Medium & High Voltage Testing

Pelican Coast Electric provides professional high voltage electrical testing services for commercial, industrial, and critical power systems throughout Orange County. Our testing services help verify the safety, reliability, and performance of electrical infrastructure before energization and throughout its service life.

Whether you need acceptance testing for a newly installed system or maintenance testing for existing equipment, our team can identify potential issues before they become costly failures.

Unlike testing companies that only provide reports, Pelican Coast Electric can test, diagnose, and repair electrical systems with the same licensed crew. That means faster resolutions, less downtime, and a single point of contact from inspection through repair.

High Voltage Electrical Testing Services

Acceptance and Maintenance Testing

Electrical acceptance testing confirms that your new equipment meets manufacturer specifications before you energize it for the first time. This step prevents immediate failures and validates your warranties. Maintenance testing evaluates your existing infrastructure to catch insulation degradation and connection issues before they cause outages. We recommend maintenance testing approximately every three years to establish a baseline and track the health of your assets over time.

 

Medium Voltage Cable Testing

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.

VLF Testing

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

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.

Hi-Pot Testing

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

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.

OUR PROCESS

We structure our electrical testing process to verify safety upon installation and prevent failures over the lifespan of your equipment. We prioritize schedule coordination with direct contact with GCs and project managers to keep your project moving without delays. Our approach ensures you meet manufacturer requirements and maintain operational continuity.

Step 1

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.

Step 2

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.

Step 3

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

Frequently Asked Questions About High Voltage Electrical Testing

How often should existing equipment undergo maintenance testing?

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.

Because we are a licensed C10 contractor and not just a testing lab, our crew immediately transitions from testing to repairing the fault. We identify the exact point of failure and perform the necessary cable splicing, equipment replacement, or repairs to get your system cleared for energization without delaying your project.
