SYNOPSIS SYNOPSIS
• In conventional distribution system , if fault occurs CB trips and blackout over a large region occurs, the faulty segment is not precisely identified.
• If we add fault detection relays the system is able to detect fault location.
• In data

PCD2000 - Advanced Protective FunctionsPCD2000 - Advanced Protective Functions
Under/Over Voltage control and alarming*– Very useful for detection of high side fuse operation/ single phasing condition– Also used for loop sectionalizing, voltage transfer– Allows time delayed load shedding
Under/Over Frequency control and alarming* (1phase or 3 phase)– Allows enhanced load shedding capability
Directional specific overcurrent protection*– Allows for closed loop schemes
Directional specific power flow control*– Allows for changing to alternate profile during backfeed condition
Directional specific overcurrent protection*– Allows for closed loop schemes
* Requires voltage inputs

Soon to be released:Soon to be released:
• Single phase tripping– Very advantageous for residential loads– Reduces affected customers by 2/3 rds – Single or three phase lockout selection– Option to block ground tripping after single phase trip/lockout– Can change to three phase trip only based on KW demand
threshold
• Loop Scheme automatic reconfiguration (10/99)– Does not require communications between units or master– One control used for both main feeder and tie (or midpoint)
reclosers– Has separate user interface with per phase voltage indication
recloser status and override.
