IRZ-200 series ESP switchboards

Parameters monitoring, control and protection of 3 to 250 kW electrical submersible motors.

Advantages

  • small overall sizes and weight
  • easy operation and maintenance
  • easy connection
  • 4-line display
  • history download to USB drive
  • software updating without submersible electric motor operation interruption
  • compliance with LUKOIL, ROSNEFT, SURGUTNEFTEGAS, GASPROMNEFT companies requirements and GOST R51321.1-2007 standard
  • bus design of power systems (applicable for drives with current rating over 250 A)

IRZ-200 ensures

  • motor control in manual or automatic mode
  • continuous control of supply voltage, order of phase sequence, currents in three phases and isolation resistance of the “pump transformer — power cable — motor” link
  • calculation of voltages and currents unbalance, power factor, load factor, consumed power, operation time
  • connection to ground acquisition units produced by IRZ TEK and other manufacturers
  • record of controlled parameters and causes of SEM motor switch offs in real time and saving of the records during power supply interruptions
  • protection of equipment against emergency modes caused by failures in electric mains and submersible equipment.

After actuation of the protection system, the station automatically restarts when parameters return to the working range.

The switchboard

  • enables connection of appliances with 220 V rated voltage and up to 10 A consumption current to a female connector on the operator’s panel of the station
  • can be integrated into oilfield telemechanics (normally closed and normally open contacts)
  • can be connected to a SCADA-system via RS232 or RS485 interfaces using the Modbus-RTU communications protocol
  • has a GPRS-modem to transmit data via Internet

The switchboard can be equipped with a power metering system registered in the State Register of Measuring Devices (Russia) upon request.
