The Electrical Testing Company, LLC

Comprehensive electrical acceptance and diagnostic testing to verify that systems are installed correctly and perform according to design specifications prior to startup.

• Acceptance Testing

  Physical inspection and testing to ensure electrical equipment and systems are fully operational and meet design criteria before commissioning.

• Cable Insulation and Over-Potential Testing

  Insulation resistance and very low frequency (VLF) over-potential testing for low and medium voltage cables to verify dielectric integrity.

• Grounding System Testing

  Earth ground resistance measurements using soil resistivity, selective, stakeless, or fall-of-potential testing methods.

• Motor Control Center Testing

  Testing and inspection of motor starters, controllers, and circuit breakers within MCCs to ensure reliable operation.

Scheduled inspection, testing, and maintenance programs designed to optimize asset efficiency, increase equipment lifespan, and reduce unplanned downtime.

• Maintenance Program Planning

  Tailored maintenance planning and scheduled interventions for critical electrical assets to prevent failures.

• Switchgear and Substation Maintenance

  Visual inspection, specialized cleaning, and insulation testing for low, medium, and high voltage substation and switchgear assemblies.

• Transformer Maintenance and Fluid Analysis

  Preventative maintenance and periodic insulating fluid sampling to identify faulty combustible gases and potential winding failures.

• Infrared Thermographic Inspection

  Predictive thermographic scanning of electrical systems to identify abnormal relative thermal emissions and detect hidden faults early.

• Protective Device and Relay Testing

  Calibration and testing of protective relays, ground-fault protection systems, and ground-fault circuit-interrupters.

• Circuit Breaker Testing

  Electrical and mechanical testing of low, medium, and high-voltage circuit breakers, including vacuum circuit breakers.

• Critical and Emergency Power Maintenance

  Inspection, testing, and load bank testing for standby generators, automatic transfer switches, and uninterruptible power supplies.

Analytical and diagnostic engineering studies to verify electrical system capacity, enhance workspace safety, and ensure regulatory compliance.

• Field Evaluation

  Third-party evaluation and certification of unlisted, modified, or red-tagged electrical equipment to meet local codes as an IAS-accredited Field Evaluation Body.

• Arc-Flash Hazard Analysis

  Engineering calculations to determine incident energy exposure, establish safety boundaries, and define proper protective gear requirements.

• Short-Circuit and Coordination Studies

  Analytical evaluation to ensure protective devices are properly set to isolate faults quickly and maintain system reliability.

• Load Flow and Load Recording Studies

  Feeder demand recording and voltage drop analysis to verify capacity and ensure safe margins prior to adding new equipment.

• Power Quality and Harmonic Analysis

  System monitoring of sags, swells, and waveform distortion to identify sources of interference and optimize system design.

• Specialized Engineering Studies

  Transient stability, voltage imbalance, power-factor, and grounding grid design studies based on IEEE standards.

• Single-Line Diagram Development

  Drafting and updating of accurate schematic diagrams representing a facility's entire electrical distribution system.
