If this is a lightning discharge between two clouds light mobile or between light mobile the earth and if AC is called lightening. When the clouds are moving in the positive and negative electrical charges that are looking for a place to dump their load on the track or around tall buildings or tall trees are more taper accumulation of electric charge and unloading of the do not reach the ground.
Because the clouds pregnant at the same place so they do not get unloaded until all have completely lost their charge up the earth will not reach. Therefore light mobile be seen as a branch.
However, when the clouds are high. Impact light mobile and ultraviolet radiation (climate change) will be charged and the air resistance light mobile of the insulation breaks down and the results are conductive and may drain discharge takes place between two clouds or cloud and the earth.
Air resistance varies light mobile in different parts, for example in some places and in some places more is less humidity light mobile or other factors which may cause the publication of this resistance is an electrical current to and the Congress of direct.
Perhaps the simplest of these events is the lack of awareness of safeguarding procedures. In addition to the false impression that they all have a kind of lightning rod on the outside [of the physical structure avoids the occurrence of sparks Vtkhrb] can all electrical and electronic equipment inside the building to protect Ranyz.
Lightning is one of the most Azasrar phenomena of creation, which is very destructive beauty while Vdrtvl on human lives, the loss of financial loss is much John. Electrostatic discharge occurs between the cloud-land of the thunderbolt.
The type of cumulonimbus clouds (sometimes up to 18km altitude of several kilometers wide) stages, positively charged water particles have negative charges as positive light mobile Vbarhay Drlayh underneath the upper cloud are focused Kzmy.
In this case, the ground speed of the approaching channels over 300km / s is. Present time to increase the intensity light mobile of the electric field at ground level, a climbing electric current (upward leader) from the ground to the cloud, it's going. After two arrows hit each other, the main flow channel closed Vzrbh lightning (return stroke) occurs, and thus neutralizes the charge cloud to Earth, the flow in the channel is established very shortly. Lightning occurs in a variety of the most common (90%) of negative lightning Ascending Descending Vkhtrnaktryn them is positive.
Human Lightning damage primarily occurred prior disaster experience, they are less likely to seek the cause of the damage caused Vmkrr initial impact (direct light mobile impact) and secondary (electromagnetic light mobile fields) Lightning today is so much serious attention Vrahkarhay demands.
The first of these events may not be aware of the security procedures, which have a lightning Gyrdr exterior (which just happens to be the spark that destroyed the front of the physical building) electrical and electronic light mobile equipment inside the building as a whole to protect the If that is not the case.
Housekeeping, Kampyyvtr, fax, radio, light mobile TV, telephone, global information networks, electronic circuits made of Andkh expensive Vtmyratshan paying job is not easy and sometimes derail them also coincided with the loss is irreversible.
Added voltages caused electrostatic discharge (Electrostatic Discharge) Added voltages light mobile caused by circuit switching (Switching Electromagnetic Pulse) Added direct hit by lightning induced voltage light mobile electromagnetic Vmydanhay
When building hit by lightning discharges light mobile to ground Zndjryany Vdyta Shvdptansyl ground in electrical systems, gives rise to several hundred kV. Caused by lightning conductors to be part of the input - output to be Dygrmntql buildings.
Lightning channel near the point of discharge, a strong electric field is created. Cables light mobile Vhadyha such as capacitor dielectric insulation Vhvanyz them. Thus, despite the lack of a lightning strike to the building light mobile of a high-voltage cables are placed.
All equipment (eg spark) guidance for attracting lightning ground system installed on the roof so they can be identified according to standard IEC -61024. light mobile 2 - Protection of electrical equipment installed in the building of application light mobile systems in the world, causing damage to the appliance surge statistics induced voltages in Asrsaqh and add it. Should be noted that only part of the added voltages caused by lightning They are mainly caused by the operation of the switching power supply section Vhvads., for this part of the conservation, reduction of electromagnetic fields caused by lightning is considered. After the lightning hit the ground light mobile or building light mobile electronic devices inside the buildings that make up the electromagnetic field within a radius of 15km from Brkhvrdvdr are at risk will be. (Figure 4) effectively protect equipment against induced light mobile voltages resulting it is possible that all internal protection systems are installed with both exterior protection. internal protection devices that aid could be provided Azsaqh consists of over voltages induced by lightning currents thwarted Rabrrvy equipment indoors. region from theory scheme (Zone Concept) is used for interior protection. Also, for detailed information Trbh IEC-61643 standard has been developed in this field are presented.
