SwitchboardS and Variable Frequency driVeS

Borets Switchboards and Variable Frequency Drives (VFDs) are designed for control, protection and monitor-ing of ESP system parameters. They use state-of-the-art technologies and components that allow the ESP system to be better adapted to well conditions.

Switchboards and VFDs ensure power supply to the circuit “Transformer – Downhole Cable – Submersible Motor” and allow for capturing data from submersible equipment in order to maintain and adjust operational condi-tions in changing downhole environment, as well as to prevent downhole equipment from failures.

Borets offers the following switchboards and VFDs:• Direct Start Switchboards• Soft Start Switchboards• VFDs which are designed to control permanent magnet motors• Universal VFD to control both permanent magnet motors and

induction motors.

direct and Soft Start Switchboards

These switchboards perform a large number of control and protection functions, and have an accessible configuration. Direct and soft start switchboards are equipped with a storage device that enables performance data of the ESP system to be recorded on a real time basis and any modifications of the ESP system settings to be captured, including the date and time of such modifications. These data can be downloaded via a COM-PORT to a PC or to a parameter reading and entry device, transmitted to the SCADA system via a special interface or downloaded to a flash memory via a USB port.

Industry standard Mechanical and Electrical interlocks and protective devices provide a high level of safety for the operator including separate compartments for high and low voltage. All voltage ranges use vacuum contac-tors and fused PTs for the protection of equipment and fast-acting disconnect in the event of a fault.

«borets-***» SwitchboardsThese switchboards are supplied with Kaskad 2-200 motor controller that has four levels of protection to

prevent non-authorized modification of settings. It is equipped with an integrated LCD and nonvolatile memory.All enclosures are rated for outdoor use as IP43. Operating temperatures range from -60°C to +50°C.

Variable Frequency drives

Variable Frequency Drives provide maximum flexibility to adjust downhole system to changing operating conditions. As a result, maximum system run life can be assured while optimizing production rates.

The application-specific custom firmware provides optimum control with user-friendly adjustments, including frequency, acceleration and deceleration rates, auto restart, retries and delays and stopping methods.

Borets VFDs are equipped with state-of-the-art Sine-Wave Filter technology to produce the smoothest wave-form output with minimal harmonic content, thereby minimizing harmful electrical stress to the motor, power cable and other electrical components.

Benefits• Provides flexibility to match ESP parameters with changing well conditions for optimized system perfor-

mance and maximum production• Continuous ESP system operation in case of power supply loss - up to 2 seconds (for ESP system with

check valve)• Automatic gas locks removal by changing frequency when under load occurs• Enhanced remote monitoring, communication and control capabilities with the use of downhole sensors• Ability to adjust speed as equipment wears to maintain production or extend run life to minimize downtime

waiting on replacement equipment• Maximum starting torque in the «start current limitation»• Backspin braking with the possibility of setting frequency of backspin interception• Accelerated fluid drain from tubing (for ESP system without check valve) after pump stop

universal borets-Vd***u VFdUniversal Borets-VD***U VFDs are designed to control both permanent magnet motors and induction motors.

These VFDs utilize various control modes for both electric submersible and progressive cavity pumps.The following additional devices can be installed in the VFD on Customer request: a GPRS modem, backspin

limiter (for ESPCPs), power meter, downhole sensors, etc. Universal VFDs feature automatic determination of the type of the downhole sensor supplied by most of manufacturers. Permanent memory for storing well operation data is 100 Mb with a potential for further increase. The VFDs are compatible for connection to oil production con-trol and monitoring networks (RS-485, Ethernet). Data stored in the VFD’s memory can be downloaded via a USB interface. Hardware allows the controller to be modified by means of periphery devices and interfaces.
