1.4 Description of VSD design
1.4.1 The drive constitutes a metallic cabinet that can be accessed on two sides.
Functionally the drive consists of a power section and control system.
1.4.2 The connection of the drive to the power supply network and to the load is made inside the main
circuit I/O compartments located on the rear side of the cabinet.
1.4.3 On the rear side of the cabinet, there are also compartments for connection to a telemechanics
system and to the step-up transformer Y-point, and a compartment of the frequency inverter.
1.4.4 The operator’s panel is located inside a separate lockable compartment on the front side of the
cabinet.
1.4.5 Design and operation of the control system
1.4.5.1 The control system consists of control units and IRZ-500 drive controller (hereinafter referred to
as “controller”).
1.4.5.2 The operator’s panel includes the following controls and indicators:
- Incoming power circuit breaker;
- controller with a USB connector for connection of USB-flash devices;

the drive according to the scheme in Annex B.
3.1.2 If it is necessary to install or replace a DHS surface readout unit inside the drive, the installation
should be performed according to the procedure specified in the VSD Operation manual.
3.1.3 At the first start of the drive, it is recommended to set the factory settings. Then enter or correct
the required list of settings in accordance with Table 3.1.

3.2 Emergency actions
The procedure of work at emergency ESP stops and abnormal modes of operation is as follows:
3.2.1 In case of a tripping caused by the insulation resistance protection function:
3.1.4 Check operation capability of surface equipment in idle mode (check the real-time parameters
and protections).
3.1.5 Perform a test run of the drive in the manual control mode and monitor on the controller display
that frequency is increased to 5 Hz.
3.1.6 While monitoring the value of motor current on the drive’s display, increase the frequency with
the step of 5 Hz.
3.1.7 If at a frequency of 10 Hz the overload protection or protection at inverter output short circuit
activates, perform the following actions:
- check that the step-up transformer and motor are connected properly;
- if the connection is correct, disconnect the cables in the drive output compartment and press the
START button, set the output frequency to 50 Hz;
- if the overload protection or protection at inverter output short circuit is not activated with the
disconnected cable in the drive output compartment, then the step-up transformer, Motor or Cable
may be damaged;
- if the step-up transformer, cable and motor are in good condition, contact the manufacturer’s service
department.
3.1.8 If the overload protection or protection at inverter output short circuit activates at 15-35 Hz
frequency, then the ESP is probably jammed. It is necessary to enable push or rocking start mode and
repeat the start attempt. Recommended setting values are given in table 3.2.
3.1.9 If the attempt to start the jammed ESP makes no effect, it is necessary to flush the well.
3.1.10 After reaching the required frequency and after 20-30 minutes of operation at a constant
frequency, it is recommended to perform automatic voltage optimization with respect to current. To
do so, set the control point “AUTO.OPTIMIZATION Un” to “ON”.
3.1.11 When selecting the PSI pressure units of measurement, select “PSI”in the “Pressure
measurement” item of the “DHS control points and protections”/ “DHS settings”menu, and set “0,1”
in the “multiplier” item.

IRZ 500 QUICK START
16
Check the insulation resistance control protection function for normal operation.
If a downhole sensor system surface unit is not used, the DHS TYPE control point shall have the “NO”
value; in the TRANSFORMER Y compartment of the drive, the XS12 connector shall be connected to
VR210.
If a downhole sensor system surface unit is used (no matter if the downhole sensor itself is used or
not), make sure that the downhole sensor system surface unit is not damaged and the settings of
communication with the downhole sensor system are correct; in the TRANSFORMER Y compartment,
the XS12 connector shall be disconnected from the VR210 unit.
Disconnect the ends of the cable of the downhole ESP unit from step-up transformer output terminals,
measure the insulation resistance with a megohmmeter and make sure that motor windings have the
same insulation value, visually check condition of the cable coming from step-up transformer terminals
to the well mouth (for reflow or mechanical damage).
3.2.2 In case of tripping caused by frequency inverter or sine filter overheating protection function:
Check the status of the SF4 “VENTILLATION” circuit breaker –it shall be in “On” position.
Check the status of venting holes and filters, clean when necessary.
Reduce PWM frequency, but it should not be lower than 4 kHz.
3.2.3 In case of tripping caused by the overload protection (OLP) function:
Check the drive OLP function for correct operation.
Check supply voltage in the phases at the low and high sides of the step-up transformer.
Using a 1000 V megohmmeter: check insulation resistance in the “TRANSFORMER - MOTOR” system
and make sure that motor windings have the same insulation value. If insulation resistance is not less
than 0.5 МΩ, start the ESP unit. Measure currents in the phases using a clamp meter at the high and
low sides of the step-up transformer. Phases distortion in terms of voltage and current shall not exceed
5%.
Check the ESP system for normal operation. The delivery parameters and dynamic level may change
and water cut may increase.
If load current exceeds its nominal value, stop the ESP system. Increase or decrease step-up transformer
voltage (by switching tapping in one or two steps).
After load current decreases till its nominal value, set optimized value of step-up transformer voltage,
adjust OLP, ULP and load level.
If load current fails to decrease till its nominal value, start the unit in the “push” or “rocking” mode.
If the ESP unit fails to start, perform additional maintenance operations (rinsing and others) or pull out
the ESP system.
If it is decided to pull out the ESP system, shut down the unit, disconnect the cable from terminal
contacts of the step-up transformer.
