The KDZK-F Generator Rotor AC Impedance Tester is a specialized instrument designed to detect inter-turn short circuits in generator rotor windings. It can automatically or manually (in single or dual direction) measure key parameters of the rotor winding, including voltage, current, impedance, power, and phase angle.

Key Features and Applications:

• Comprehensive Testing: Measures AC impedance and characteristic curves of synchronous generator and asynchronous motor windings under static conditions.
• User-Friendly Operation: Features a rotary knob for easy and convenient control.
• Flexible Measurement Modes: Offers both rapid automatic measurement and flexible manual selection modes.
• Intuitive Interface: Equipped with a large-screen Chinese menu display that shows test data and curves in real time.
• Data Management: Stores test data and is equipped with a built-in mini printer for immediate printing of results and characteristic curves.
• Enhanced Safety: Automatically adjusts protection thresholds based on test parameters to ensure equipment safety.
• Multi-Function Capability: Can also perform open-circuit and short-circuit tests on single-phase transformers, as well as volt-ampere characteristic tests on voltage/current transformers and arc suppression coils.
