Zusammenfassung:The present disclosure relates to a transformer system (10) comprising a power transformer (1) comprising a metal tank (2) filled with an electrically insulating liquid (3), and a wireless sensor arrangement (11) submerged in the insulating liquid within the tank. The sensor arrangement comprises a radio transmitter (12) for wirelessly transmitting sensor readings to the outside of the transformer through an opening (4a and/or 4b) in the tank, said opening being provided with a liquid-tight seal comprising a solid insulator for preventing leakage from the tank of the insulating liquid.
