FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and downhole equipment. Device contains a sealed housing with current and voltage sensors located in it, installed on each phase of the supply cable, which record the number of discharges, duration, amplitude, date and time of occurrence of overloads. In this case, the housing is configured to be connected to a submersible motor, the device for recording, identifying overloads and estimating the residual life of insulation of submersible motors further comprises an analog-to-digital converter, a microcontroller, modem with the function of broadband transmission of measurements through the supply cable to the submersible motor control station for data storage and processing.
EFFECT: invention can be used for registration, identification of overloads and evaluation of the residual insulation life of submersible motors (SMM) in the electric centrifugal pump (ECP) unit.
