Partial Discharge-Free Power Supply FAQ
Key answers for transformer manufacturers, test laboratories and engineering teams evaluating a variable-frequency AC power source for partial-discharge and induced-voltage testing.
What is a partial discharge-free power supply?
A partial discharge-free power supply is a variable-frequency AC test power source used in transformer test arrangements that require controlled voltage, frequency, waveform and electrical isolation.
SDACME equipment is intended to provide the excitation power required for transformer partial-discharge and induced-voltage test applications, with the final configuration selected around the required test duty.
Is a partial discharge-free power supply the same as a partial-discharge detector?
No. The power supply provides the AC excitation source; the partial-discharge detector or measurement system performs the actual PD measurement.
In a complete transformer test arrangement, the power source, measurement equipment, transformer connections and other test components work together according to the selected test method.
What capacity range is available?
The stated SDACME partial discharge-free frequency converter series covers a capacity range of 5 kVA to 2000 kVA.
Final equipment capacity is selected from the complete transformer test requirement rather than transformer rated capacity alone.
What output voltage and frequency are available?
The reference electrical configuration specifies an output-voltage range of 0–1000 V line-to-line and an output-frequency range of 45–200 Hz.
Final electrical interfaces and required operating conditions are reviewed against the selected equipment configuration and the intended transformer test.
What transformer tests can the power supply support?
The primary applications are transformer partial-discharge testing and induced-withstand-voltage testing.
The technical solution also identifies applicable power-supply use for selected transformer no-load loss, load and temperature-rise test duties.
- Partial discharge testing
- Induced withstand voltage testing
- No-load loss testing
- Load testing
- Temperature-rise testing
Why does the test power source matter in transformer partial-discharge testing?
The excitation source establishes the electrical conditions applied to the transformer during the test.
Output waveform, voltage and frequency stability, electrical isolation and output conditioning are therefore important considerations when selecting power equipment for a sensitive transformer test arrangement.
What information should I provide for configuration and quotation?
Start with the transformer information, intended test duty and the required electrical conditions.
- 测试类型
- 变压器的额定容量
- Transformer voltage level
- Available input voltage, frequency and phase
- Required output voltage
