    • A chamber (3) in a rigid casing contains a winding (4) and is filled up with a gel (10) with a storage modulus and a loss modulus each between 1OPa and 10'000Pa, preferably between 1OOPa and 1'OOOPa. In a separate compartment (11) a separator (14) is arranged which will disrupt a conductor band (15) connecting the winding (4) with a first electrical contact (7) actuated by a membrane (12) if the pressure in the chamber (3) reaches a threshold. Due to the use of the gel (10) as a filler a crack in the casing will not lead to spill while any increase in pressure caused by damage to the winding (4) and out-gassing of the same is, due to the plasticity of the gel (10), reliably transmitted to the membrane (12), causing the same to actuate the separator (14) to disconnect the winding (4) if the pressure reaches the threshold. A cushion (9) inside the chamber (3) compensates thermal expansion of the winding (4) and the gel (10).
