Current Transformer Potential Transformer Test Instrument CT PT Tester
The CT PT tester is an electronic instrument used to calibrate and verify these transformers, providing accurate and automated testing capabilities for current and voltage transformers. The CTPT transformer is a key component that steps down high currents and voltages to safer levels for measurement, protection and control purposes. It has a DSP data acquisition system that can complete data acquisition for variable frequency power supply control and test processes.
* Higher accuracy and test stability.
* The tester has a wider range of functions.
* Larger storage capacity, more than 5000 groups.
* Simple operation, data analysis, storage and interface display are all completed by the industrial computer system.
