Overview

The comprehensive characteristic tester for transformers is designed with reference to standards such as GB1207-2006 and GB 1208-2006, and is used for automatic testing of protective CT/PT. It is suitable for laboratory and on-site testing. It can automatically complete the testing of CT/PT excitation characteristics, CT/PT ratio, CT/PT polarity, CT/PT ratio difference, CT/PT angle difference, CT primary current, CT/PT AC withstand voltage, CT/PT secondary load, and CT/PT DC resistance.

Product Details

Transformer comprehensive characteristic testerMain features

• Support detection of CT and PT

Meet the requirements of regulations such as GB1207 and GB1208

Without the need for external equipment, all testing items can be completed on a single machine, and excitation and variable ratio polarity tests can be completed simultaneously in one test.

Equipped with a miniature fast printer, it can directly print test results on site

Easy to operate with intelligent prompts, making it easier for users to get started. .

Large screen LCD with graphical display interface

Automatically provide CT/PT (excitation) inflection point values according to regulations

Automatically provide 5% and 10% error curves

Can save 3000 sets of test data without losing it after power failure

Supports USB flash drive data transfer, which can be read through a standard PC and generate WORD reports

Small and lightweight ≤ 28Kg, very conducive to on-site testing
