EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62271-301 testing. The IEC EN 62271-301 technical report applies to high voltage switchgear and control assemblies such as circuit breakers, disconnectors and switches. However, its application to other equipment is not excluded. There is no coordination between dimensions and rated normal current.
Recommended dimensions for rectangular HV terminals should be limited by the diameters of the holes and the distances between the holes. The distance between the holes should be applied to the two adjacent holes, both along the apse and along the ordinate.
IEC EN 62271-301 is a technical report published by the International Electrotechnical Commission (IEC) that provides guidance for the design, testing and installation of high voltage switchgear and control equipment. Specifically, it covers the "insulation coordination" of such equipment, which refers to the selection of appropriate insulating materials and spacing of conductive parts to ensure safe and reliable operation.
The report summarizes several factors that must be considered when designing high voltage switchgear and control gear, such as the rated voltage, the type of insulation used, the operating environment, and the probability of various electrical faults. It also provides guidance on testing procedures to verify the insulation coordination of equipment.
In general, IEC EN 62271-301 aims to help ensure the safety and reliability of high voltage switchgear and control devices, which are critical components of power transmission and distribution systems.
