Protection of PS systems from direct and indirect effects of lightning

Protection of PS systems from direct and indirect effects of lightning

Recently, close attention has been paid to improving the reliability of fire alarm and fire extinguishing systems. This is due to the proliferation of large public buildings (giant shopping malls, indoor stadiums, etc.), high-rise construction, as well as increasingly sophisticated equipment used in crowded places (for example, in amusement parks). It should be noted that not only failure of the alarm system, but also its systematic false alarm is dangerous.

What lightning can break through?

What lightning can break through?

It would seem that a tremendous amount of energy is concentrated in the lightning bolt, capable of causing great mechanical damage to any object in its path. In fact, the real danger is not that great. Figure 1 shows a picture of a steel tip of a flagstaff from the Ostankino TV-tower with the traces of multiple lightning strikes. The size of the image is maximally close to the real one.

Protection of fuel storages with floating roof from static electricity

Protection of fuel storages with floating roof from static electricity

When storing fuels and lubricants, a major problem is expansion and contraction of the fluid depending on the temperature of the environment. In case when a storage represents itself a rigid metal tank, then some space filled with air is left in it so that, due to compression-expansion, there is no deformation of the container. Fuel and lubricants evaporate into this space. When the storage is ...
