Abstract
A monitoring system includes at least one partial discharge (PD) sensor. The PD sensor is configured to monitor a component of an aircraft wiring system and to acquire a monitoring signal. A method embodiment for monitoring an aircraft wiring system includes acquiring a number of monitoring signals for a number of components of the aircraft wiring system using a number of partial discharge PD sensors. The method further includes conveying the monitoring signals from at least one of the PD sensors to a data acquisition system.
Claims31
A monitoring system comprising:
- at least one partial discharge (PD) sensor, which is configured to monitor a component of an aircraft wiring system and to acquire a monitoring signal.
An on-board monitoring system comprising:
- a plurality of monitoring units, each monitoring unit being configured to monitor a component of an aircraft wiring system and comprising at least one partial discharge (PD) sensor;
- and
- a data acquisition system, which is configured to receive a plurality of monitoring signals from said monitoring units.
A method for monitoring an aircraft wiring system, said method comprising:
- acquiring a plurality of monitoring signals for a plurality of components of the aircraft wiring system using a plurality of partial discharge (PD) sensors;
- and
- conveying the monitoring signals from at least one of the PD sensors to a data acquisition system.
A method for on-board monitoring of an aircraft wiring system, said method comprising:
- acquiring a plurality of monitoring signals for a respective plurality of components of the aircraft wiring system using a plurality of partial discharge (PD) sensors;
- conveying the monitoring signals from at least one of the PD sensors to a data acquisition system;
- converting each of the monitoring signals to multi-level monitoring signals;
- conveying the multi-level monitoring signals to a data acquisition system;
- storing the multi-level monitoring signals in a memory of the data acquisition system;
- transmitting an alert, if one of the multi-level monitoring signals indicates possible damage to the respective component;
- and
- displaying a wiring health status for the components based on the multi-level monitoring signals.
A monitoring system comprising:
- a test interface, which is configured to connect to a component of an aircraft wiring system, said test interface comprising at least one partial discharge (PD) sensor, which is configured to monitor the component and acquire a monitoring signal;
- and
- a data acquisition system which is configured to receive the monitoring signal.
