Copper ground bars (also known as busbars) are a building block of electrical installations because they provide a common grounding point for multiple electrical circuits. The purpose of ground bars: Safety: They help prevent electrical shock by providing [...]
Many solar operators believe damage or poorly performing PV panels are protected by manufacture warranties. However, we surveyed several major manufacturers and found that every single one exempted damage resulting from lightning. [...]
Mega News for Mega Structures How does it work? The TerraStreamer® ESE lightning terminal is a proactive, externally mounted structural lightning protection device. It is designed to activate itself directly before lightning strikes by emitting electromagnetic impulses [...]
Electrical transients are momentary bursts of energy induced upon power, data, or communication lines. They are characterized by extremely high voltages that drive tremendous amounts of current into an electrical circuit for a few millionths, up to a few thousandths, [...]
Beginning in 2018, Alltec surveyed 29 AWOS sites in the state of South Carolina for goal-oriented grounding systems and lightning protection. Alltec was awarded the honor of being the sole source provider of enhanced grounding systems to the SC [...]
Solar farms are wide-open unobstructed areas of conductive material. It’s no surprise that they are highly susceptible to lightning strikes. Direct strikes may be relatively rare, depending upon a facility’s size and location, so most damage is usually sustained [...]
ALLTEC has developed the best lightning protection system for security camera pods and radio/signaling communications equipment through their cooperation with a US rail transportation company and a wireless provider. ALLTEC was invited to investigate one rail site after [...]
ALLTEC was contracted to perform a lighting protection study of several AN/FPS-117 and AN/FPS-124 radar sites part of the American Canadian North Warning System. Because these radar systems are predominately located in northern latitudes, they have unique environmental conditions [...]
What is soil resistivity? Simply put, soil resistivity is a measurement of how much the soil being sampled resists electric current. Typically, the resistivity varies with depth in soil, moisture, temperature and chemical content. Why is soil [...]
Lightning rods are also known as an air terminal, lightning conductor, finial, and strike termination device provides a conductive path to ground. Charge dissipation terminal -- or charge redistribution terminal -- uses point discharge to reduce static charge [...]
