Product Description


EPS 1Pole + N 40KA Voltage Surge Protector

A - Overvoltage of atomospheric origin propagation modes

1) Direct Attack

  • This occurs at the point of impact and may result in powerful currents flowing through fairly conductive elemants .

2) Indirect Attack

  • These occur most frequently , where a single direct attack at a point can generate overvoltages at a distance which are then propagated via the electrical supply right inside the bulding and can damage the installation and electrical enquipment .

a) Overvoltages on overhead power lines

  • when lightning strikes a high or low-voltage overhead power line and creates an overvoltage of several thousand volts and a current of a several thousand amps .

b) Overvoltages due to elec tromagnetic coupling

  • when lightning strikes in the vicinity of an electrical supply creates an overvoltage caused by electromagnetic radiation which is propagated to the buliding electrical installation directly or via the electrical supply .

c) Overvoltage from the earth system 

  • when a lightning strikes the ground and generates an increase in the earth system potential which is fedback to the installation .

B - Overvoltage of non-atmospheric origin

  • These are overvoltage resulting from operation on equipment such as : motor ( lift ) , sodium lamps , etc .


C - Effects of overvoltages

​There are two types of overvoltage 

  • overvoltage between the supply and the metal structure or earth system : these result in the creation of an electrical arc between the supply and earth , this results destruction of the cunsumer unit .
  • overvoltages between phase and neutral these damage the actual electrical appliance .
