*) Primary – Core = 10.4m / Secondary – Core = 0.2 mm.
Transformer core is regarded as secondary part. Secondary winding to core distance is 0 mm.
Therefore shortest clearance & creepage distance is considered to measure from core to
primary
winding.
**) Primary – Core = 5.4 mm / Secondary – Core = 1.9 mm.
Transformer core is regarded as secondary part. Secondary winding to core distance is 0 mm.
Therefore shortest clearance & creepage distance is considered to measure from core to
primary
winding.
