The Edison idea iDP is a substation IED (Intelligent
Electronic Device) designed for Distribution Feeder
Protection, Monitoring and Control.
PROTECTION FEATURES
The Edison idea iDP provides complete feeder
protection. Several different scheme files are
available for a variety of overcurrent relay applications.
Available protection functions include:
Phase, Ground, and Negative-Sequence
instantaneous, definite time, and inverse
time overcurrent
Directional phase and ground elements
Multiple-Step over/under frequency elements
Over/under voltage elements
Multiple-Shot programmable reclosing
Sync-check
Reverse Power
Breaker fail-to-trip and fail-to close detection
Fuse-Fail detection
Incipient Cable Splice Failure detector
Breaker monitoring
Get Advance Notice of Pending Cable Faults with the ICSF Detector (Patent Pending)
Most cable splice failures are caused by water ingress. This ingress results in repeated
faults of very short duration. By detecting the waveforms associated with these faults,
it is now possible to give your maintenance crews advance notice that a fault is imminent
and allow them time to perform preventative maintenance, saving costly unplanned outages.
The Edison Idea iDP-210 is a full featured feeder protection relay that includes
the Incipient Cable Splice Failure (ICSF) detector algorithm.
