Medium voltage cable testing evaluates the insulation integrity of your underground conduit and facility power runs. We use specialized methods to ensure your cables withstand operational stresses and age-related degradation.
Very low frequency (VLF) testing is the standard for medium voltage cables. We apply a low-stress hi-pot at 0.1 Hz to test long cable runs efficiently. This pass or fail withstand test confirms if your insulation can hold the required voltage without breaking down.
Tan delta testing grades cable insulation condition over time rather than providing a simple pass or fail result. Run alongside VLF testing, it measures energy loss to pinpoint aging, water treeing, and contamination before a catastrophic failure occurs.
High potential testing is the core method of insulation withstand testing. We apply voltage above operating levels to verify insulation prevents ground faults. This strict pass or fail test confirms the dielectric strength of your cables, switchgear, and commercial panel upgrades.
Transformer testing evaluates the health and safety of your power distribution units. We check insulation resistance, turns ratio, and winding condition to catch faults early. If we find an issue, our crew transitions directly to providing full electrical transformer repairing services.
Electrical Acceptance Testing
Electrical acceptance testing confirms that your newly installed equipment meets manufacturer specifications before you energize it for the first time. We apply the necessary withstand and diagnostic tests to your cables, transformers, and switchgear. This step prevents immediate failures, validates your warranties, and ensures safe startup for your new construction projects.
Routine Maintenance Testing
Maintenance testing evaluates your existing infrastructure to catch insulation degradation and connection issues before they cause costly outages. We recommend maintenance testing approximately every three years. This schedule establishes a baseline for your equipment and allows our technicians to track the health of your assets over time using methods like tan delta testing.
Same-Crew Repairs
If our testing process reveals a failing asset, we do not hand you a report and walk away. As a C10 Licensed contractor, our crew transitions directly from diagnostics to repair. We address the failure on the spot, ensuring your facility gets back online faster with full accountability.

COMMON QUESTIONS
We recommend maintenance testing approximately every three years. This schedule allows you to track insulation degradation and catch failures before they disrupt your operations.
VLF testing is a pass or fail withstand test that applies stress to the cable to see if it holds. Tan delta testing measures the energy loss in the insulation to grade its overall condition and predict future failure.
A local contractor provides a single-source solution. If the testing reveals a failure, our licensed electricians can repair the issue immediately. Testing labs only provide reports and require you to hire a separate contractor to perform the fixes.
Electrical acceptance testing verifies that newly installed equipment meets manufacturer standards before you energize it. This protects your warranties and ensures safe installation.
