Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown ...

So there I was with this mystery transformer on which someone put a label showing three different speaker load impedance, but with no indication of what the intended primary winding impedance happens ...

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 ...

In response to the growing demand for compact substation test systems that are capable of performing a wide range of tests, Megger has developed TRAX test sets. Combining versatility with ease of ...

Dual-band impedance transformers and matching networks are pivotal components in modern high-frequency systems, facilitating efficient power transfer between disparate circuit elements by converting ...

Today’s electronic equipment must be designed to, first, operate in the electromagnetic (EM) environment it is to be employed in, and second, ensure that the EM fields generated by the system do not ...
