Rt = VRRM / IFSM
Rt is the equivalent resistance of any protective element which ensures that IFSM is not exceeded
Rt ist der Ersatzwiderstand eines jeglichen Schutzelementes, welches ein Überschreiten von IFSM verhindert
4
CL = 5 ms / Rt
If the Rt CL time constant is less than a quarter of the 50Hz mains period, CL can be charged completely in a
single half wave of the mains. Hence, IFSM occurs as a single pulse only!
Falls die Rt CL Zeitkonstante kleiner ist als ¼ der 50Hz-Netzperiode, kann CL innerhalb einer einzigen
Netzhalbwelle komplett geladen werden. IFSM tritt dann nur als Einzelpuls auf!
