Transtector, PolyPhaser, and our customers deal with lightning and surge protection in our jobs every day, focusing on protecting network equipment. In the lightning season, however, a reminder about personal safety never hurts.
UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD). Surges are rapid increases in voltage and current that can occur on AC or DC power circuits that can damage equipment attached to these circuits. An example of a surge would be a lightning strike on or near exposed power lines. The strike can induce voltages on the power line that can exceed a million volt.
By now, the Smart Grid has become part of our vocabulary, and an ever-growing element in the utilities world. The Smart Grid is the result of the modernization of an electrical network system that’s more than a century old. Digital and analog systems take the place of outdated infrastructure, laying the groundwork for the deployment of emerging technologies and the need for network surge protection to assure reliability.
Global positioning systems are an important part of any RF network. GPS provides timing information that is critical in keeping RF networks synchronized. It is important that GPS receivers be protected from lightning strikes with RF lightning arrestors.
Today’s industrial applications include a broad range of sensitive, valuable and critical electronic equipment, from automation and control systems to instrumentation and LED lighting.
Protecting this equipment from surges, transients and other power anomalies is critical to maintaining performance and minimizing revenue loss from downtime. Transtector Systems and PolyPhaser provide a broad range of surge protection solutions for industrial applications. What strategies are best for this application?
Improper grounding accounts for a large percentage of damage and misoperation of sensitive electronic equipment. Multi-grounding renders equipment susceptible to lightning induced transient over-voltages as well as steady-state noise caused by ground loop currents. These problems can be avoided by implementing a single-point grounding system and following the National Electrical Code.
