Xzh Test Supply Transformer CT/PT Analyzer Single Phase Excitation Ratio Testing
XHTX201D CT/PT ANALYZER is mainly used for field testing of P class CT and PT. The test
items mainly include excitation characteristic, transformation
ratio, polarity, Degauss, 5% and 10% error curves, secondary
circuit check, withstand test of power frequency alternating
current and secondary load. Adopt LCD, self-equipped minitype
printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.
Main features
Support for detecting CT and PT both
- All inspection items can be completed in a single instrument without external auxiliary equipment.
- With intelligent controller, which is easy to operate.Large screen LCD, graphdisplays the ports.
- Automatically give 5% and 10% error curves.
- 3000 sets of test data can be saved and will not be lost even after power failure.
- Support U disk save the data, can be read through a standard PC, and generate a WORD report.
- It's compact and lightweight, its weight is less than 22Kg, very good for field testing.
