Moisture Prevention Guidelines for High-Frequency Transformers

To ensure safe and stable operation of high-frequency transformers (HFTs), proper maintenance is essential, with moisture prevention being critical. Effective moisture control removes water from insulation materials, increases insulation resistance, and enhances flashover voltage. Note: Transformers above 3kV must undergo mandatory drying. Key moisture prevention factors:

1. Insulation Material
Diffusion coefficient depends on:

• Insulation moisture content

• Temperature

• Ambient air pressure

2. Thermal Energy
Crucial for large HFTs where massive insulation contains significant moisture. Sufficient heat ensures effective dehumidification.

3. Vapor Pressure Differential
Higher differential between internal/external environments accelerates moisture evaporation/diffusion. To increase differential:

• Reduce ambient vapor pressure

• Raise insulation temperature

4. Processing Time
Drying duration depends on moisture content. Optimal process achieves target dryness rapidly. Post-drying moisture-proofing is mandatory.
