Abstract
A method is presented for detecting a lowering of a current collector of a vehicle, in particular a rail vehicle, from a contact line, the method comprising: determining values of the electric current intensity of an electric current that is transmitted or flows between the contact line and the current collector in a measuring period; determining values of a current component of the electric current with the aid of the values of the electric current intensity; detecting the lowering with the aid of the values of the current component and a predefined criterion. Furthermore, a corresponding apparatus and a vehicle comprising the apparatus are disclosed.

A method for detecting a lowering of a current collector of a vehicle, in particular a rail vehicle, from a contact line, the method comprising:
- determining values of an electric current intensity of an electric current that is transmitted or flows between the contact line and the current collector in a measuring period;
- determining values of a current component of the electric current by means of the values of the electric current intensity;
- and
- detecting the lowering taking into account the values of the current component;
- characterised in that the current component is a direct current component, or the current component is an alternating current component having a frequency value below a predefined frequency value.
An apparatus for detecting a lowering of a current collector of a vehicle, in particular a rail vehicle, from a contact line, the apparatus comprising:
- a determination device designed to determine values of an electric current intensity of an electric current that is transmitted or flows between the contact line and the current collector in a measurement period,
- wherein the determination device is additionally designed to determine values of a current component by means of the values of the electric current intensity, or the apparatus comprises a further determination device designed to determine values of a current component by means of the values of the electric current intensity;
- and
- a detection device designed to detect the lowering taking into account the values of the current component,
- characterised in that the current component is a direct current component, or the current component is an alternating current component having a frequency value below a predefined frequency value.
