Lightning & Surge Protection Blog
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.
Millions of people rely on railroads to efficiently travel from place to place. It’s no secret the tracks these trains run on are located in harsh environments near high power lines and other man-made contributors to poor power quality. Since the tracks themselves act as conductors for lightning events, surge protection proves to be a vital contributor to the reliable operation of trains.
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.
