The invention specifies a method for insulation monitoring for an electrically operable vehicle (1), wherein the vehicle (1) has a first plurality of insulation monitors (32a-32i) and a second plurality of insulation levels (30a-30i), wherein each insulation level (30a-30i) comprises at least one power-electronics component and/or a current-carrying component and/or a ground component, wherein for a first time interval (ΔT1) a central control unit (34) of the vehicle (1) outputs an inhibition signal (I1) to a first subgroup (G1) of the first plurality which comprises at least one first insulation monitor (32a), wherein as a result of the inhibition signal (I1) during the first time interval (ΔT1) insulation measurements (Ma) by the insulation monitor or monitors (32a, 32c-32i) of the first subgroup (G1) are not performed at all, and wherein during the first time interval (ΔT1) an insulation measurement (Mb) is at least temporarily performed at at least one insulation level (30b) of the second plurality by at least one second insulation monitor (32b) which is not part of the first subgroup (G1).
