Measuring clearance
- Jun 29, 2018 -

Based on the measured operating voltage and insulation level, the distance can be determined by looking up the required clearances.

GB 8898-2001: The main factors for consideration of clearances are the components of the working voltage, voltage, and voltage that are galvanically connected to the mains supply in the range of 220-250 V. These values are equal to those corresponding to the peak voltage of 354 V: Basic insulation 3.0 Mm, reinforced insulation 6.0mm.
