Your typical government building or privately owned buildings do not use LTC’s. You could even say that businesses that do not own the extra space […]

Medium Voltage Cable / 15kV Terminations

Medium Voltage Cables Electrical wire is an integral part of our lifestyle. Whether you care to notice or not, copper/aluminum conductors are everywhere. They provide power to every business and home that wishes to be connected. Most of the time, people who aren’t in the electrical trade, tend to see overhead power lines. Those consist […]

Transformer Vectors

Transformer Vectors   This was a topic brought up on the job and I figured I would address it in a very general post. This will not go too in depth but will help you understand how a vector is configured and possibly understand what you are dealing with on the job.   What is […]

Transformer Snubber Assembly

What is a Transformer Snubber?   It is a set of capacitors, surge arresters, fuses, and resistors typically found on medium voltage dry type transformers.   What are Snubbers designed for?   The main application has been to reduce damage to transformers during energizing applications. Energizing medium voltage transformers produces transient voltages. These transient voltages […]

Transformer Oil Samples

Transformer oil – what is it?   Transformer oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Typical motor oil that most people think of, is not the type of oil in a transformer. Transformer oil keeps the transformer cool. It also insulates the transformer and allows electrical components to be […]
