GE Multilin 745-W2-P1-G1-HI-E-H

The 745-W2-P1-G1-HI-E-H Multilin transformer protection series contains unique options to other part numbers. Of note, the -H option indicates that this relay has a harsh chemical environmental conformal coating in order to function within a harsh environment. The T option within the 745-W2-P1-G1-HI-E-H Multilin two winding transformer management relay is unique to other relays in the 745 system in regard to its display and ethernet. Transformer protection systems that do not come with the T option either have a basic display (B) or an enhanced display with a larger LCD (E). The T option however comes with an enhanced display, a larger LCD, and an Ethernet that is 10Base-T.

How does the 745-W2-P1-G1-HI-E-H Multilin monitor and manage power transformers?

The 745 Multilin series is a series of transformer protection systems that function to both manage and protect power transformers. Thus they are referred to as transformer management relays. The 745-W2-P1-G1-HI-E-H, like other relays in the 745 series, is able to use elements of frequency, percent differential, overcurrent, and overexcitation protection elements with the tracking of harmonics (both individual and total (THD)) in one system. 

Does the 745-W2-P1-G1-HI-E-H Multilin have two or three windings per phase?

745-W2-P1-G1-HI-E-H Multilin transformer protection systems have two windings per phase as indicated by the W2 option in the part number.
