Protective Relays
Features, Benefits and Functions
Applications
●
Provides reliable three-
phase and ground
overcurrent protection
for all voltage levels
●
Primary feeder circuit
protection
●
Primary transformer
protection
●
Backup to differential
protection
●
May be used where
instantaneous and/or time
overcurrent protection is
required
●
Ground element capable
of residual, zero sequence
or external source
connections
Protection Functions
●
