Clearance and Creepage Distances: Rules and Calculation
Clearance and creepage distances are vital considerations in the design of safe and reliable electrical equipment. By understanding the factors that affect these …
The working clearance in front of the equipment on which you''re working is also dependent on the composition of the facing wall and whether it houses live electrical parts. As you''ll note in the Table, there are three conditions noted for two voltage levels 150V or less and 151V to 600V-to-ground.
This guide, covering three-phase ac systems from 1 kV to 800 kV, provides recommended electrical operating, safety clearances, and insulation levels in air-insu.

High voltage circuits can discharge across a gap, the gap can be through the air or across a surface. Creepage: distance between two conductors on the surface. Clearance: the distance between two conductors through the air. Hence, often just called creepage and
The electrical design of a battery covers a wide array of topics. We will start simple and gradually add to the complexity and depth. The schematic shows 3 cells in series, hence 3S. This would be written as 3S1P. If the nominal voltage of a single cell is 3.6V then
