A common summer thunderstorm nearly turned into a regional power supply disaster. Recently, along an important 500-kilovolt transmission corridor in a certain province, a rare explosive damage occurred to an operating zinc oxide arrester in a hub substation due to the lightning overvoltage. The loud noise not only completely destroyed the arrester but also caused […]
Insights from Industry HeadlinesRecently, numerous countries have announced unprecedented investment plans for grid infrastructure. For instance, in early 2024, the U.S. Department of Energy unveiled a $10.5 billion “Grid Resilience and Innovation Partnerships” program, focusing on modernizing transmission lines and large power transformers. Simultaneously, the EU’s “RepowerEU” strategy and China’s 14th Five-Year Plan for a
News BackgroundAccording to a May 2024 report in The Times of India, severe pre-monsoon thunderstorms have caused massive power outages across northern India, particularly in Uttar Pradesh, Punjab, and Rajasthan. Lightning strikes triggered multiple 400kV transmission line failures and damaged equipment at several crucial substations. Power department officials indicated that voltage surges caused by lightning
The News Event:Last week, Storm “Pierrick” swept across the United Kingdom, bringing severe gales and torrential rain to northern regions. According to reports from BBC News and energy network operators, the storm caused significant power outages for thousands of homes in Scotland. Beyond the obvious damage from fallen trees on power lines, energy providers noted
