Apparatus for measurement of a DC voltage of a DC voltage source. An electrode forms a capacitive connection with the DC voltage source. A non-linear capacitor has a first node connected to the electrode. An initial voltage source is arranged to generate an initial voltage. A switch is arranged to selectively apply the initial voltage to a second node of the non-linear capacitor. A voltage sensor is arranged to measure the voltage of the second node of the non-linear capacitor and a processor is programmed to deduce the DC voltage of the DC voltage source by analysing the rate of decay of the measured voltage. |
