5 Common Surge Arrester Failures and How to Diagnose Them

Your surge arresters are the silent guardians of your power system, deflecting lightning strikes and switching surges around your critical assets. But what happens when the guardian fails?

3 Tips to Choose the Right Surge Arrester for Renewable Energy Systems

In the era of renewable energy, protecting power systems from voltage surges is more important than ever. Whether you operate a solar power plant, a wind farm, or a battery storage facility, your equipment faces constant exposure to lightning and switching surges. This is where a Zinc Oxide (ZnO) Surge Arrester plays a vital role — safeguarding transformers, inverters, and switchgear from overvoltage damage. In this article, we’ll share three expert tips to help you choose the right surge arrester for renewable energy systems, ensuring long-term reliability, cost-efficiency, and compliance with international standards.

Maintenance Checklist for Auto Reclosers: How to Improve Grid Reliability

In today’s evolving smart-grid era, the role of auto reclosers cannot be overstated. These devices, often deployed in medium-voltage distribution networks, perform rapid fault isolation and reclosing to help restore power swiftly. Using a well-defined maintenance checklist for auto reclosers, utilities can significantly improve grid reliability, reduce outage duration, and support proactive maintenance strategies. In this article we’ll explore how to maintain vacuum-type auto reclosers (such as smart vacuum auto reclosers compliant with IEEE C37.60 and IEC 62271-111) with a structured approach to support bulk procurement and customers decisions.

The Crucial Role of Auto Reclosers in Modern Power Distribution

In modern power distribution networks, improving reliability and minimising downtime are top priorities. Overhead distribution lines are particularly prone to transient faults, such as lightning strikes, tree branches, or animal contact, which often resolve themselves. Studies indicate that up to 80% of faults in overhead networks are temporary. Auto Reclosers, also known as Automatic Circuit Reclosers (ACRs), are designed to address these challenges. They can detect faults, isolate affected segments, and automatically attempt reclosing, restoring power without human intervention. This blog explores the working principle, application, benefits, selection criteria, and implementation considerations for Auto Reclosers, providing power engineers and grid operators with comprehensive guidance.
