Application of Numerical Programmable
Relays
Numerical programmable relays contain many of
the functions discussed in this guideline in a
single package. Figures 34 through 37 show the
BE1-GPS100 and BE1-CDS220 applied to
generator protection. Due to logic complexity, full
details are not shown. Details of these applica-
tions may be found in the respective instruction
manual.
