GE SR750-P5-G1-S1-HI-A20-RThis function allows automatic or manual blocking or raising of trip settings for a period after the breaker is closed. Built-in scheme available to perform main-tie-main transfer using a set of three relays, two on incoming and one on a normally open bus tie breaker. This scheme uses “ open before close “ sequence for safe operation. Manual Close Control After the breaker is closed manually, the relay can block any IOC element or raise the pickup value of any TOC element, each for a programmable time delay, after which normal operation is restored. Bus Transfer Scheme A set of three relays, two on incoming and one on a normally open bus tie breaker can perform transfer on loss-of-source. Recloser (760 Only) Autoreclosing can be initiated externally or from an overcurrent protection. Up to four reclose operations are possible, each with a programmable dead time. For each reclose shot, the relay can be programmed to block any IOC element, and to adjust the curve characteristics of any TOC element. The number of shots can be reduced by high currents. Equipment Management The following comprehensive features in the relay allows to manage the primary breaker: • Trip counter to keep track of number of operations • Per-phase breaker contact wear calculations for maintenance • Breaker failure detection • Trip coil monitoring Monitoring and Metering The 750/760 features advanced monitoring and metering functions which include: Fault Locator The relay uses captured data to calculate the type, distance to and the impedance of the fault. Records of the last 10 faults are stored. Breaker Conditions The relay calculates the per-phase wear on the breaker contacts to establish a threshold. When the breaker maintenance threshold is exceeded the relay can trigger an alarm. An alarm is also generated if the relay detects that the superv***ry trickle current is not present. A failure to respond to an open or close signal in a programmed time can be used to generate an alarm. VT Failure The VT failure feature monitors each phase of input voltage, generating an alarm and sending the programmed output signals when a failure is detected.

level monitoring elements and two rateof-change elements are available. When the measured quantity exceeds the pickup level, the relay can trigger an alarm or signal an output. Event Recording The relay captures and stores the last 256 events, recording the time, date, cause, and system parameters. Events may be recorded selectively by category, so that only events of interest are recorded. Oscillography A block of configurable volatile memory can be used for recording samples of the AC input voltages and current, and the status of logic inputs and output relays. This memory can be configured between the ranges of two to 16 blocks with 16 to 256 power frequency cycles of data respectively. The amount of pre-event data recorded is set by the user. Trace memory recording can be triggered by operation of selected features or logic inputs. Trip Counter The number of breaker trip operations is recorded, and can be displayed for statistical purposes (useful for units without operation counters). Metering The 750/760 performs accurate measure - ment of the following: • Actual V, A, Hz, W, Wh, var, varh, VA‑PF • Watthour cost • Phasor presentation of V and I • Symmetrical components of V and I The 750/760 saves up to 256 power frequency cycles of waveform data

The 750/760 is equipped with three standard serial communications ports, one RS232 located in the front panel, and two RS485/RS422 in the rear of the relay. A rear Ethernet port is also available as an optional feature. The front panel port allows easy local computer access. The rear ports provide remote communications or connection to a DCS, SCADA, or PLC. The baud rate of all the serial ports is variable from 300 to 19,200 bps. The optional Ethernet port can be used to connect the 750/760 to 10 Mbps Ethernet networks. The 750/760 supports ModBus® RTU, DNP3.0 Level 2, and ModBus® RTU TCP/IP protocols. The three serial ports support ModBus® RTU protocol, while any one of the two rear ports but not both can be configured to support DNP 3.0 Level 2. The optional Ethernet port supports ModBus® RTU via TCP/IP protocol. The communication system of the 750/760 is designed to allow simultaneous communication via all ports. Using Ethernet as the physical media to integrate the 750/760 to Local or Wide Area Networks, replaces a multidropwired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing monthly operating costs.
