SR745-W2-P1-G1-HI-A-L-R-E transformer protection relay uses functions such as transformer overload protection and overexcitation protection to make the transformer run smoothly. It can also monitor, record, and predict system variables such as temperature, voltage, power, energy consumption, and rate of frequency change.

What makes the Multilin SR745-W2-P1-G1-HI-A-L-R-E unique compared to other transformer protection relays in the 745 series?

The SR745-W2-P1-G1-HI-A-L-R-E Multilin transformer protection series includes unique options for other device numbers. It is worth noting that the -H option indicates that the relay has a harsh chemical environmental conformal coating in order to work in harsh environments. The T option in the SR745-W2-P1-G1-HI-A-L-R-E Multilin double-winding transformer management relay is unique to other relays in the 745 system in terms of display and Ethernet. Transformer protection systems without the T option either have a basic display (B) or an enhanced display with a larger LCD (E). However, the T option comes with an enhanced display, larger LCD, and 10Base-T Ethernet.

SR745-W2-P1-G1-HI-A-L-R-E Multilin How do I monitor and manage power transformers?

The 745 Multilin series is a series of transformer protection systems designed to manage and protect power transformers. For this reason, they are called transformer management relays. The SR745-W2-P1-G1-HI-A-L-R-E series, like other relays, is capable of using frequency, differential percentage, overcurrent and overexcitation protection elements in one system and tracking harmonics (single and total harmonics (THD)).
