This product is under last-time buy. Orders may be placed until sr7750 Decemberand will be fulfilled based upon availability. As an alternative, please refer to the relay. This easy to use relay provides comprehensive protection functions for feeders and back up protection for bus, transformers and transmission lines at a reduced product life cycle cost.

Convenient COMTRADE and Sequence of Events viewers are an integral part of the Setup software included with every relay, to carry out postmortem event analysis to ensure proper protection system operation.

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.

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 supervisory 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. The VT failure feature monitors each phase of input voltage, generating an alarm and ssr750 the programmed output signals when a failure is detected.

Any external quantity may be monitored via an auxiliary current input. Two analog input level monitoring elements and two rate-of-change elements are available. When the measured quantity exceeds the pickup level, the relay can trigger an alarm or signal an output.

The relay captures and stores the last events, recording the time, date, cause, and system parameters.

Events may be recorded selectively by category, so that only events of interest are recorded. 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 gs of two to 16 blocks with 16 to 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. The number of breaker trip operations is recorded, and can be displayed for statistical purposes useful for units without operation counters.

A rear Ethernet port is sr7750 available as an optional feature. The front panel port allows easy local computer access. The baud rate of all the serial ports is variable from to 19, bps. A 40 character display allows access to setpoints, actual values, and diagnostic messages generated by a trip or alarm condition.

The can display 30 user-selected messages during keypad inactivity. Traditionally, retrofitting an existing relay has been a challenging, time consuming task often requiring re-engineering, new drawings, panel modifications, re-wiring and re-testing. With the new 8 Series Retrofit Kit users are able to install the Feeder Management System without modifying existing cutouts and wiring, and without any drawing changes or re-engineering time.

EnerVista 8 Series Setup Software provides automated setting file conversion. Once completed, a graphical report is provided to verify and call out any specific settings that may need attention. Simply remove the terminal blocks and then remove the SR chassis from the panel.

No need to disconnect any of the field wiring. Insert the new 8 Series Retrofit chassis into the switchgear and simply plug-in the old terminal blocks – there is no need to make any cut-out modifications or push and pull cables. Fault Locator The relay uses captured data to calculate the type, distance to and the impedance of the fault. Breaker Conditions The relay calculates the per-phase wear on the breaker contacts to establish a threshold.
