10KV Power Station, Capacitor Type Lightning Arrester

Key Features & Benefits

- Dual-Function Design: Integrates both Surge protection and capacitive filtering capabilities in a single device, providing comprehensive overvoltage protection while helping to mitigate high-frequency transients.

- Rapid Response Time: Extremely fast operation response (nanosecond-level) ensures immediate conduction when overvoltage occurs, effectively limiting voltage spikes to safe levels.

- High Energy Absorption Capacity: Robust design capable of absorbing and dissipating substantial surge energies from direct and indirect lightning strikes, as well as switching operations.

- Excellent Protective Characteristics: Low residual voltage ratio ensures that protected equipment experiences only minimal overvoltage during surge events, significantly extending equipment lifespan.

- Stable Performance: Maintains consistent protection characteristics throughout its service life with minimal performance degradation under normal operating conditions.

- Multiple Mounting Options: Suitable for various installation configurations including pole mounting, platform installation, and structure mounting in power station environments.

 Operating Principles

The capacitor-type arrester operates on the principle of nonlinear resistance combined with capacitive characteristics:

- Under normal operating conditions, the arrester presents high impedance to the system voltage

- When transient overvoltages exceed the arrester's triggering level, its impedance dramatically decreases, providing a low-impedance path to ground for surge currents

- The capacitive component helps in filtering high-frequency noise and provides additional stability to the protection system

- After the surge passes, the arrester automatically returns to its high-impedance state, ready for the next event

 Installation & Maintenance

- Installation Position: Should be installed as close as possible to the equipment being protected, typically at the incoming line Terminals

- Connection: Connect between phase and ground using appropriate conductors and Connectors

- Grounding: Requires a low-impedance ground connection for optimal performance

- Clearance: Maintain proper clearance distances according to local electrical codes

- Regular Inspection: Visual inspection for physical damage, contamination, or tracking marks

- Periodic Testing: Recommended periodic testing of leakage current and functional status
