Lightning & Surge Protection Blog
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 Digital and analog systems take the place of outdated infrastructure, laying the groundwork for the deployment of emerging technologies and the need for network surge protection to assure reliability.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?
One of the main issues confronting a small cell deployment is getting permits for the build and having them approved once the build is completed. Once a site has been identified, the permitting process begins. One of the main hurdles for approval of a permit is approval of the BOM that will be used at a small cell site. Electrical safety is a major concern of municipalities. Having a cabinet that is UL 67 Listed will address these safety concerns. This will facilitate in the approval of site permits as well as having them signed off during final site inspection.
The value of surge protection is clear, and not just in communications networks. Industrial applications today utilize high-value equipment with integrated electronics, computers, controls, microprocessors, and other componentry that simply must be protected from power line issues.
FirstNet is the first nationwide infrastructure project dedicated specifically to enhancing public safety through an interoperable broadband communications network for first responders only, and progress is well underway to make this valuable system a reality.
Some time ago while presenting a grounding and protection symposium and explaining the differences between an uninterruptible power supply (UPS) system and a surge protector, an engineer in the back of the room yelled, ”A UPS is not a surge suppressor.” While I gladly accept help from the audience and generally agree with his statement, some types of UPS systems provide isolation from harsh AC or grounding. However, how effective are they really?
Transtector SPD Protects Wireless Radio Equipment from Multiple Surges
Sometimes the effectiveness of surge protection is simple to demonstrate. So is its value.
Transtector Systems recently partnered with FluidMesh, a manufacturer of outdoor wireless Ethernet radio equipment, to surge-test radios, underscoring the importance of high-quality surge protection. The results clearly substantiate the significance of surge protection in today’s network topologies, providing critical protection for high-value transmission equipment.
To adequately address the question of how to avoid—or at a minimum reach—an acceptable level of PIM, consider three key aspects:
As the professional Mobile Communications world grapples with determining the direction for land mobile networks, a small but growing number of mission critical network managers are looking to Mission Critical Push-to-Talk (MCPTT) services for LTE offering Push-to-Talk Over- Cellular (PoC) as an enticing offering for non-public safety needs. Aging analog LMR (Land Mobile Radio) infrastructure needing replacement or significant upgrades, coupled with limited financial resources make PTT services attractive. MCPTT will likely gain more traction as services meeting 3GPP standard are rolled out beginning in 2017.
