SPD for lightning protection equipotential bonding ac-
cording IEC 62305 for direct nearby lightning
strikes.
For insulation coordination, the protection level the
SPDs must less than equal the rated impulse
voltage the electrical system according IEC
60364-5-53.Choosing the right surge protection devices
The classification surge protection devices into
types means they can matched different require-
ments with regard location, protection level and cur-
rent-carrying capacity.5 kV
