Insulation coordination for equipment within low-voltage systems - Consideration of high-frequency voltage stress Ingestion-build-115288 DD IEC/PAS 62545 states that1 Scope and object This part of IEC 60664 deals with basic, supplementary and reinforced insulation subjected to high frequency voltage stress within low voltage equipment. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1. It is applicable for the dimensioning of clearances, creepage distances and solid insulation stressed by any type of periodic voltages with a
