Abstract
An example system is configured to detect a fault in a bundle of wires. The bundle of wires include a first wire and a second wire. The system includes a first driver that is electrically connectable to, and electrically disconnectable from, the first wire; a second driver that is electrically connectable to, and electrically disconnectable from, the second wire; and a control system to control the first driver to electrically connect to the first wire and to output a signal to the first wire, to control the second driver to electrically connect to the second wire and to drive a static voltage to the second wire to enable the second wire to act as a signal return for the first wire, and to detect a fault in the first wire based on a reflection of the signal on the first wire.
Claims27
A system for detecting a fault in a bundle of wires, the bundle of wires comprising a first wire and a second wire, the system comprising:
- a first driver that is electrically connectable to, and electrically disconnectable from, the first wire;
- a second driver that is electrically connectable to, and electrically disconnectable from, the second wire;
- and
- control system to control the first driver to electrically connect to the first wire and to output a signal to the first wire, to control the second driver to electrically connect to the second wire and to drive a static voltage to the second wire to enable the second wire to act as a signal return for the first wire, and to detect a fault in the first wire based on a reflection of the signal on the first wire.
A method of testing a first wire, comprising:
- controlling a first driver to output a signal on the first wire;
- controlling a second driver to drive a static voltage to the second wire to cause the second wire to act as a signal return for the first wire;
- obtaining data based on a reflection of the signal on the first wire;
- and
- testing the first wire based on the data.
