ELECTRICAL INFRARED INSPECTION

 

 

 

Do we need an electrical infrared (IR) inspection?

All electrical equipment will give off some amount of heat during their operation. Normally, this is manageable and does not cause any problems. For electrical distribution systems, the key failure mechanisms are faulty connections, undersized equipment, and wear and tear on protective devices. In all these scenarios before a minor problem manifests itself into downtime and catastrophic failure, hot spots are produced which can be identified in advance and corrective actions can be taken.

Electrical infrared (IR) Inspection service

The goal of every electrical infrared (thermal) inspection is to survey designated electrical equipment in order to pinpoint defective components and elevated temperatures within your power distribution system. If unfound or untreated these thermal “hot spots” can cause- potential fire, explosion, or electrical service interruption threats. Thermal hot spots are typically caused by unbalanced or overloaded electrical circuits, loose connections, or broken equipment. These conditions are often overlooked during routine evaluations of facilities and can result in the release of heat that will be visible only through infrared thermography detection services.

Benefits

A typical electrical infrared survey can in a net a savings from $10,000 to $20,000, depending on the number and category of anomalies found. In addition to the direct financial savings, valuable time is saved by incorporating an annual infrared electrical survey into your PM program. Providing accurate information regarding the integrity of your electrical system’s components cuts down on maintenance time, prevents costly replacements and can eliminate unforeseen outages and downtime. An infrared (thermal) electrical inspection survey can help:

Nowadays, technologies are being improved, usability (user-friendliness) is being enhanced, product features are being added and prices/performance points are becoming more attractive.

  1. Maintain the integrity of your facility’s electrical system
  2. Reduces electrical fire hazards
  3. Provide uninterrupted power to tenants/clients/employees
  4. Detect faulty connections/overloaded circuits
  5. Provide a snap shot in time of the condition of your mechanical systems, motors, bearings, etc.
  6. Preventative or predictive maintenance programs save money by reducing:
    a. pre-mature equipment failure
    b. emergency overtime
    c. overnight shipment of parts
    d. insurance premiums (many insurance companies give discounts for performing regular infrared inspections)
    e. loss of revenue due to downtime

Work process

Our certified thermographers quickly and non-destructively pinpoint electrical and mechanical problems that can’t be seen with the naked eye, such as loose connections, faulty breakers, disconnects, overloaded circuits, imbalanced loads, weak motor windings and bearings, and much more. Detection of and imaging of thermal problems are done using modern thermography cameras. During the electrical infrared survey, our team will generally inspect the following equipment, but can provide inspection and imaging on any electrical or mechanical components according to your specification.

  • Switch Gear
  • Transformers
  • Service Disconnects
  • Transfer Switches
  • Busways
  • Motors / Pumps / Bearings
  • Start from the lamp / heating system
  • Motor Control Centers
  • Breaker Panels
  • Starters
  • UPS Equipment
  • Chillers and Roof Top
  • HVAC Equipment
  • VFDs

Deliverables

Nhat Ha Electric’s electrical infrared reports are concise and to the point, making anomaly location easy to determine and facilitate repairs. Your report will include: a detailed easy-to-read inspection report including:

  • Complete list of equipment inspected
  • Written narrative of the survey
  • Report form for every anomaly detected during the inspection.
  • A report sheet accompanies each problem which includes:
    • Digital visible light photograph & color thermogram (infrared) picture
    • Severity category of problem
    • Potential cause of problem
    • Physical location of problem
    • Problem area temperatures
