摘要： Aspects of the disclosure can relate to detecting and accounting for fault conditions affecting electronic devices. In implementations, electronic devices can be coupled to one another in series with a common power line linking the electronic devices together. For example, the electronic devices can include down hole tools/equipment of a drill string. In embodiments, a system can include circuitry configured to couple a first electronic device with a second electronic device. The circuitry can detect or receive information regarding a fault condition and can set a switch to an open position, where the first electronic device and the second electronic device are electrically disconnected from one another, when a fault condition affects or is caused by the second electronic device.
