Assessing Generator Condition in South Africa

摘要

Regular inspection, testing, and trending of results are useful in detecting any developing problems in generators and preventing expensive machine failure. Electrical tests of the rotor and stator, such as insulation resistance and tan delta, as well as stator core tests, are some of the most common tests used in South Africa. Many tests are available to help operators detect developing problems in large hydro generators. Operators can perform some of the more common tests as a precaution to catch small problems before they grow or to determine how to proceed in the event of a machine failure. These tests include stator and rotor tests, as well as stator core tests. Regular testing and trending of the results are vital to predict and be able to prevent expensive machine failure.
