Abstract: A transformer including an active part (100), a transformer tank (214), and one or more tank shunts (105, 106a, 106b, 106c, 107a, 107b, 218, 300). The active part (100) includes a core (102, 202) and windings (104a, 104b, 104c) around the core (102, 202). The transformer tank (214) includes a tank wall (306), and the transformer tank (214) houses the active part (100) of the transformer. The one or more tank shunts (105, 106a, 106b, 106c, 107a, 107b, 218, 300) are configured to capture a leakage of a magnetic flux (B) from the windings (104a, 104b, 104c), in which the one or more tank shunts (105, 106a, 106b, 106c, 107a, 107b, 218, 300) are arranged between the windings (104a, 104b, 104c) and the tank wall (306). Each one of the one or more tank shunts (105, 106a, 106b, 106c, 107a, 107b, 218, 300) also includes a casing (112, 116, 301), in which the casing (112, 116, 301) of said one or more tank shunts (105, 106a, 106b, 106c, 107a, 107b, 218, 300) houses a magnetic fluid (302).
