–
Use for Inadvertent Energization logic or
On line indication or
Phase fault protection or
User-defined purpose
• 50TN: Ground Inst. / Def. Time
– Use for Inadvertent Energization logic or
– Ground fault protection or

Protection - Current
• 51N monitoring Optional Independent
Ground Input can act as OC differential.
• For those applications requiring
Generator Differential (87):
Use the BE1-87G or the BE1-CDS220
– Redundancy gained by placing the
differential in a separate package avoids
the “all your eggs in one basket” pitfall
