What are electrical steels?

In rail-related applications, electrical testing is not only essential to prove the safety and reliability of new and modified electrical systems, it can also be a valuable tool for the prediction and prevention of costly failures.

While user requirements for protective relay test sets have of course, evolved over the years particularly with the advent of substations designed around the new IEC 61850 networking system, the basic factors driving developments today remain the same as...
