Introduction
The CT/PT polarity and ratio tester is a versatile instrument used for routine testing of current and potential transformers in substations, switchgears and power plants. It can accurately measure turns ratios, check polarity markings and detect any ratio errors in current and potential transformers of various types and ratings. 

Features
• Automatic or manual ratio measurement of CTs and PTs up to different voltage and current ratings  

• Phase displacement and ratio errors indication

• Polarity marking verification through simple go/no-go testing

• Easy-to-read LCD display of test results and parameters 

• Compact, lightweight design for convenient field use


Applications of CT/ PT Analyzer:
1. CT nameplate check
2. CT parameters check in work burden
3. CT transient parameters analysis
4. CT ratio and phase error calibration
5. PT routine test
