Lightning Surge Arrester for Type 1+2 Protection
Lightning strikes and power surges can cause significant damage to electrical systems and connected equipment. To safeguard against these threats, a Type 1+2 Lightning Surge Arrester provides comprehensive protection by combining the benefits of both Type 1 and Type 2 arresters.
What is a Type 1+2 Lightning Surge Arrester?
A Type 1+2 Lightning Surge Arrester is a hybrid device designed to protect electrical installations from direct lightning strikes (Type 1) and transient overvoltages (Type 2). This dual functionality makes it an ideal solution for buildings, industrial facilities, and critical infrastructure where both types of protection are required.
Key Features of Type 1+2 Surge Arresters
These arresters offer several advantages, including:
- Combined Protection: Handles both direct lightning strikes and induced surges
- High Discharge Capacity: Can manage large surge currents up to 50kA (10/350μs)
- Fast Response Time: Reacts within nanoseconds to divert dangerous surges
- Compact Design: Single-unit solution for space-efficient installation
- Visual Status Indication: Allows for easy monitoring of device condition
Applications of Type 1+2 Protection
These hybrid arresters are particularly suitable for:
- Buildings with external lightning protection systems
- Industrial plants with sensitive electronic equipment
- Telecommunication facilities
- Power distribution panels
- Critical infrastructure installations
Installation Considerations
When installing a Type 1+2 arrester, consider:
- Proper grounding is essential for effective protection
- Installation should be performed by qualified personnel
- The arrester should be placed as close as possible to the service entrance
- Regular maintenance and testing are recommended
Benefits of Combined Type 1+2 Protection
By choosing a combined Type 1+2 arrester, users gain:
- Simplified system design with fewer components
- Reduced installation space requirements
- Cost savings compared to installing separate devices
- Seamless coordination between protection levels
- Compliance with international standards (IEC 61643-11)
For comprehensive protection against both direct and indirect lightning effects, a Type 1+2 Lightning Surge Arrester offers an efficient and reliable solution that meets the demands of modern electrical systems.
