Surge Arrester FAQ
Q: What is the typical lifespan of a Surge Arrester?
A: The average lifespan ranges from 10-15 years, depending on environmental conditions and surge exposure frequency. Our models feature durable metal oxide varistors with self-healing properties that extend operational life even after multiple surge events.
Q: How often should Surge Arresters be inspected?
A: We recommend visual inspections every 6 months and professional testing annually. Critical facilities should perform more frequent checks. Look for discoloration, cracks, or moisture penetration which indicate potential failure.
