Product introduction 

NAJZK rotor impedance tester is to determine whether the generator rotor winding inter-turn short circuit of the special equipment, can be automatic, manual (unidirectional or bidirectional) measurement of the rotor winding voltage, current, impedance, power, phase angle and other parameters.

Also called name

Generator rotor impedance tester

The Characteristics of the products

◆ Rotate the mouse, the operation more convenient.

◆ Selectable fast automatic measurement and manually select an arbitrary measure in two ways.

◆ large screen English menu interface, real-time display of test data and curves.

◆ store data, comes with micro-printer, real fast print test data and characteristic curves.

◆ automatically adjusted according to the test parameter value protection action to ensure the safety of equipment.

◆ can cater to single-phase transformer no-load, short circuit test and voltage (current) transformers, arc suppression coil volt-ampere characteristic test.
