Lighting (Surge) Arrester

A lightning (surge) arrester, also known as a surge protection device (SPD), is an essential component in solar power Plant designed to protect electrical equipment from voltage surges caused by lightning strikes and switching operations.

Lightning (surge) arrestors are vital for the protection and efficient operation of solar power Plant. By safeguarding against voltage surges caused by lightning and other transient events, these devices protect sensitive electrical equipment, enhance system reliability, ensure safety, and provide significant cost savings over time. Properly installed surge arrestors are essential for maintaining the integrity and performance of solar power installations, especially in regions prone to lightning activity. Here's an overview of its features and benefits:


Features of Lightening (Surge) Arrestors

1

High Energy Dissipation:

Surge Protection: Capable of dissipating high energy voltage spikes and surges, protecting sensitive equipment.
Varistor or Gas Discharge Tube (GDT): Typically employs metal oxide varistors (MOVs) or gas discharge tubes that respond rapidly to surges.

2

Voltage Clamping:

Clamping Voltage: Limits the voltage that appears at the terminals of protected equipment by clamping it to a safe level.
Fast Response Time: Reacts quickly (in nanoseconds) to transient over voltages to prevent damage.

3

Multiple Stages of Protection:

Primary and Secondary Protection: Often installed in multiple stages to provide layered protection, ensuring any residual surge is further reduced.

4

Durability and Robustness:

High Durability: Designed to withstand multiple surge events without degradation.
Weather Resistant: Typically enclosed in weatherproof housing suitable for outdoor installation.

5

Easy Integration:

Compact Design: Compact and modular design for easy integration into existing electrical systems.
Compatibility: Available in various voltage ratings and configurations to match different system requirements.
