FUNCTIONALITY
CSSPSS’s HT Panels serve as the primary nodes in high voltage distribution networks, functioning as the central point for receiving and redistributing electrical power at 11kV, 22kV, or 33kV. Equipped with Vacuum Circuit Breakers (VCBs) or SF6 breakers, these panels control the flow of power and isolate faults instantly to protect expensive transformers and downstream equipment. The integrated protection relays continuously monitor system parameters, tripping the breaker in milliseconds upon detecting overcurrent, earth faults, or other anomalies, thereby ensuring grid stability and personnel safety without manual intervention.

Frequently Asked Questions
HT (High Tension) panels handle high voltage levels (above 1kV, typically 11kV, 33kV), used for primary power distribution. LT (Low Tension) panels handle low voltage (below 1kV, typically 415V) for end-user distribution. HT panels require stricter safety clearances and specialized switchgear like VCBs.
Most modern HT panels use Vacuum Circuit Breakers (VCBs) for voltages up to 33kV due to their reliability, low maintenance, and eco-friendliness. SF6 (Sulfur Hexafluoride) breakers are also used, particularly for higher voltages or specific applications, though VCBs are becoming the industry standard.
Our HT panels include arc-resistant enclosures, safety interlocks (to prevent wrong operation), insulated busbars, numerical protection relays for fault detection, and earth switches. We also provide proper clearances and safety labels as per IEC standards.
Yes, HT panels require periodic maintenance by trained professionals. This includes cleaning of busbar insulators, checking breaker vacuum integrity, lubricating mechanisms, and testing protection relays. CSSPSS offers comprehensive AMC services to ensure your HT infrastructure remains in top condition.
