About the 745-W3-P5-G5-HI-A-E

GE Multilin 745-W3-P5-G5-HI-A-E Transformer Protection System

Box content: SR469 Motor Management Relay; SR489 Generator Management Relay; SR735/737 Feeder Relay; SR745 Transformer Management Relay; SR750/760 Feeder Management Relay
High-Speed Protection System: The 745-W3-P5-G5-HI-A-E is a high-speed, draw-out transformer protection and management system from the General Electric Multilin 745 series.
Three-Winding Configuration: This particular model features three windings and includes analog inputs/outputs and an enhanced LCD.
High Control Power: It is the high control power version of the series.
Current Ratings: Its windings each function on a phase current input rating and ground current input of 5A.

Metering and Data Monitoring

Integrated Metering: The 745 employs advanced metering technology, which reduces the need for external equipment and connections to the transformer system.
Comprehensive Monitoring: It can monitor and record essential values such as voltage, current, power, energy, and temperature.
Data Access: These values can be displayed on the enhanced LCD or reviewed in detail using GE's EnerVista 745 program.
Connectivity Options: Computers can connect to the system via RS232 or RS422/RS485 ports. Models with Ethernet capabilities (indicated by a "T" in the model number) are also available for network connection.

Cost Reduction and Asset Monitoring

Asset Monitoring for Cost Savings: The relay reduces costs through asset monitoring, calculating hottest-spot temperature and aging factors to optimize replacement or maintenance schedules for power transformers.
Adaptive Capabilities: Its adaptive features further lower costs by reducing overall system strain and providing alerts for problems within the transformer.

Feature Options and Customization

Field-Addable Features: This relay does not inherently include the "loss of life" feature or the "restricted ground fault" feature, but both can be added in the field according to GE Multilin.

Frequently Asked Questions about 745-W3-P5-G5-HI-A-E

For the Transformer Protection System Multilin 745-W3-P5-G5-Hi-A-E, can this system dress the power requirements of different power systems?

The Multilin 745 systems, and in this case specifically the 745-W3-P5-G5-Hi-A-E transformer managment relay, are designed to handle the differing power requirements of various system configurations. There are unique setpoint groups so that the operator is able to choose which setting is appropriate for the differing protection requirements for a given power system configuration. The 745-W3-P5-G5-Hi-A-E has the option to select from up to four different groups of relay settings.

What phase current input rating does the 745-W3-P5-G5-Hi-A-E Multilin transformer management relay have?

The 745-W3-P5-G5-Hi-A-E Multilin transformer management relay has a phase current input rating that is designated by the P5 alphanumeric code within the part number. In other words, the winding 1, winding 2, and winding 3 are all equal to 5 A. If this code was P1, all the windings would be equal to 1 A, and for more diverse selections (P15), for example, the first winding is equal to 1 A and the second is equal to 5 A. The manual has more specific breakdowns for various P options.

What is the frequency for the transformers of the 745-W3-P5-G5-Hi-A-E Multilin transformer management relay?

The 745-W3-P5-G5-Hi-A-E Multilin transformer management relay is three winding with a frequency of 50 or 60 Hz nominally.
