Wireless Sensor Networks and the Impact on HVAC Monitoring

Traditional building automation systems have often relied on a relatively sparse network of wired sensors to monitor temperature, humidity, and perhaps a few other basic parameters. Wireless sensor networks are disrupting this model, enabling the deployment of far denser arrays of sensors,...

Beyond Basic Sensors in Smart Lighting

In the realm of building automation, lighting control has evolved from basic on/off functionality to sophisticated systems capable of responding to detailed environmental and occupancy changes. Advanced sensors play a pivotal role in this evolution, enabling smarter, more energy-efficient, and...

Arc Flash Training

Arc Flash Mitigation in LV Systems

A common misconception within the electrical industry is that low-voltage systems (typically operating at 600V or lower) pose a lesser arc flash risk than their higher voltage counterparts. While the potential incident energy may be lower in some cases, underestimating the hazards present in...

Arc Flash Analysis: The Hidden Costs of Non-Compliance

Arc flash hazard analysis is a critical safety requirement in managing electrical risks in the workplace. It involves a systematic study to identify potential arc flash hazards and implement safety measures to protect workers and equipment. Compliance with standards like NFPA 70E and IEEE 1584 is...

Electrical Grounding and the Weather

How resistance testing is affected by the elements BY JEFF JOWETT, Megger Ground resistance testing is affected by the weather as much as any common electrical test—and sometimes even more so. Both the instrument and the test item are affected. With ground resistance testing, the test item is not...

The Art of Ground Testing

Correcting the misconceptions of ground testing BY JEFF JOWETT, Megger Ground resistance testing is sometimes described as an “art”, and indeed something can be said for that description. Familiarity with the basic issues and common problems, however, can take much of the “art” out of it...
