Transformer Testing

Transformer testing helps assess electrical performance, insulation condition, and potential equipment deterioration. As part of Predictive Transformer Maintenance, suitable diagnostic tests can reveal changes that require further investigation before they lead to operational problems. Depending on the transformer type and maintenance objective, Transformer Testing may include insulation resistance measurements, winding resistance tests, oil quality analysis, dissolved gas analysis, and other specialised assessments. Interpreting results alongside operating history helps qualified personnel evaluate equipment condition and determine appropriate maintenance actions.
