Medium- and high-voltage electrical equipment must undergo rigorous testing to ensure safety, reliability, and compliance with international standards. These tests include dielectric, mechanical, short-circuit, and thermal evaluations, performed in laboratories equipped with advanced facilities for high-voltage and high-power applications. Conducting such tests in ISO/IEC 17025-accredited laboratories guarantees that results are valid and internationally recognized.
What tests are required for MV and HV electrical equipment?
Testing of medium- and high-voltage equipment typically includes insulation tests, internal arc resistance verification, temperature rise assessments, and mechanical endurance checks according to IEC 62271 and IEC 60060 standards. These procedures confirm that components can operate safely under extreme electrical and environmental conditions, maintaining performance and reducing operational risks.
