摘要： A power control device includes a communication device configured to be disposed in a borehole and configured to couple electrical power from a power source to a downhole component from a conductor disposed along a borehole string, a circuit breaker system including a first circuit breaker disposed at a connection between the conductor and the downhole component and configured to be closed to connect the downhole component to the conductor, and a controller configured to monitor at least one of a current level and a voltage level at the connection and at the conductor. The controller is configured to control the circuit breaker system and autonomously perform opening the first circuit breaker in response to detecting a deviation in the at least one of the current levels and voltage levels at the connection, to isolate the downhole component from the conductor and the power source.

摘要： A system for determining an order of electronic components in a downhole string includes a plurality of electronic components connected in series by a conductor and forming a series of electronic components, the plurality of electronic components including a master electronic component. For each electronic component in the series of electronic components, the controller is configured to detect a power direction, where the power direction is an uphole power direction when power from the power supply is received at an uphole side of the electronic component, and is a downhole power direction when power is received at a downhole side of the electronic component. The controller is configured to send a message through the conductor including an indicator indicating the power direction, and the master electronic component is configured to receive the message and determine an order of electronic components in the series of electronic components based on the indicator.
