CONTROL PANELS

Automatic Changeover Switching Equipment (ACSE): The automatic control function is responsible for the automatic switching scheme and interlocks for breakers. In order to achieve this function, the intelligent electronic device (IED) collects inputs for breaker status, protection relays, and other data related to power such as voltage and volt-ampere reactive (VAR) values. This function is derived from the same IED used in the panel to divert the control through the supervisory control and data acquisition (SCADA) system.

Automatic Bus Transfer Scheme (ABTS): The automatic bus transfer scheme (ABTS) is an automatic switching scheme in substations which performs in parallel with some transformers. In the event of a power transformer failure, the remaining transformers continue to operate to feed the entire substation load without interruption of supply. The ABTS scheme can be achieved through a programmable intelligent electronic device (IED) or remotely controlled through the supervisory control and data acquisition (SCADA) system.

Automatic Capacitor Control System (ACCS): The automatic capacitor control system (ACCS) provides automatic control for capacitor banks to improve the power factor and reduce the volt-ampere reactive (VAR) value in the network, thereby helping to reduce losses in power lines, the control logic performed by gathering voltage, current, and breaker status of the busbar and the incomers. This control can be achieved through a programmable control intelligent electronic device (IED) which can calculate the VAR values and drive a logic based on these values.

Automatic Voltage control (AVC / RTCC): Automatic voltage control monitors the voltage of a power transformer and keeps the load voltage in the controlled setting value. This control is performed using a control intelligent electronic device (IED) which sends control output to a tap-changer for the transformer. A signal can be sent to raise or lower the tap, depending on voltage setting.

LOCAL CONTROL PANELS

We are the largest manufacturer of local control panels for gas-insulated switchgear in KSA. All our local control panels are compatible with gas-insulated switchgear from international manufacturers.

SPECIAL PANELS

Annunciator & Marshalling Kiosk Panel: These panels are used to display substation signals and provide continuous signal recording and printing.

Mosaic Control Panel: This device is used to control switching equipment and the measurement of energy in all bays. The control and indicator arrangement are constructed of mosaic tiles on the front side of the panel. The use of tiles allows for easy modification and bay extension for future expansion.

Metering Panels: These panels are used to measure energy for tariffs.

Data Retrieval / Station Evaluation Panel (DTR/SEP): The DTR/SE Panels relay in all panels to ensure seamless communication through one system. It is used to download and upload data from remote area protection and measurement equipment at a master station headquarters.

Programmable Logic Controller (PLC) Panels: Our programmable logic controller panels feature sophisticated programming logic using the most popular PLC brands. These PLC panels are approved for SCADA systems by the largest utility in Saudi Arabia.

Interposing Relay Panels (IRP): An interposing relay panel is used to send signals and status between the control center and electrical components such as motor control centers, motors, pumps, lighting, and so on.
