The course of maintenance of medium and high voltage rotating electrical machines, held by Hara Engenharia in partnership with Nishi, is with registrations open for the class that will be held from October 2nd to 6th, 2023 in Londrina-PR. The course aims to present and discuss the problems of operation and maintenance of rotating electrical machines, going through specification, manufacturing process, failure mechanism, off and on-line tests, inspections in each vital part of the generator, mainly stator and rotor. Instructor Takao Paulo Hara is a consultant in the area of operation and maintenance of rotating electrical machines and conducts research in the area of materials and repair techniques for rotating electrical machines. Hundreds of engineers, technicians, production and maintenance supervisors have already participated in this course, whose mission is to operate and maintain rotating electrical machines (motors and generators) maximizing availability and reliability with adequate costs, respecting the health and safety of employees and also the company’s environment.

PROGRAM:

• Review Theory of rotating electrical machines;
• Technology and state of the art of rotating electrical machines;
• Stator failure mechanism and repair. In each mechanism, the process, root cause is discussed,
  symptoms and remedies are discussed;
• Rotor failure mechanism and repair. In each mechanism, the process, root cause, symptoms and
  symptoms and remedies are discussed;
• Mechanism of core lamina insulation failure. In each mechanism, the process is discussed,
  root cause, symptoms and remedies are discussed;
• General principles of testing and monitoring;
• Off-line testing of the rotor and stator windings. In each test, theory and purpose are discussed,
  method and interpretation are discussed;
• Online testing or monitoring of the rotor and stator winding. In each test or monitoring,
  principles and interpretation are discussed;
• Core tests. In each test, theory and purpose, method and interpretation, test
  test method and interpretation are discussed;
• Factory and field acceptance tests of new winding. Pre-qualification tests are discussed,
  factory and field tests of rotor, stator and core windings are discussed;
• Maintenance strategies. Maintenance options (corrective, preventive and predictive) and inspection for various
  and inspection for various rotating electrical machines.

PRACTICAL EXERCISES:

During the course practical exercises may be conducted with the problems brought by the participants. Therefore, students should bring problems that they have experienced and that have not yet been adequately solved in their company. Some tests will also be performed on insulation systems and/or winding of medium or high voltage motor/generator with a workload of 04 hours.
