Abstract
The invention relates to a surge detector comprising a transformer comprising a primary winding arranged to receive a fraction of a surge current and a secondary winding magnetically coupled to the primary winding and arranged to output a signal representing the fraction of the surge current. The surge detector further comprises a shunt connection in parallel with the primary winding, wherein the impedance of the shunt connection is lower than the impedance of the primary winding.
