Coupling Line to Line

Coupling with 40  resistor and 0.5 µF capacitor
4.2.1.
Example for coupling as per IEC 61000-4-5
Capacitive with 0.5 µF and 40  resistor
Coupling:
Coupling Path: Line L1 (S2) to Line L3 (S1)
4.2.2.

Coupling with 40 Ohm and Gas Discharge Tube (GDT)

Use only bridges with built in GDT (gas discharge tube). Otherwise the generator circuit is
loaded with the line voltage in series with 40 . This can destroy the generator
Example for coupling as per IEC 61000-4-5
Gas discharge tube (GDT) and 40  resistor
Coupling:
Coupling Path: Line L2 (S2) to Line L4 (S1)
Max. applied EUT voltage with GDT coupling is given by the GDT breakdown voltage of 90 V.
Other line voltages may require an GTD with adapted line voltage.
