How can we help?
Lightning Surges are brief but powerful over-voltages and over-currents often accompanied by electromagnetic & radio frequency interference (EMI/RFI) lasting up to a few hundred microseconds, reaching in excess of 100,000 volts. Surge sources vary. Besides external sources such as lightning, power system faults and utility grid switching to internal sources which are generated by load switching also generate destructive surges. A coordinated lightning surge protection plan comprised of a layered defense is the best approach in eliminating the destructive effects of both external and internal surges.
IEEE std 1100 states: In addition to surge protective devices installed in the service entrance equipment, it is recommended that additional surge protection devices of listed Category “B” or Category “A”, as specified by IEEE std. C62.41-2002, be applied to downstream electrical switchboards and panel-boards on secondary or separately derived systems if they support communication, information technology equipment, signaling, television, or other forms of electronic load equipment.
IEC std 62305 states for Protection to reduce the failure of internal systems: The protection against lightning electromagnetic pulses (LEMP) to reduce the risk of failure of internal systems shall limit:
- over-voltages due to lightning flashes to the structure resulting from resistive and inductive coupling
- over-voltages due to lightning flashes near the structure resulting from inductive coupling
- over-voltages transmitted by lines connected to the structure due to flashes to or near the lines
- magnetic field directly coupling with internal systems
Effective protection against over-voltages, which can cause failures within internal systems, may be achieved by means of a “coordinated surge protection.” Coordinated sure protection can limit over-voltages below the rated impulse voltage of the system it’s meant to protect.
