Do Oil-Filled Transformers Need a Containment Pan?
If your facility uses oil-filled transformers to convert energy and they contain more than 1,320 gallons of oil, you may be subject to the Spill Prevention, Control and Countermeasure (SPCC) Rule. The primary goal of the SPCC Rule is to contain oil discharges and prevent these discharges from reaching navigable waters and adjoining shorelines. Specific rules apply […]

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 […]

C-Rise Insulation Options for Dry Type Transformers
Because transformers convert power into higher or lower voltages, they generate heat as a byproduct. This heat causes increased temperatures in the transformer’s internal components, including the primary and secondary windings. A transformer’s temperature rise — or C-rise — is the average temperature of the windings in Celsius over the surrounding temperature when the transformer […]
