SD Engineers offers high-performance 11 kV and 33 kV Indoor VCB Panels designed to provide comprehensive overload, short-circuit, and earth-fault protection for distribution transformers and other HT equipment.Manufactured in accordance with stringent industry standards, these panels deliver robust durability, enhanced safety, reliable performance, and cost-effective operation.
SD Engineers designs and manufactures
High-performance 11 kV and 33 kV Indoor Vacuum Circuit Breaker Panels for the safe switching, protection, control, and monitoring of medium-voltage power distribution systems.
These panels are suitable for incoming and outgoing feeders, power and distribution transformers, bus couplers, metering feeders, and other industrial HT applications. The integrated vacuum circuit breaker provides dependable interruption of normal and fault currents within the panel’s approved ratings, while numerical protection relays safeguard the electrical system against overcurrent, short-circuit, and earth-fault conditions.
Each VCB panel is engineered according to the approved single-line diagram, system voltage, load requirements, fault level, utility guidelines, and project specifications. The protection scheme, metering arrangement, busbar configuration, cable-entry direction, interlocking logic, and communication requirements can be customized for the application.
KEY FEATURES & HIGHLIGHTS
• Reliable Vacuum Switching Technology
High-performance vacuum circuit breakers provide dependable switching, long service life, and reduced maintenance requirements.
• Comprehensive Protection System
Numerical protection relays can be configured for overcurrent, short-circuit, earth-fault, transformer, feeder, and other application-specific protection functions.
• Robust Metal-Enclosed Construction
Available with compartmentalized metal-enclosed construction for safe operation, convenient maintenance, and dependable performance in industrial environments.
• Mechanical and Electrical Interlocking
Interlocking arrangements help prevent unsafe operation of the circuit breaker, isolating mechanism, earthing switch, and access doors.
• Metering, Control and Indication
The panel can incorporate CTs, PTs, multifunction meters, control switches, annunciation, status indication, trip-circuit supervision, and energy monitoring.
• SCADA and Remote Communication
Optional communication facilities can be provided for SCADA integration, remote monitoring, event logging, fault recording, and centralized control.
