How Many Meters Can A Movie Projector Can Be

lightning branch. Why?

Lightning is in the air a distance of ionized gas. This gas has excellent electrical properties, ie, it passes very well. The ambient air, however, derives almost no electricity. If now builds the fire, the distance on the borders of neutral gas, namely air, unstable, and there is the familiar and distinctive branches. The flash is divided into several "fingers". Depending on the strength of the electric field leads to many or a few fingers. But the branch that ultimately connects the cloud to ground, is used to balance the charge after the flash back completely degrades.

Why leave your lightning protection system checked regularly

A properly and professionally installed lightning protection system at your home can damage by direct Prevent lightning strikes as far as possible. But in order to function properly throughout the lifetime guarantee and ensure lightning protection systems must be periodically maintained and tested!
Compare the facts with your car. If you have a car, you also do not have to TÜV. However, you have a car, you are legally obligated to have it regularly check on his safety out. When lightning although there are no statutory provisions, but if you have one, you must let it wait, or are at risk in case of damage (third party damage) severe consequences. If you
structural changes have have carried out, such as through cultivation, a roof restoration or installation of a photovoltaic system, they must already be integrated into an existing lightning protection. On this occasion, the system can easily sift and if necessary, repaired it.
The materials of an external lightning protection are subject to relatively strong external influences. Play electrolytic processes and the resulting corrosion of the grounding components a major role.
The grounding of course be subjected to a measurement test, the resistance is measured. Fully
Rusty Earth electrodes can not perform their function more at risk and The purpose of the entire lightning protection and must be replaced immediately by new ones.
As with the lightning protection lightning protection method determines the class intervals to be where one test has. To advise is to be carried out every 3 years, a "maintenance service". A lightning protection specialist sees the facility to accurately and performs measurements on the compounds and the earth electrodes. Of course, the work documented and it creates a new test report.
