The instrument transformer test sets is a full automatic microprocessor-based integrated test set. It can perform tests of current transformers and potential transformers, such as excitation, ratio, winding polarity, ratio and phase angle error, etc.
It automatically raises and lowers the excitation test voltage without any operator intervention, with more than 1200VAC excitation test voltage available; it can easily perform tests on large current transformers.

Main Features of Instrument Transformer Test Sets
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 16Kg.
5) Built-in large size thermal printer.
6) The instrument transformer test sets has a flash memory to store more than 1000 units test data.
7) USB computer interface.
8) Large size LCD display, menu displaying and rotate mouse.
