The High Current Transformer Winding Resistance Tester is engineered for measuring the DC resistance of transformer windings, including large power transformers and low-resistance windings.
A higher test current can help achieve more stable measurement conditions for suitable low-resistance inductive loads and can reduce measurement stabilization time in certain applications.
Different output current configurations — such as 10A, 20A, 40A or 50A — may be available depending on the instrument model.
The instrument is suitable for transformer factories, power utilities, electrical testing contractors and large transformer maintenance departments.
Do not select a tester based only on its maximum current. The suitable current also depends on winding resistance and transformer specifications.
The measurement range should cover the expected winding resistance values at the selected test current.
Large transformer windings are inductive loads. Stabilization time and discharge management should be considered.
Confirm the rated duty cycle and cooling requirements for the expected testing workload.
Back-EMF protection, automatic discharge and clear discharge indication are important safety-related features.
Higher current configurations may be more suitable for certain low-resistance winding measurements. The correct rating depends on the transformer and measurement requirements.
Many instruments offer multiple current ranges, allowing different winding resistance values to be measured. Confirm the measurement range and current selection before purchase.
No. Accuracy depends on the instrument's measurement circuit, calibration, resolution, current stability and measurement conditions.
Measurement time depends on transformer size, winding inductance, test current, resistance stability and test procedure.
Many professional models include automatic discharge and discharge alarms. Confirm the exact configuration.
Yes. It is suitable for factory inspection when the measurement specifications match the transformer requirements.
