Dry Type Transformers Explained | The Electricity Forum Type Transformers "transform" voltage either up to a higher voltage (step up) or down (step down) to a lower voltage. Normally, that transformation takes place when power line transmission voltages (such as 500 kV) are "stepped down" to a much lower level, suitable for use by iindustrial power systems (30 kV) aor residential (120-240V).
