Instrument Transformer Characteristic Tester

Being a leading and competent business entity we are engaged as manufacturer supplier and exporter of Instrument Transformer Characteristic Tester in Yangzhou Jiangsu China.

Introduction:
JYH-B instrument transformer characteristic tester can measure the turns ratio polarity and volt-ampere characteristics of the current transformers and voltage transformers. It has large power regulating transformer ste-p-up transformer and current-up device inside. The tester is widely used in the routine test of voltage and current transformers.

Features
1)The test voltage and current can be set the tester will automatically increase the voltage and form the volt-ampere characteristic curve;
2)Ability to be connected with an external ste-p-up transformer with output voltage upto 4kV and current upto 1.5A which can test current transformers upto 500kV 1A;
3)Big LCD shows the volt-ampere curve;
4)With micro-printer to print out the test data;
5)With numbers keyboards easy operation;
6)100 test data storage;
7)RS232 communication port can be connected to computer test data can be upload to the computer for edit or save.
Technical parameters
1)Output voltage and current of Inbuilt ste-p-up transformer:0~2500V0~20A;
2)Load range:1A/2500V
