Non-contact infrared scanning is the most applicable methods for non-destructive, preventative, and predictive maintenance of switchgear. The scanning of the systems fuses, bolted connections, breaker panels, and electrical cabinets can determine if these components require further investigation and prevents impending issues due to overloading. Here at Trace, we use the latest in infrared technology. Our thermography certified technicians can quickly determine if there are any problems, and its cause.
These only a few of the many benefits of Trace’s non-contact infrared scanning:
- Analyze load conditions of switchgear quickly
- Determine loose connections without torqueing
- Non-destructive method for testing cable terminations
Effective grounding is a lot more than a straightforward go/no-go application. The National Electrical Code (NEC) is the basis for the well-known 25-ohm standard. This must, however, not be considered as the be-all and end-all of grounding as it (unfortunately) is often considered. The NEC requirement is fairly forgiving, with the sensible consideration that a technician can not be held accountable for installing an extensive and costly ground grid simply due to the fact that he is cursed enough to be working with a client resting on high resistivity land. Satisfying the Code’s requirement guarantees that there is at least a working ground electrode in place, the structure is not purely “floating,” and a sensible level of lightning protection is in force. The Code’s main concern is electrical safety. This is not meant to ensure functionality. For commercial enterprises, however, performance must rank a close 2nd to safety in terms of the performance of electrical hardware. Merely “meeting Code” can still leave a large gap between nominal and optimum grounding, and this contingency should be checked out to be diminished or eliminated.
