Lightning rod is a common name used to refer to a system installed on the top of a building or on a high pole, consisting of one or more metal rods with pointed ends connected to ground conductors for protection. for structures, buildings and objects below from being struck by lightning.
The surge protection selection must be done following the local electrical code requirements (e.g. : minimum rating for In) and specific conditions (e.g. : high lightning density).
Alongside lightning rods that protect structures, transient surge protection plays a crucial role in protecting internal electrical and electronic devices.
Learn about the lightning protection system (LPS): definition, purpose, types, and detailed installation guide to protect buildings and equipment from lightning damage.
Surge surge protection devices (SPDs), also known as surge suppressors, are specific products in the electrical industry, the specifications of lightning protection devices on documents or products displayed Displays symbols and parameters to describe their own properties. Based on these parameters we can understand and compare the technical features of the devices, in order to use them most effectively.
Lightning protection involves using technical measures and systems to protect people, property, and infrastructure from the harmful effects of lightning. This system helps minimize the risk of damage caused by direct lightning strikes or induced surges.
Different electrical networks have different specifications and connections, so manufacturers have designed products for their respective protection installations. If selected incorrectly and installed improperly, not only will it lose its effectiveness, but it can also cause damage, fire, loss of electrical safety and affect the entire system.
Brazilian researchers captured on camera the moment when lightning rods on buildings released an upward discharge to attract incoming lightning.
What is the resistivity of the earth? The resistance of a cube earth is 1m3, to the current flowing from one side of the earth block to the opposite face. The unit of resistivity of soil is Ωm (ohm meter). It is possible to measure resistivity of soil according to the Wenner or Schlumberger method.
