Zusammenfassung:	A method of installing a submersible electrical pump assembly in a well monitors the integrity of the pump assembly and electrical cable while the pump assembly is being run. The pump assembly has at least one sensor that measures a parameter in the environment of the pump assembly. A battery-powered test unit is mounted to the reel of cable, and a lead of the unit is connected to the power cable. While lowering the completion equipment, test voltage is supplied from the unit via the power cable through the motor to the sensor. The unit transmits an indication to a remote monitor that the sensor is operational.
