<p>A device for measuring AC and DC current in an electrical network, to determine residual current and earth faults for example. A current transformer (78) is provided and a resistive shunt (70) is connected in series with a line in or line out power conductor. The resistive shunt is located on the current transformer or current transformer case, optionally via a mounting insulator (71) inserted into the aperture of the current transformer.</p> |
