B-PRO Bus Protection Relay
Source: APT Power Technologies (a NxtPhase business)
Provides bus and substation differential protection (low impedance), integrated breaker failure and overcurrent protection with metering and fault oscillography
Features:
- Provides bus and substation differential protection (low impedance), integrated breaker failure and overcurrent protection with metering and fault oscillography.
- Six sets of CT inputs for differential protection (18 currents) using a percentage slope characteristic for security or external faults.
- Overcurrent and breaker failure for each input current. Directional control of overcurrent functions are available. Plus, over/under bus voltage and frequency functions.
- Two separate differential zones — bus and transformer.
- High quality recording — fault recording (96 samples/cycle) and event logging.
- Metering functions for each input connection.
- Protection functions include IEEE devices, 87B, 27, 59, 60, 81, 87T, 50LS, 50BF, 50/51/67, 50N/51N/67, 46/50/51/67.
