Transformer PD and Induced Voltage Withstand Test Technical Questionnaire.docx
Multi-application:
PD test, series-resonant test, induce voltage withstand test, grounding test, and transformer loss test, or individually used as high-power mid-frequency signal source
Main Feature:
¡ñ¡¡All PD and induced voltage withstand test of 1000kV UHV & 750kV EHV transformers, and DC converter transformers in China
are completed with the PD-free VF
¡ñ¡¡Power Supplies provided by Haiwo Science & Technology
¡ñ¡¡PD-free VF Power Supply--output power 5kW~1350kW, pure sine wave with less than 1% distortion, and merely PD level less
than 5pC
¡ñ¡¡Parallel compensation method adopted as mid-frequency power generator set
¡ñ¡¡Smaller starting current, lighter, and noise level lower compared to power generator set; self-exciting over-voltage avoided
¡ñ¡¡Linear amplifier matrix composed by power transistors; with switching components not used, the power supplies avoid
high-frequency harmonics and provide pure
¡ñ¡¡sine wave with less than 1% distortion and 5pC PD level
¡ñ¡¡ABB, phoenix, Sanyo, ODU, Suzuki high-quality components applied
¡ñ¡¡Multi-protection: over voltage/current, arcing, zero protection, and so on
¡ñ¡¡Multi-tap exciter transformer for different voltage level transformer test
¡ñ¡¡Multi-tap inductor installed on the anti-eddy-current base, equipped on the test truck for convenient test
¡ñ¡¡Conform to the PD standards IEC 60076-3 & GB 1094.3-2003
