Function:

Measurement of primary and secondary circuit current, transformation ratio, angle error, polarity and phase sequence of current

transformers and potential transformers below 35kV.

Features:

1.Current clamp adopts high performance Permalloy core, magnetic shield and CT digital integrated technology, with strong anti-interference ability, high accuracy for testing. 

2.The primary high voltage clamp adopts innovative automatic plug and pull structure makes it easy to clamp or withdraw the tested wire by pressing or pulling the insulation rod, saving time and convenient. 

3.The primary high voltage clamp adopts wireless transmission mode, transmission distance 100M. 

4.The primary flexible current clamp is especially suitable for small space and flat cable dense places, more convenient and fast for testing. 

5.Data hold function, data storage function, data upload function
