About the 745-W2-P5-G5-HI-L-E
The 745-W2-P5-G5-HI-L-E is from the 745 Transformer Protection System. This series was designed by GE Multilin for protection of small, medium, and large power transformers. The 745-W2-P5-G5-HI-L-E has a variety of protective features, including overcurrent, overexcitation, and over/underfrequency protection.
The 745-W2-P5-G5-HI-L-E has two windings per phase, with both windings having a 5A phase current input rating. The 745-W2-P5-G5-HI-L-E also has several communications options, including RS232, RS485, and RS422 ports. This relay is equipped with EnerVista Software which helps with commissioning and configuration of the relay. This is a highly sophisticated software.
This relay also has a simulation mode, which allows users to test the functionality of the relay before using it with a transformer. The 745-W2-P5-G5-HI-L-E can use either computer generated data or preexisting data.
The 745-W2-P5-G5-HI-L-E can be used as primary and back-up protection for transformers. More information about the 745-W2-P5-G5-HI-L-E can be found in the online documentation that can be found under our "Manuals" tab. These documents have been provided by GE to assist 745 System operators. There is a data sheet for the 745 systems, as well as a more comprehensive manual.
