<p>A turbogenerator (12) with at least 1 MVA power is arranged in a housing and has a stator winding. At least one high-voltage resistant current measurement apparatus is arranged inside the housing (1) to measure the current that flows in at least one of the leads of the stator winding. The current-conducting lead of the stator winding to be measured follows substantially the shortest path inside the housing (1). The current measurement apparatus contains at least one current converter (3) with a measurement line which leads out of the turbogenerator housing (1). A star point (4) of the current to be measured and several current converters (3), in particular for a differential protecting circuit, may thus be accommodated in the housing (1), dispensing with costly high-voltage resistance leadthroughs through the housing (1).</p> |
