It is recommended that Lightning Protection Systems be inspected at least annually.
Electing longer or shorter inspection intervals should be determined by factors at the discretion of the owner.

Conductor Cables - Heavy cables (right) that carry lightning current from the rods to the ground. Cables are run along the tops and around the edges of roofs, then down one or more corners of a building to the ground rod(s). Ground Rods - Long, thick, heavy rods buried deep into the earth around a protected structure.

The function of an external lightning protection system is to intercept, conduct and disperse a lightning strike safely to earth. Step and touch voltages generated from a lightning strike can cause injury, or even loss of life, to humans (and animals) in the close vicinity.

*Create a low impedance path to the ground for any of the possible impacts.
*This protection system will keep your structure away from any impacts.
*Significantly reduces heat, mitigating the danger of fire.
*Shielding action more effective for shielded cables.

WHAT IS LIGHTNING PROTECTION?
A lightning protection system is designed to keep your structure or site safe from any damage that lightning may cause. This is done by intercepting the lightning as it passes safely over you to the ground. This lightning protection system involves a network composed of different air terminals, grounding electrodes and connecting conductors.

-Grounding wires keep us safe around electrical currents, allowing electricity to have an everyday presence.
-Grounding reduces the risk of severe electrical shock from uninsulated metal components inside of electrical devices, appliances and power tools.
-Predictable fault current return.
-Equipment bonding.
-Minimize ground potential rise (GPR), keep areas safe during faulted conditions.
-Protection for: 1.Personnel 2.Equipment

*Overvoltage Protection: minimizing damage and sending that extra charge safely into the ground.
*Safety: provides a certain level of safety for humans and protects property.
*Voltage Stabilization: helps to monitor voltage sources to one another, preventing a hazard that could easily occur.

-Good (low resistance) grounding systems increases life safety.
-Reduces standalone and networked systems noise.
-Protects from lightning and unwanted voltages.
-Power surges and impulses can be shunted by surge protection devices.
-Circuit breakers can function properly.
-Lightning protection systems can operate properly.

GROUNDING FUCTIONS.
*Minimize the voltage between exposed metal and the ground.
*Provide a sink for lightning, power line crosses, and similar hazards.
*Minimize the voltage between the power wires and the earth.
The grounding studies will detect any installation or calibration errors in your grounding system. These include things such as problems in tripping tolerance (too sensitive or too insensitive), polarity issues, and neutral connections to ground
