Abstract :
Oil filled power transformers in Manitoba Hydro have free breathing conservators. Some of the insulating oil purchased since the late 1970s has had a shorter service life than oils that were purchased earlier. Corrective and preventive measures are discussed. Evaluation of and service applications with a new isoparaffin oil are reported
