A drilling assembly for use in drilling of a wellbore is disclosed that in one non-limiting embodiment includes a device that detects a flow-off state, a power generator that generates electrical energy in response to a fluid flowing through the drilling assembly during the flow-off state, and a circuit that utilizes such power to perform one or more selected operations in response to the detection of the flow-off state, including, but not limited to, storing data in a memory; shutting certain devices in the drilling assembly and parking a device in a desired position.

Downhole tools with power utilization apparatus during flow-off state

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.
