Energy utilities need on-site AC high-voltage acceptance tests on their cable systems and switchgear, in order to ensure the quality of their transmission systems; such tests need to be performed on site with special equipment as well as remarkable measurement technology and diagnosis at voltages of up to 500 kV. Complete acceptance tests such as […]
The recent changes to IEC standard for Low voltage switchgear assembly created a higher demand of tests which earlier were not mandatory. The former IEC 60439 defined indeed two different approaches to compliance: TTA – Type Tested Assembly, an assembly that has been completely type tested and PTTA – Partially Type Tested Assembly, an assembly […]
