For High Voltage (HV) winding in small transformers, the cross-over winding is most suitable because:
- Designed for High Voltage: It effectively handles high voltages due to its structure, which reduces voltage stress.
- Economical for Small Transformers: Cross-over winding requires minimal insulation material, making it cost-effective for small transformers.
- Reduced Eddy Current Losses: The winding distributes the current more evenly, reducing eddy current losses.
- Compact and Efficient: It allows for a compact coil design while maintaining good electrical performance.
Additional Information
- Sandwich winding: Used in low-voltage, high-current applications like distribution transformers.
- Continuous disc winding: Suitable for high-voltage, high-power transformers, but not typically used in small transformers.
- Helical winding: Used for medium-voltage, high-current applications, mainly in large transformers.
