Abstract: A fault managed power system (FMPS) measures leakage current in an electronic circuit. The FMPS comprises a source controller, leakage current sensor, pulsing controller, and load end circuit. The source controller generates a pulsing input defining a current-on time interval and current-off time interval. During the current-off time interval, a source driver of the source controller opens a source switch to disconnect power from a power source. The leakage current sensor utilizes a leakage current sensor driver to open a leakage current sensor switch. The pulsing controller utilizes a pulsing driver to close a pulsing switch to provide a return path for leakage current during the current-off time interval. A holdup capacitor at the load end circuit reverse biases a blocking diode to isolate a load from the electronic circuit, such that leakage current flows in the leakage current sensor to enable an accurate measurement of the leakage current.

Abstract: Described herein are systems and techniques for monitoring substances that are injected into an Earth formation whether that be CO2 from a carbon capture and storage (CCS) process, or water or steam injected for an enhanced oil recovery (EOR) process. Components located on an outside of a wellbore casing may be electrically isolated from components located on the inside of the wellbore casing. Data and/or power may be transferred through the wellbore casing wirelessly in order to increase the reliability of a data collection system because the need for wires to be placed on the outside surface of a wellbore casing is eliminated. The components located on the outside of the casing may receive electromagnetic (EM) or transmit EM fields as part of a system that collects data about substances that are injected into Earth formations during a CCS or EOR process.
