Repair Of Power Transformers

The rapid growth of the capacity of power stations and supply networks and their integration into power systems by means of long-distance high- and super-high-capacity transmission lines require reliable and uninterrupted operation of every piece of electrical equipment power transformers included. On its way from the generating station to the consumer electric power is transformed several times. Today when hardly a single electrical installation can do without a power transformer the uninterrupted operation of the transformers whose total capacity is several times the installed generating capacity cannot be overestimated. Low- and medium-capacity transformers are usually repaired at specialized works while high-capacity ones directly on site. Some transformer parts are repaired at transformer-building works. This book outlines the amount of technical knowledge necessary for electricians specializing in transformer repairs and is intended for training at vocational schools or on the job.
