About the 745-W2-P1-G1-HI-T-H

GE Multilin 745-W2-P1-G1-HI-T-H Transformer Protection Relay

  • Optimized Transformer Management: This relay is designed to extend transformer life expectancy and optimize transformer performance for small, medium, and large systems.
  • Key Protection Features: It includes features like transformer overload protection and overexcitation protection to ensure smooth operation.
  • Comprehensive Monitoring: The device can monitor, record, and trend system variables such as temperature, voltage, power, energy consumption, and frequency rate-of-change. These values are easily referenced using the EnerVista 745 software.

EnerVista 745 Software & Connectivity

  • Setpoint Editing: The EnerVista 745 software allows for easy editing of setpoints.
  • Flexible Connectivity: Connecting the relay to a computer is simple with GE Multilin's Quick Connect feature, supporting connections via Ethernet, the front-facing RS232 port, or the rear RS485/RS422 ports.
  • Programming Assistance: The software helps manage system settings and automatically flags programming errors or conflicts during setpoint adjustments.

Physical Design & Installation

  • Enhanced Display: Features an enhanced 40-character display that's larger than the base model, along with an expanded keypad for easier manual setpoint entry.
  • Dimensions: The case measures 9" in height, 7" in width, and 7 ⅛" in depth.
  • Mounting: It can be mounted on a standard 19" panel. Ensure the chassis door has clearance to open and close freely without obstruction from other components.
  • Real-time Status Indicators: The front of the case includes LEDs that provide real-time alerts for various statuses and errors.

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
