Electromotive force (EMF) monitoring for an electrical submersible pump (ESP) with permanent magnet motor (PMM)

An electromotive force (EMF) monitoring device for an electrical submersible pump (ESP) having a permanent magnet motor (PMM), comprising:

• one or more voltage and current sensing devices configured to monitor one or more voltages and one or more currents in a plurality of conductors and a cable armor grounding strap of a cable coupled to the ESP having the PMM;
• one or more processors;
• and
• a computer-readable storage medium having instructions stored thereon that are executable by the one or more processors to cause the EMF monitoring device to:
• determine whether the one or more voltages and the one or more currents in the cable exceed one or more thresholds;
• and
• generate a notification to indicate an EMF condition in the cable of the ESP if at least one of the one or more voltages and the one or more currents in the cable exceeds at least one of the one or more thresholds.

A non-transitory computer-readable storage medium having instructions stored thereon that are executable by one or more processors of an electromotive force (EMF) monitoring device for an electrical submersible pump (ESP) having a permanent magnet motor (PMM), the instructions comprising:

• instructions for monitoring one or more voltages and one or more currents in a plurality of conductors and a cable armor grounding strap of a cable coupled to the ESP having the PMM;
• instructions for determining whether the one or more voltages and the one or more currents in the cable exceed one or more thresholds;
• and
• instructions for generating a notification to indicate an EMF condition in the cable of the ESP if at least one of the one or more voltages and the one or more currents in the cable exceeds at least one of the one or more thresholds.
