Dielectric strength test
The following test setup is used to test the dielectric strength of the insulating coating: A copper ring
is pressed to the top edge of the ring. It touches the ferrite ring at the edges (see diagram).
The test duration is 2 seconds.
Metal poles
Chamfer
Large toroidal cores use thick wires that are partially subjected to high mechanical stress during
winding. This can damage the wire insulation as well as the coating of the cores, thus reducing the
breakdown voltage. To avoid this, EPCOS toroids have a chamfer. This prevents any insulation
damage, and produces uniform coating thickness at the same time.
