Panel Elektro Substation Protection and Control Panels bring protection, control, metering, monitoring and communication functions together for high- and medium-voltage substations and switchyards according to project requirements. Control and Relay Panels (CRP), relay protection panels and related substation secondary systems can be engineered in 19-inch rack or standard floor-standing structures with project specifications, site conditions, equipment layout and customer approval processes taken into account.
Panel Elektro has manufacturing experience in international projects involving control, monitoring and signalling applications for Gas Insulated Switchgear (GIS) up to 400 kV. Panels are configured according to project specifications, site conditions and customer approval processes.
The physical design can be implemented in 19-inch rack cabinets or standard floor-standing panel structures according to architectural and equipment-layout requirements. Device arrangement, accessibility, wiring and testing requirements are addressed on a project basis.
Protection relays, Automatic Voltage Regulation (AVR), metering equipment, trip/close circuits, alarm and signalling components can be integrated within the same panel system according to project requirements.
Control, metering and signal connections from circuit breakers, disconnectors, transformers and other field equipment can be organized in marshalling cabinets and routed to the relevant protection and control systems, SCADA (Supervisory Control and Data Acquisition) or RTU (Remote Terminal Unit) systems. Depending on project requirements, integration with IEC 61850-based substation automation and communication infrastructures can also be provided.
Substation protection and control panels can be configured for different applications according to protection, control, metering, field-connection and communication requirements.
Solutions combining protection relays, trip/close circuits, signalling equipment and, depending on the project, Swing-Door control panels to support protection and control of substation and switchgear equipment.
Control panels that bring together the control, monitoring, signalling and auxiliary circuits of Gas Insulated Switchgear and, depending on project requirements, can also include interlock functions and field-status signals.
Metering panels for monitoring network parameters, AVR panels supporting transformer tap management, and substation automation, telecom or SCADA panels for data transfer between systems and control locations.
Distribution boxes configured according to site conditions, together with relay desks and control consoles used in substation control rooms.
