3-Main applications
  • Low Voltage SPD
Very different devices, from both a technological and usage viewpoint, are designated by this term. Low voltage SPDs are modular to be easily installed inside LV switchboards.
There are also SPDs adaptable to power sockets, but these devices have a low discharge capacity.

4-Principle

SPD is designed to limit transient overvoltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this overvoltage to a value that is not hazardous for the electrical installation and electric switchgear and controlgear.

===================================

5-SPD Eliminates Overvoltages
  • in common mode, between phase and neutral or earth;
  • in differential mode, between phase and neutral.

In the event of an overvoltage exceeding the operating threshold, the SPD

  • conducts the energy to earth, in common mode;
  • distributes the energy to the other live conductors, in differential mod
  • ===================================
6-Common Characteristics
  • Uc: Maximum continuous operating voltage
This is the A.C. or D.C. voltage above which the SPD becomes active. This value is chosen according to the rated voltage and the system earthing arrangement.
  • Up: Voltage protection level (at In)
This is the maximum voltage across the terminals of the SPD when it is active. This voltage is reached when the current flowing in the SPD is equal to In. The voltage protection level chosen must be below the overvoltage withstand capability of the loads. In the event of lightning strokes, the voltage across the terminals of the SPD generally remains less than Up.
  • In: Nominal discharge current
This is the peak value of a current of 8/20 µs waveform that the SPD is capable of discharging minimum 19 times
Why is In important?
In corresponds to a nominal discharge current that a SPD can withstand at least 19 times: a higher value of In means a longer life for the SPD, so it is strongly recommended to chose higher values than the minimum imposed value of 5 kA.
  • Imax: Maximum discharge curren
This is the peak value of a current of 8/20 µs waveform that the SPD is capable of discharging once.

Why is Imax important?

If you compare 2 SPDs with the same In, but with different Imax: the SPD with higher Imax value has a higher "safety margin" and can withstand higher surge current without being damaged
