Abstract (en)
[origin: EP1696444A2] The transformer has a passage opening which continues in a direction of a center axis and is designed for receiving a primary conductor that is monitored with respect to a residual current. Magnetic cores (2, 3) surrounding the passage opening are wound with primary and secondary windings (6, 7), respectively. Magnetic shields (10, 11) are arranged between a compartmentalization (20) and the magnetic cores.
