For well coordinated operation between the type 1 lightning arrester and the type 2 surge arrester, in complex lightning and overvoltage
protection systems sufficient value of cable/wire impedance must be provided to enable voltage drop.
This condition is satisfied if the length of cable/wire is at least 10 – 15 meters. If this condition cannot be satisfied, an inductive reactance
(decoupling coil) must be used.
