The standard specifies safety requirements for power electronic converter systems (PECS) and equipment. It specifically focuses on high-voltage power electronic converters with rated system voltages from 1,000 V AC or 1,500 V DC up to 36 kV AC or 54 kV DC .
Establishes rigorous requirements for clearance and creepage distances to prevent electrical breakdown. Iec 62477-2 Pdf
One of its most significant contributions is the introduction of arc-fault rating labels and testing procedures for PECS, drawing from existing switchgear standards. and tidal power conversion systems.
