No transmission during thunderstorms?

[Jens]

hello,
Here one can see that there were severe thunderstorms in southern Sweden on the morning of June 30, 2024.
In the event of a severe thunderstorm:

In this case, would the broadcast not take place to protect the System?

How is the Alexanderson system actually protected from lightning strikes?

Dear Jens,
The secondary windings of the two transformers in the high frequency amplifier system are directly connected to the antenna. The voltage generated across the secondary windings is 2000 V, so here are high requirements for voltage strength of the insulation.
In addition, the secondary windings must withstand lightning strikes coming in from the antenna.

As protection for the secondary windings, they are connected to an over-voltage protection, a so-called Jacob’s ladder.
In the event of an over-voltage, an flash-over occurs on the protection and the arc is then led up into the “horns”, where it goes out.
Lightning strikes have thus not been an obstacle to run the transmitter.
