Natural ester filled transformers, having a high thermal class of solid and liquid insulation, can operate at temperatures up to 20°C higher than mineral oil equivalents; thus, holding additional loading capacity without losing life expectancy. An A

The limited loadability of mineral oil filled transformers leads the users to select the transformer size necessary to meet the required peak demand; this causes the nominal rating to be higher than necessary for the typical demand resulting in trans
