How can Electrical Surveys help?
Infrared thermography can be used to perform predictive maintenance inspections on electrical equipment. Our infrared surveys are able to see problems before component failure occurs, preventing costly damage to the component, safety hazards, and production downtime.
Switchgear Testing
The most popular and widely used application of infrared thermography is electrical switchgear testing. Daily, the electrical switchgear in thousands of buildings are checked by thermographers all over the country. Electrical Infrared has proven to be a vital part of any facility manager’s preventative/predictive maintenance (P/PM) program.
Electrical distribution equipment that should be routinely checked
- Utility substations, transformers and feed poles
- Main incoming services, plant main knives, capacitor banks, etc
- Main switchboards and disconnects
- Main distribution panels and main disconnects
- Uninterruptible power supplies
- Generator controls and transfer switches
- Main I-Line panels
- Lighting and receptacle panels
- Disconnects and combination starters
- Service disconnects for motors
- Machine control panels
Data Center Testing
We understand that downtime at Computer Centers is not an option. We also know that tests can only be carried out safely at certain times, which is why our thermographers are available 24 hours a day/365 days a year. Our infrared inspections of electrical and mechanical systems support the continuous operation of these centers.
Computer equipment and related systems that should be routinely inspected
- UPS (Uninterruptible Power Supply) systems
- ATS (Automatic Transfer Switch) systems
- Main Switchgear systems
- Computer and Server Systems
- Generator systems
- Battery systems
- Cooling systems
How does it work?
Excess resistance on an electrical apparatus indicates electrical faults, such as loose connections, overloaded or imbalanced circuits, faulty breakers, damaged switches, faulty fuses, a wide range of other unwanted electrical conditions.
Faulty electrical components will heat up before they completely burn up. Thermography is used to see the excess heat (resistance) so that problems can be found and maintenance personnel can act to correct the problem before the component fails.
