Distribution transformers must adhere to NEC and NFPA 70 standards, with specific requirements for overcurrent protection, ...

Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...

Elsco Transformers reports that choosing the right transformer size involves calculating kVA based on voltage and current for ...

When comparing the kilovolt-amp demand loading on Southern Company substations with the actual connected transformer nameplate kVA, it was apparent that, on average, the distribution transformers were ...

Each turbine in a wind farm is equipped with a step-up transformer, which boosts (steps up) turbine generator output voltage from a few hundred volts to the collector system’s medium voltage ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...
