Abstract
An aircraft electrical system includes a controller system having a self-testing system configured to test an operability of a transient voltage suppression device. A single line communication bus is connected to a communications output of the controller. A first lightning protection device including the transient voltage suppression device is configured to protect the controller from transient voltages. An enable/disable circuit comprising a normally closed switch connects a low side of the lightning protection device to a neutral.
