LFD usually reduces total downtime, especially for large power transformers. Because heating is generated directly in the windings, the drying phase is much faster than in hot-air or oven methods for thick insulation. In many cases, drying time is shortened from weeks to several days, and there is no need to remove and transport the active part to an external oven. The trade-off is that setup and monitoring are more specialized, but overall outage time is typically significantly shorter and more predictable with LFD.
