FIELD: physics.
SUBSTANCE: invention relates to methods and apparatus for checking the technical state of downhole electric centrifugal pump units when conducting maintenance work. The system has in its downhole part measurement modules connected by a data bus which is connected to a communication channel, whose output is connected through a first interface unit to the first input/output of a control device, and the second input/output is connected to an operator's panel, and the third input/output is connected through a second interface unit to external devices or systems. Each measurement module has vibration sensors and temperature sensors, connected to an analogue-to-digital converter whose output is connected to a controller which is connected to the data bus through an interface unit.
EFFECT: high reliability of acceptance tests.
