When the number of tap steps and tap voltage remain unchanged, the number of tap segments can be increased as appropriate. Reduce the number of tap segments, or increase the number of positive tap segments while reducing the number of negative tap segments; for example, (5%)→2×2.5%, (25%→+3×2.5%, -1×2.5%), etc.
