About the 745-W2-P1-G1-HI-R-E
The 745-W2-P1-G1-HI-R-E is a 745 Transformer Protection System. This unit was manufactured by General Electric to provide protection for small, medium, and large power transformers. The 745-W2-P1-G1-HI-R-E can be used as primary or back-up protection for these transformers.
There are several benefits to using the 745-W2-P1-G1-HI-R-E and the 745 system. This series has metering capabilities, along with a monitoring system. The metering function eliminates the needs for an external metering device. The monitoring system allows users to see the individual harmonics and total harmonic distortion.
The 745-W2-P1-G1-HI-R-E has several protection and control features. Some of these are:
- Phase and ground overcurrent elements
- Overexcitation protection
- Under/overfrequency protection
- Percent differential protection
The 745-W2-P1-G1-HI-R-E also works to extend the life expectancy of transformers.
