An electric motor of an electric submersible pump is electrically isolated from a power conduit for diagnostic testing of the power conduit and wet connection components in place within a wellbore. The electric motor is electrically connected to the power conduit through a wet connection assembly having motor leads in electrical connection with a transfer contact and a receptacle assembly disposed on a tubing string having a supply contact electrically connected to the power conduit. Electric power flows through the power conduit, through the supply contact, through the transfer contact, and through the motor leads to the motor. The supply contact and the transfer contact are separated by a sliding sleeve that hydraulically inserts between the contacts, insulating the transfer contact and grounding the supply contact for testing. The contacts may also be separated by a relative rotation of the assemblies that grounds the supply contact for testing.

Isolating wet connect components for deployed electrical submersible pumps

Systems and methods for employing gauge packages for use with a wet-connect ESPs. In one embodiment, a modular gauge package includes a body, a gauge electronics assembly housed within the body, and a pair of electrical connectors at the upper and lower ends of the body, where power is passed through the body from one connector to the other. The electrical connector at the top of the body engages a complementary electrical connector on the bottom of a pump motor. The electrical connector at the bottom of the body engages a complementary electrical connector at the end of a production conduit. The connector at the bottom of the body may be identically configured with the connector at the bottom of the pump motor, and the connector at the top of the body may be identically configured with the connector at the end of the production conduit.
