Surge Arrester in Substation is designed to control transient overvoltage occurring in high-voltage power systems. Installed near transformers, busbars, or incoming transmission lines, it diverts excessive voltage away from critical equipment before insulation stress occurs. This product supports stable operation of substations during lightning activity and switching operations. It remains active under normal system voltage conditions and responds immediately to abnormal voltage rises. By limiting surge energy at key protection points, it helps reduce electrical stress on transformers, switchgear, and associated substation components.
Features
1. High-Voltage Surge Diversion: Directs transient overvoltage away from substation equipment.2. Lightning Overvoltage Control: Limits voltage spikes caused by direct or nearby lightning events.
3. Switching Surge Handling: Controls overvoltage generated during system switching operations.
4. Outdoor and Indoor Installation Support: Suitable for various substation layout requirements.
5. Continuous Operating Capability: Remains active under normal system voltage conditions.
6. Insulation Stress Reduction: Helps maintain acceptable voltage levels across protected equipment.
Advantages
1. Transformer Protection Support: Reduces surge-related stress on power transformers.2. Substation Equipment Safety: Helps protect switchgear and busbar systems from overvoltage.
3. System Voltage Control: Supports controlled voltage conditions during abnormal events.
4. Reduced Outage Risk: Helps lower the likelihood of equipment failure caused by surges.
5. Suitable for High-Voltage Networks: Designed for medium and high-voltage substation systems.
6. Long-Term Field Operation: Supports repeated surge exposure over extended service periods.
Applications
1. Power Substations: Installed at critical protection points within substations.2. Transformer Protection Zones: Limits overvoltage at transformer terminals.
3. Transmission Line Entry Points: Controls incoming surge energy from overhead lines.
4. Busbar Systems: Protects substation busbars from transient voltage rise.
5. Outdoor High-Voltage Installations: Suitable for exposed substation environments.
6. Grid Upgrade Projects: Adds surge protection during substation expansion or renewal.
