LIGHTNING PROTECTING SYSTEMS

Transients are the most potentially damaging power disturbances in a power distribution network. Transients are sudden high peak events that raise the voltage and/or current levels in either a positive or a negative direction.

Transients are caused by :

 

  • Lightning strike.
  • Poor grounding.
  • The switching of inductive/capacitive loads.
  • Utility fault clearing.
  • Electrostatic discharge (ESD).

Lightning is a dangerous weather phenomenon that could cause  billion of dollars worth of damages to Electrical, Electronics and Telecommunication equipment if not protected.

Lightning can have the following effects on a building structure viz: 

  • Heat, fires, structural damage from instant vaporization of trapped moisture (e.g. explosions from concretes)
  • High voltage and high current surges along conductors over long    distances.
  • High voltage and high current surges along ground over short distances.
  • A strike hitting individual could cause serious injuries or even death.
  • Earth current transients, atmospheric transient and bound charge which could cause Arcs.

Our lightning protection solution is capable of arresting any form of thunder and lightning discharges, thereby keeping your structure and the equipments therein in safe-mode.

Our solution is based on the INDELEC PREVECTRON R2-MODEL, which comes in different categories based on the radius of coverage of the Prevectron unit, which is a function of the sensitivity of the equipment under protection and the length and height of the building.
