High Tension Panel

Designing for higher voltage levels is not something that just happens; rather, designing for higher voltage levels is a strict design consideration due to the speed at which clearances, heat, and fault energy increase the further you are from the point of energization. A High Tension Panel is constructed to take control of the above items by providing properly controlled switching, reliable isolation and stable protection throughout the major feeders of primary distribution. To us at Perfect Automation & Innovation, the High Tension Panel represents a long-term asset for primary distribution, not just another piece of equipment to install.

The High Tension Panel complies with the appropriate compartmentalization / segregation of busbars, breakers, cables, and control sections. This compartmentalization / segregation allows for the performance of inspection work on a live circuit while continuing to provide electrical energy to adjacent circuits. Vacuum type or SF6 switching equipment are selected based upon duty cycle and system fault ratings only, not on the voltage rating alone. The configuration of the protection relays is based on real-world conditions within the electrical network, assuring that the tripping features of the protection relays are selective in operation and that the supply remains healthy to the upstream supply circuit.

The sizing of busbars is designed for continuous thermal capability and minimizes stress points by utilizing rigid supports. Space for termination of cables is provided at a practical rate with respect to both large diameter HT cables and a safe bending radius. Interlocked logic prevents the operator from operating under unsafe conditions, which is important during times of maintenance related shutdowns.

The provisions for an SCADA interface, metering and remote monitoring, enable and enhance the capabilities of today's electricity-based industries, or utilities, where human monitoring is not sufficient.

The High Tension Panels are utilized in Substations, Process Industries, Infrastructure Projects and Major Commercial Installations. The characteristics that define reliability of these systems include: Controlled Incoming Power, Fast Fault Clearing, Long Service Life.
