Amendment 1 - Rotating electrical machines - Part 18-42: Partial discharge resistant electrical insulation systems (Type II) used in rotating electrical machines fed from voltage converters - Qualific

This standard provides guidelines for the assessment of electrical insulation systems used in rotating motors supplied by voltage converters. It focuses on the evaluation of these systems to prevent partial discharges, which can lead to insulation degradation. The document outlines specific test procedures and criteria to ensure the reliability and performance of insulation systems under operational conditions. It covers the requirements for testing and the interpretation of test results. The standard is applicable to motors that operate in environments where voltage converters are used, and it aims to establish a consistent approach for testing and certification. The content is structured to support manufacturers, testing laboratories, and users in ensuring compliance with established safety and performance standards.
