Transformer bushings explained: Types, working principle, failure causes & maintenance best practices
Electrical power systems are equipped with critical assets such as power transformers, and even a small failure can lead to costly downtime. That's where transformer bushings come in. Transformer bushings play a very important role in safely transferring electrical energy through grounded transformer tanks. In this blog, we will discuss how they work, their types, and the best maintenance practices to improve performance. What are transformer bushings? Transformer bushings are insulating structures that allow electrical conductors to safely pass through grounded barriers such as transformer tanks. In short, they prevent electrical leakage. They are crucial for proper insulation between energized conductors and grounded metal parts. These bushings offer protection from: Insulation breakdown Short circuits Severe operational failures How do transformer bushings function? Bushings are designed to carry high-voltage current...
