Soaking a transformer before putting a load on it is Definitely old school. Transformer Mfg.'s recommended energizing with voltage even at 50% of rated Voltage @ 50/60 Hz for 24 hours .The 60 Hz allowed the oil to saturate all the paper insulation in the windings. With out doing this the paper would burn @ full load which really would de rate the Transformer & contaminate the oil.
