"textContent": "A method for determining whether an electric insulation of a conductor is sufficient, comprising: - switching on or off a resistive load between the conductor and ground, - measuring a first voltage value u of a resulting voltage U between the conductor and ground at a first point in time t after switching on or off the load, - determining if the first voltage value u fulfils a first condition, and/or determining an initial rate of change of the resulting voltage U between the conductor and ground based on the first voltage value u, and determining if the initial rate of change fulfils a second condition, - determining that the electric insulation is sufficient when at least one of the first and second conditions is fulfilled. [0002] When the electric insulation is not determined to be sufficient, the method further comprises: - predicting a voltage response U over time between the conductor and ground, - initiating a continuous measurement of the resulting voltage U and comparing U to U, - determining a point in time when a relation between U and U fulfils a predetermined third condition, and therefrom predicting a steady-state voltage Uss, - using the steady-state voltage u, estimating whether the electric insulation is sufficient.",
