For Elektrárny Opatovice, a.s., we have been performing long-term diagnostic measurements of insulating oils in the installed equipment. Additionally, we monitor the quality of SF6 gas in circuit breakers and detect ozone in the cooling air of turbogenerators. In recent years, we have also worked on the planned replacement of older transformers with new units manufactured by SGB. We performed control measurements of the oil filling during commissioning and at shortened intervals throughout the warranty period. We enabled the operator to continuously monitor changes and ensure the safe operation of newly commissioned equipment.
