Operating at medium voltage introduces severe risks of lethal electrical shock and arc flash. The standard enforces strict boundaries for:
In many modern applications, IEC 62477-2 is becoming the preferred safety standard because it is more aligned with the latest technological shifts in the "Smart Grid" and renewable energy sectors. How to Obtain the Standard
: Development and certification of high-voltage adjustable speed drives (ASD). Iec 62477-2 Pdf
It is part of the IEC 62477 series, which deals with . While Part 1 covers general safety requirements, Part 2 focuses specifically on traction systems – i.e., power converters used in electric trains, trams, metros, light rail vehicles, and battery-electric or hybrid rail vehicles.
For example, a study by the European Copper Institute found that the implementation of IEC 62477-2 led to a significant reduction in transformer failures and associated costs. The study estimated that the standard had saved the European economy over €100 million in reduced losses and avoided costs. Operating at medium voltage introduces severe risks of
It details exact test setups (e.g., impulse voltage tests, AC/DC dielectric tests, and mechanical impact testing) required by third-party certification bodies like UL, TÜV, or Intertek.
