As-found insulation and contact
resistance tests
As-found tests verify the integrity of the
circuit breaker insulation system. Megger* or
insulation resistance tests and contact-
resistance tests conducted on equipment
prior to installation provide a basis of future
comparison to detect changes in the
protection afforded by the insulation system,
and in the integrity of the current carrying
path. A permanent record of periodic as-
found tests enables the maintenance
organization to determine when corrective
actions are required by watching for
significant deterioration in insulation
resistance, or increases in contact resistance.
