The NxtPhase B-PRO 8701
provides bus & substation differential protection
(low impedance), with CT saturation control, integrated
breaker failure & overcurrent protection with metering
& fault oscillography. Application for 2 to 18 bus
connections using three single phase B-PRO relays model
8701/BUS.
Overcurrent & breaker failure for each input current.
Directional control of overcurrent functions are available.
Plus, over/under bus voltage & frequency functions.
Two separate differential zones - bus & transformer.
High quality recording - fault recording (96 samples/cycle)
& event logging.
Metering functions for each input connection.
Easy to use, simplified relay setting & record analysis
software (Windows 9x/ME/NT/2000) included.
Intuitive ASCII-terminal interface provides full local
or remote access.
Substation automation ready.
The B-PRO Bus Protection
Relay features:
Protection functions include IEEE devices, 87B, 27,
59, 60, 81, 50LS, 50BF, 50/51/67, 50N/51N/67, 46/50/51/67.
ProLogic - control logic statements.
Three communication RS-232 ports. Internal modem option.
Direct-connect DNP3 & Modbus SCADA communication
protocols (Ethernet ready).
IRIG-B time stamping & sample synchronization. |
