HT Control Panel: Unwavering Control & Safety for High-Voltage Systems

The HT (High Tension/High Voltage) Control Panel is the indispensable heart of any high-voltage electrical distribution or control system. Engineered for paramount safety, reliability, and precision, our HT Control Panels provide robust control, monitoring, and protection for critical industrial and utility applications where substantial power is managed.

Designed to meet the rigorous demands of high-voltage environments, these panels ensure stable operation, protect valuable assets, and safeguard personnel, making them a cornerstone for efficient and secure power management.

Key Features

• Robust & Safety-Compliant Enclosure:
  • Constructed from heavy-gauge CRCA (Cold Rolled Close Annealed) steel or stainless steel for superior durability and corrosion resistance.
  • Available with high IP ratings (e.g., IP54, IP65) for excellent protection against dust, water ingress, and environmental hazards.
  • Designed with internal arc fault containment and pressure relief for enhanced personnel safety.
  • Equipped with robust locking mechanisms and interlocks to prevent unauthorized access and ensure safe operation sequences.
• High-Voltage Circuit Breakers:
  • Integrated with state-of-the-art Vacuum Circuit Breakers (VCBs) or SF6 Breakers for reliable switching and fault interruption at high voltages.
  • High breaking capacity suitable for severe short-circuit conditions.
  • Motorized spring charge mechanisms for remote operation and fast reclosing.
• Advanced Protection Relays:
  • Utilizes intelligent numerical/microprocessor-based protection relays (e.g., Siemens, Schneider, ABB) for comprehensive protection against:
    • Overcurrent (Phase & Earth Fault)
    • Under/Over Voltage
    • Differential Protection (for Transformers)
    • Restricted Earth Fault (REF)
    • Motor Protection (if applicable)
    • Frequency Protection
  • High-speed operation to minimize fault duration and prevent equipment damage.
• Integrated Metering & Monitoring:
  • High-accuracy digital multi-function meters for real-time measurement of voltage, current, power (active, reactive, apparent), power factor, and frequency.
  • Energy analyzers for monitoring consumption and quality.
  • Event logging, fault recording, and disturbance recording capabilities for diagnostics and root cause analysis.
• Intelligent Control & Automation:
  • Seamless integration with Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS) for automated control sequences, load shedding, and process interlocking.
  • Human-Machine Interface (HMI) touchscreens for intuitive local control, status visualization, and alarm management.
  • Provision for remote SCADA connectivity via standard communication protocols (Modbus RTU/TCP, IEC 61850, Profibus, Ethernet/IP).
• High-Quality Components:
  • Uses certified high-voltage components including current transformers (CTs), potential transformers (PTs), surge arresters, insulators, and busbars.
  • Copper or aluminum busbars, adequately sized and insulated for specified current ratings and short-circuit withstand.
• Safety Interlocks & Disconnectors:
  • Mechanical and electrical interlocks to ensure a safe sequence of operations (e.g., preventing breaker closure when the earthing switch is closed).
  • Load break switches, isolators, and earthing switches for safe maintenance and isolation procedures.
