Conformity Assessment for LV products
​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 […]

Optical PD detection in high voltage cable accessories
Optical partial discharge detection is a new method to perform diagnosis of the insulation system detecting optical signals which are coming up at the same time.This method does not work with the electrical signals which are caused in case of partial discharges though. On the basis of this different physical process, external electrical noise can […]
