Introduction
HUBER+SUHNER 11
Induction circuit
Electromagnetic interference of nearby lightning hits or even the LPS itself
RF/Data Bonding bar
Power supply
Earth termination system
Magnetic field coupling
The lightning current of near-hits or even a downconducted
one of the existing LPS (Lightning Protection
System) induces surge currents and voltages in any
effective electrical loop. This is determined by the average
steepness of the lightning current as well and follows
the formula:
U = –M * diL/dt (M for mutual inductance)
Electric field coupling
The effects of the high and changing electrical field
strength right before the hit occurs is normally negligible
when considering a minimum of protection measures.
