Product Description
Product Description

The Power Transformer Test Bench is designed for comprehensive electrical performance testing of power transformers.

The system focuses on several key parameters that engineers need to verify before a transformer leaves the factory or enters service.

Main Test Items
  1. Turns Ratio Test

    Verifies the actual transformation ratio and detects ratio deviations.

  2. Vector Group Test

    Identifies the transformer connection group and phase relationship.

  3. DC Resistance Test

    Measures winding resistance and evaluates conductor and connection conditions.

  4. No-Load Test

    Measures no-load loss and no-load current under specified excitation conditions.

  5. Load Test

    Measures load loss and short-circuit impedance.

  6. AC Withstand Test

    Evaluates insulation withstand capability under the specified AC test voltage.

These functions correspond closely with the core functions described for current transformer comprehensive test benches.

Why Are These Tests Important?
  • Turns ratio: Confirms winding ratio and tap position performance.
  • Winding resistance: Helps identify abnormal resistance caused by winding connections, joints or tap-changer contacts.
  • No-load loss: Provides information about transformer core performance.
  • Load loss: Helps evaluate winding and additional losses.
  • Short-circuit impedance: Provides important information for transformer performance and system calculations.
FAQ

Q: What is the difference between no-load and load testing?
No-load testing evaluates transformer behavior when the secondary side is open, while load testing evaluates losses and impedance under a short-circuit test condition.

Q: Why is short-circuit impedance important?
It is an important transformer performance parameter and affects voltage regulation and parallel operation characteristics.

Q: Can the test bench automatically correct load loss?
Depending on the software configuration, measured results can be converted according to the specified reference temperature and test requirements.

Q: Can the system be used for transformer FAT?
Yes. Factory acceptance testing is one of the major applications of comprehensive transformer test systems.
