Should You De-Energize Transformers When Changing Taps?
Since the input power fed into a transformer may be lower or higher than the intended rate, transformers require adjustments to produce the correct secondary voltage. These fluctuations can occur for various reasons, including a power drop across a long distribution line or excessive consumption from one or more facilities. Since it is impractical and […]

Custom Bus Work on Transformers
When you purchase a replacement or retrofit transformer, most likely its high-voltage and low-voltage connections will not line up perfectly with your existing infrastructure due to differences in transformer models, ratings or designs. Low-voltage bus bar connections must line up perfectly with matching bolt holes and fasten together without distorting forces to ensure maximum conductance and prevent arcing. Each installation configuration is […]
