- 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
14PCD2000 MeteringAccuracy of Volts and Amps to 1
Requires Voltage Inputs
15PCD2000 - Data records

- Up to 160 days of data
- Records kW, kVAR volts per phase
- Operation/Fault Records
- 128 recloser operations
- Fault duty accumulator for interrupters
- Operation and trip counters
- Fault records
- Records detailed fault data for last 32 faults
(including relay times, distance to fault) - Basic fault data for last 128 faults
16PCD2000 - Advanced Data records
- Oscillographic capture
- Valuable tool for analyzing post fault waveforms
- Records total of 64 cycles per phase currents and
voltages 8 distinct events - Power Quality records per ANSI/IEEE 1159 Standard
- Very powerful tool for pinpointing source of
power quality problems - Records voltage sags, swells, Total Harmonic
Distortion, Total Demand Distortion - Can use ANSI recommended voltage/duration
thresholds or can be user specified - Holds up to 256 records
17PCD2000 Communication Features
- Open protocols, DNP3.0, Modbus ASCII RTU
included with each unit - Doesnt require additional hardware for protocols
- RS232, RS485, programmable I/O and optical port
are all standard. Fiber port is optional - Fiber port is unsurpassed, fully regenerates
signal, preventing signal attenuation - Software for the PCD2000, WinPCD, has dial up
capability and an extensive control interface - Control Cabinet has plenty of room for a radio or
modem, and a 12 V DC power supply is optional
18Soon 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.
