Power System Testing and Electrical Compliance in Central Texas

An arc flash risk assessment calculates the incident energy at electrical equipment and determines the protective measures and labeling required. Under NFPA 70E it is necessary for worker safety wherever people interact with energized equipment, and OSHA enforces the underlying safety requirements. Comp-Utility performs the study and provides updated arc flash labels and documentation.

NFPA 70B covers electrical equipment maintenance, establishing how and how often to maintain and test systems. NFPA 70E covers electrical safety in the workplace, including arc flash protection and safe work practices. They are complementary: 70B keeps the equipment healthy, and 70E keeps the people working on it safe. We support compliance with both.

Cost depends on the size and complexity of the electrical system, the number of equipment locations, and the condition of existing documentation. We do not publish prices because each facility is different. Request a quote at sales@comp-utility.com and we will scope the study to your one-line and equipment count and provide a clear proposal.

Protective relay testing verifies that the relays which detect faults and command breakers to trip are calibrated and coordinated correctly. Properly tested relays isolate a fault to the smallest possible area, protecting equipment and limiting outages. Comp-Utility tests and, where needed, recalibrates relays so your protection scheme performs as designed.

Acceptance testing, often following NETA standards, is performed on newly installed equipment to confirm it was installed correctly and is ready to energize safely. It catches shipping damage, installation errors, and out-of-spec components before they cause a failure in service. Comp-Utility performs acceptance testing as part of installation and commissioning projects.

UPS capacitors and cooling fans are wear items with finite lives, commonly replaced on a manufacturer-recommended interval of several years depending on the model and operating conditions. Replacing them proactively prevents a capacitor or fan failure from taking the UPS offline. We track these intervals as part of a UPS preventative maintenance program.

Yes. Infrared thermography is performed on energized equipment under load, so there is no shutdown. The thermal scan reveals hot connections and components that indicate developing problems. Because it is non-intrusive and predictive, it is one of the highest-value tests for catching issues early, and it is commonly done annually.

Yes. Every test and study comes with documented results, including thermographic images, test values, arc flash calculations and labels, and recommendations. These records support NFPA 70B and 70E compliance and satisfy auditors, insurers, and authorities having jurisdiction. Good documentation also builds the trend data that makes predictive maintenance effective.
