Abstract: Techniques for monitoring the health of a three-phase induction motor are provided. An expected threshold value is calculated as a function of an expected ratio of current unbalance to voltage unbalance for the three-phase motor. Embodiments determine whether a measured current unbalance exceeds the expected threshold value. Responsive to the measured current unbalance exceeding the expected threshold value, a remedial action may be taken, such as generating diagnostic information or activating one or more protection operations for the three-phase induction motor.

Abstract: Gravity driven reverse circulator tools are provided and methods of using same. One tool has nested pipes that when fully nested close a hole in one of the pipes, but when the drillstring is lifted, the pipes partially separate under the force of gravity to expose the hole. The other embodiment is similar, but the hole is hook shaped (hook on top as in a walking cane) and a protrusion from the other pipe fits in the hole. Thus, both lifting and rotation are needed open the tool.

Abstract: Disclosed are systems and methods for pressure testing coiled tubing (CT) in a well. A CT pressure testing device may include a CT connector for attaching to a CT segment and a pressure test housing defining a pressure chamber. A rod may extend through a top opening of the pressure test housing and through the CT connector to the severed end of the CT segment. A sealing plug coupled to a bottom end of the rod may create an interface between the CT connector and the CT segment. A force activator may apply a force to a top end of the rod, causing the rod to push the sealing plug into the CT segment and tighten the interface. A pump may pressurize the pressure chamber to perform a pressure test on the sealing plug. Accordingly, the CT pressure testing device may establish a well control barrier for the well.

Abstract: A method, apparatus and computer program product resolve the problem of unbalanced loads in an EVSE cluster of multiple EVSE charging stations. A signal is provided to the EVSEs identifying which phase of the three-phase power source has the highest current. When one of the EVSEs in the cluster determines whether it is connected to an EV's on board charging device, determines whether it is already charging the connected EV, and determines whether the EVSE is using the phase that has the highest current, then the EVSE may transmit a cluster load balancing control signal as a control pilot signal to the EV's onboard charging device to adjust the charging rate of the current that the EV is consuming from the EVSE.

Abstract: Methods of plugging a hydrocarbon well by using degradable plugs are provided. When the plug is no longer needed, a degradation fluid or fluids are pumped downhole under high pressure, typically via jet, such that the degradation fluid provides an erosive force to the degradable plug, thus both speeding its degradation and preventing or minimizing the leaving of solid plug material remnants in the well.

Abstract: A progressive protection method automatically adapts a protection trip delay or fault timeout for a motor that is a member of a group of motors performing mutually similar or related tasks, based on the occurrence of a fault in another motor within the group, without requiring manual intervention. If the user requires stringent protection of the motors in a particular application, then the trip delay time for all of the motors in the group, may be shortened in response to recently-detected similar trips of other motors within the group. Alternatively, if the user prefers continuity of service for a particular application, then the trip delay time for all of the motors in the group, may be increased in response to recently-detected similar trips of other motors within the group, based on past experience with the occurrence of fault self-clearing for the motors in the group.
