What is an Open Delta Transformer

TITLE

In three phase systems, the use of transformers with three windings (or legs) per side is common.  These three windings are often connected in delta or star, resulting in common transformer configurations such as delta-delta or delta-star.  An open delta transformer is a special arrangement which uses only two windings......Read More..

Generator Sizing & Operation Limits

TITLE

When selecting a generator, there are inherent limits on the active and reactive power which can be delivered. Generators are normally sized for a certain kW at a power factor of 0.8. However, to understand the operation fully, it is necessary to look at the generator reactive power curve....Read More..
