The objective of this course is to outline the suggested work procedures that are typically performed for transformer preventive maintenance. The suggested procedures presented in this course do not pertain to the major overhaul and transformer repair. Nevertheless, many procedures completed during routine maintenance and transformer major overhaul may be the same. The maintenance routines discussed in this section can be applied to a transformer that has not reached an advanced deterioration stage. Also, these suggestions are written for the average circumstances under which the transformer is required to work. It is further implied that all staff involved with the maintenance are adequately trained and have transformer maintenance experience. The suggested practices presented in this course are similar to those that manufacturers suggest for their equipment. If detailed instructions are needed, the student needs to consult manufacturer manuals. Transformer preventative maintenance involves routine inspection, adjustment, testing, minor fixes, and special handling instructions. Also, the trouble-free service of the equipment over its life depends on proper installation, operation, and maintenance. This course is suitable for engineers with a desire to understand the fundamentals of power transformer maintenance. Presented details cover issues related to transformer installation, acceptance and different maintenance philosophies that are applicable to different transformer types. Upon successful completion engineers will be able to address various transformer maintenance terms, procedures that are in line with relevant, international standards and best industry practices that are adopted by transformer industry.
