Instrument Transformer Test Sets
Description
This instrument is a full automatic microprocessor-based integrated test set. It can perform all the test items of current transformer and potential transformer, such as excitation, ratio, winding polarity, ratio error and phase angle error, etc.
This instrument automatically raises and lowers the excitation test voltage without any operator intervention. With up to 1200VAC excitation test voltage available, it can easily perform excitation tests on very large current transformers.
Main features
1) Full automatic, without any parameter setting
2) Both for CT and PT, up to 20 test items
3) 220V AC input, high safety output
4) Portable, light weight only
5) Built-in large-size thermal printer for site printing
6) Big size flash memory, store up to 1000 units test data
7) USB computer interface
8) Large-size LCD display, menu displaying, rotate mouse
