Association of Polish Consultants An important aspect of the work of the power system consists in the proper management of transformers maintenance, aimed at maintaining their high reliability and reducing breaks in the electric power supply in compliance with the requirements of the Energy Law act. Any activities related to the management of transformers maintenance should be undertaken not only with regard to the consequences of natural (ordinary) operational and disturbance conditions, but above all they should determine the procedures of deliberate and intentionally executed management of the operating staff. The above activities, on the one hand, concern the different issues associated with the operation of transformers and, on the other, take into consideration various preventive procedures and diagnostic tests the purpose of which is to keep transformers in the state of normal operation. Their accomplishment requires modern methods of research, unambiguous hints concerning procedures in disturbance events and information enabling to formulate correct conclusions and recommendations. The above mentioned issues were the topic of the conference. The conference was granted the status of regional CIGRE conference.
