Purpose and field of application | |
|
ELEKTON-TMS-28 is designed to operate with motors type SLB-Maximus. Main field of application:
automation of electric drive operating modes for oil production equipment. Elekton-TMS-28
downhole monitoring system is designed to control, record and transmit to external devices
current values of the following parameters:
- ESP motor oil temperature;
- electric submersible motor oil pressure;
- formation fluid temperature;
- electric submersible motor stator temperature measured by a separate thermocouple J-type sensor;
- vibration acceleration on X, Y and Z axes;
- insulation resistance of the circuit "neutral point of DHS HV star-connected winding – ESP cable – neutral point of ESP motor star”.
The system remains operative with the cable length up to 6000 m.

Notes:
1) For insulation resistance, the error will be determined relative to the measured value, for other parameters
– relative to the upper range limit.
2) For vibration acceleration range from 10 to 70 Hz.
