Condition-based evaluation helps electric utilities decide if and when installed power equipment, such as a power transformer, needs to be repaired, replaced or upgraded to maximise operation and profit. To determine the individual equipment risks and capabilities associated with different power system scenarios, it relies on objective information that can vary from 'crisp' numerical data to vague details expressed in 'natural language'. Utilities can use this method to improve equipment availability and reliability, reduce lifetime costs, and make maintenance and replacement scheduling more efficient.
