Product Description

Able to extend transformer life expectancy and optimize transformer performance, the 745-W2-P1-G1-HI-T-H is a GE Multilin Transformer Protection Relay that protects and manages transformer systems small, medium, and large. Part of the 745 series, the 745-W2-P1-G1-HI-T-H employs features such as transformer overload protection and overexcitation protection to keep transformers running smoothly. It also has the ability to monitor, record, and trend system variables such as temperature, voltage, power, energy consumption, and frequency rate-of-change. These values can be quickly referenced using the relay’s software program, Enervista 745. 

The Enervista 745 software program can also be used to edit setpoints. Connecting the relay to a computer is easy with GE Multilin’s Quick Connect feature, and connection can be established through Ethernet, the front facing RS232 port, or the RS485/RS422 ports located on the back of the panel. The program heavily assists in managing system settings and is able to automatically flag when programming errors or conflicts are made by users adjusting setpoints.

The 745-W2-P1-G1-HI-T-H’s enhanced 40 character display is larger than the base model and includes an expanded keypad for easier manual entry of setpoints. The case has a height of 9”, width of 7”, and a depth of 7 ⅛”. The transformer protection system can be mounted on a standard 19” panel, and care should be taken that the door to the chassis can freely open and shut without making contact with other components. The front of the case has a number of LEDs that alert users to various statuses and errors in real time.

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

What is unique about the Multilin 745-W2-P1-G1-Hi-T-H compared to the other transformer protection relays within the 745 series?
The 745-W2-P1-G1-Hi-T-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-T-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-T-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-T-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-T-H Multilin have two or three windings per phase?
745-W2-P1-G1-Hi-T-H Multilin transformer protection systems have two windings per phase as indicated by the W2 option in the part number. 

Reviews For 745-W2-P1-G1-HI-T-H

Internal Review
(5.0)

The 745-W2-P1-G1-HI-T-H’s conformal coating adds a protective layer that shields the relay from moisture, chemicals, dust, and extreme temperatures: this makes it an excellent choice for harsh environments. -AX Control Tech Team
