APPLICATIONS
|
|
They
perform spot tests, step-voltage tests, and dielectric absorption tests for
the
|
|
following
applications:
|
|
Acceptance testing at an installation to check
conformance to specifications.
|
|
Routine preventive/ predictive maintenance
testing after installation.
|
|
Quality assurance testing as part of the manufacturing
process.
|
|
Diagnostic testing to isolate faulty
components for repair.
|
|
Contamination testing of service aged
insulation.
