The electrical grid network is oftentimes classified as critical infrastructure. For electrical utilities, any disruption which leads to major downtime is a major source of revenue loss. Furthermore, policymakers today expect network operators to deliver 24/7 electricity to the retail consumers. As a result, it is important that electrical equipment have the highest standards of …
In our previous post, we deep-dived into the various techniques and methodologies that are widely adopted for assessing the healthiness of Lightning/Surge Arresters. In this post, we will answer the 10 frequently asked questions (FAQs) on the various aspects of testing and measuring Lightning/Surge Arresters. Let’s begin! FAQs: 1. What are Third Harmonics? A. In …
