Abstract
A method and device for operating a power distribution node can include a controllable switching element configured to switch between supplying a power supply to an electrical load and not supplying the power supply to the electrical load, an electrical sensor connected in series to the controllable switching element and configured to generate a monitoring signal representative of an actual switching pattern of the controllable switching element, and a monitoring controller module receiving the monitoring signal.
Claims20
A power distribution node, comprising:
- a controllable switching element configured to switch between supplying a power supply to an electrical load and not supplying the power supply to the electrical load and to encode a validation signal in a desired switching pattern of the switching element;
- an electrical sensor connected in series to the controllable switching element and configured to generate a monitoring signal representative of an actual switching pattern of the controllable switching element;
- and
- a monitoring controller module receiving the monitoring signal and configured to determine the operating status of the power distribution node by validating the monitoring signal against a validation signal.
A method of validating the operation of a power distribution node, the method comprising:
- encoding a validation signal in a desired switching pattern, by a switch controller module;
- controllably requesting a switching element to perform a switching pattern in accordance with the desired switching pattern, by the switch controller module;
- sensing, by an electrical sensor, an actual switching pattern of the switching element;
- determining, in a monitoring controller module, the operating status of the power distribution node by validating the actual switching pattern against the validation signal;
- and
- providing indication of the operating status of the power distribution node.
