The program assists in managing system setup and automatically flags programming errors or conflicts as the user adjusts setpoints.

The 745-W2-P1-G1-HI-T-H’s enhanced 40-character display is larger than the base model and includes an extended keypad for easy manual setpoint entry.

The enclosure is 9″ high by 7″ wide by 7 ⅛” deep. The transformer protection system can be mounted on a standard 19″ panel, but care should be taken that the enclosure door opens and closes freely without contact with other components.

A number of LEDs on the front of the chassis alert the user to various statuses and errors in real time.

Frequently Asked Questions about the 745-W2-P1-G1-HI-T-H

What makes the Multilin 745-W2-P1-G1-Hi-T-H unique compared to other transformer protection relays in the 745 series?

The 745-W2-P1-G1-Hi-T-H Multilin transformer protection series contains unique options that differ from other part numbers.

Notably, the “-H” option indicates that the relay has a harsh chemical environment conformal coating for operation in harsh environments.

The T option in the 745-W2-P1-G1-Hi-T-H Multilin Dual Winding Transformer Management Relay differs from other relays in the 745 system in terms of display and Ethernet.

Transformer protection systems without the T option have either a basic display (B) or an enhanced display (E) with a larger LCD.

The T option comes with an enhanced display, larger LCD, and 10Base-T Ethernet.

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

The 745 Multilin series is a series of transformer protection systems that have the ability to manage and protect power transformers.

For this reason they are known as transformer management relays. As with the other relays in the 745 series, the

745-W2-P1-G1-Hi-T-H is capable of using frequency, percentage difference, overcurrent and overexcitation protection elements as well as harmonic (single harmonic and total harmonic (THD)) tracking elements in one system.
