I found a passage is a book I've been reading that is a perfect example of "the more things change the more they stay the same." Anybody want to venture a guess as to how old this passage might be?
In recent years the complexity of relay problems has increased immeasurably with the expansion and interconnection of power systems. Many large companies have found it necessary to revise completely their major relay systems. To meet the more involved operating conditions, relays must be fundamentally more accurate; applications by the method of complete short-circuit studies for steady state and, in special cases, transient conditions must be made. Field tests must be carefully made, and attention must be given to the characteristics of auxiliary devices, current transformers, potential devices, etc. In brief, all errors entering into the operation of the relays should be thoroughly understood and corrected, or allowance made where complete correction is not practical.
