intuitive and convenient. With its own micro printer, it can print test data conveniently.
7. Digital keyboard is used to facilitate digital input.
8.With large capacity memory, it can store 100 sets of test data .
9. S232 communication interface, can connect to the computer for testing; test data can also be uploaded to the computer edit and save.
