What a surge test evaluates
A surge test applies a fast electrical impulse to a winding and evaluates the resulting waveform. Changes in the waveform can reveal insulation weaknesses that are not visible through low-voltage resistance checks alone.
The useful question is not whether every motor needs the same test. It is which winding, operating condition, failure mode, and decision the test must support.
Comparison of windings or phases under a defined test plan
Use this input to narrow the current fit before a recommendation is treated as final.
Repair, maintenance, production, and laboratory applications
Include this requirement in the application review and current configuration check.
Application path
Build the test plan before selecting equipment
A defensible plan starts with the asset, insulation system, service condition, applicable procedure, and acceptance criteria. MDS can help map those inputs to an appropriate Schleich test path.
Define the test object and operating context
Use this input to narrow the current fit before a recommendation is treated as final.
Confirm the governing procedure or standard
Use this input to narrow the current fit before a recommendation is treated as final.
Set qualified acceptance criteria
Include this requirement in the application review and current configuration check.
Document connections, settings, and results
Clarify how results will be reviewed, stored, and used.
Current next step
Confirm the application with MDS.
Share the equipment, process, test question, environment, and timing so MDS can route the request to a current product, method, service, or support path.
