NAJZK Automatic Generator Rotor AC Impedance Test Device
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
