MODEL HUAC-5315
Generator Rotor AC Impedance Tester
Measures AC impedance and characteristic curves of generator rotors; also for single-phase transformer no-load and short-circuit tests. 600 V, 120 A, printer.
- AC impedance and characteristic curves of all generator rotors
- Also for single-phase transformer no-load and short-circuit tests
- Volt-ampere characteristics of CTs, VTs and arc suppression coils
- Automatic over-voltage and over-current protection settings
- Large graphic LCD with live data and curves
- Built-in printer; RS232 transfer to PC software for reports
- English user interface; English operating system available
Overview
The HUAC-5315 measures the AC impedance and impedance characteristic curves of generator rotors, automatically or manually. Voltage, current, impedance, power and frequency are captured, displayed, stored and printed, with the curve scaled automatically for clear reading.
The same instrument performs no-load and short-circuit tests on single-phase transformers and volt-ampere characteristic tests on CTs, VTs and arc suppression coils. Over-voltage and over-current protection limits are set automatically from the test parameters.

Frequently asked questions
Why measure rotor AC impedance?
Inter-turn short circuits in a generator rotor winding reduce its AC impedance. Comparing impedance curves with earlier results reveals these faults.
What else can it test?
No-load and short-circuit tests on single-phase transformers, and volt-ampere characteristics of CTs, VTs and arc suppression coils.
How are reports made?
Results print on the built-in printer, or transfer to a PC over RS232, where the software generates editable test reports.
