Funcrional Description
The 745-W3-P5-G5-HI-A-L-R-E-H is a transformer management relay and part of GE Multilin’s 745 series, protecting and
managing power transformers ranging from small to large. The relay offers an array of features in a single device,
including frequency, percent differential, overcurrent, and overexcitation protection elements. It is also capable of monitoring
individual harmonics and total harmonic distortion. The 745 boasts a number of adaptive relaying capabilities, such as dynamic
CT ratio mismatch correction, adaptive time overcurrent elements, and adaptive harmonic restraint. The 745-W3-P5-G5-HI-A-L-R-E-H is
also capable of conducting simulations intended to test relay operations extrapolated from computer-generated
waveform data. This data can then be digitized and downloaded for further use.
The 745-W3-P5-G5-HI-A-L-R-E-H’s 40 character backlit liquid crystal display and input keypad allow users to manually
adjust setpoints; the device also features an RS232 program port to easily connect computers running the EnerVista
745 Setup Software for more convenient setpoint management. The Enervista 745 software acts as a single program
from which to configure, maintain, troubleshoot, and monitor the operation of relay functions. The front panel
contains a number of LEDs that indicate various statuses of the system during routine function. The
745-W3-P5-G5-HI-A-L-R-E-H is encased in a 745 SR-series arrangement, which provides mechanical protection during
operations and also features a dust-tight door. The relay provides sixteen logic inputs and eight output relays.

Frequently Asked Questions About 745-W3-P5-G5-HI-A-L-R-E-H
| What differentiates the 745-W3-P5-G5-HI-A-L-R-E-H Multilin transformer protection system from other order codes found in the part number breakdown? |
|
The 745-W3-P5-G5-HI-A-L-R-E-H transformer protection system is unique to other options in that the W3 order code signifies three windings per phase in contrast to other parts with two per phase. Additionally, The P5 option indicates that each winding is 5 A for phase current input ratings. This part also has a high control power that is 90 to 300 volts DC, or 70 to 265 Volts AC with a range from 48 to 62 Hz |
| What is the purpose of the 745-W3-P5-G5-HI-A-L-R-E-H Multilin transformer protection system? |
|
The 745-W3-P5-G5-HI-A-L-R-E-H Multilin transformer protection system is based with a multi-processor model that is high speed and either is three or two winding (in this case the 745-W3-P5-G5-HI-A-L-R-E-H is three winding indicated by the W3 portion of the part number). The 745-W3-P5-G5-HI-A-L-R-E-H is a transformer managmenet relay designed to protect transformers that are small, medium, or large. |
| What are the ideal storage conditions for the 745-W3-P5-G5-HI-A-L-R-E-H? |
|
The manufacturer recommends a storage temperature between -40°C (-40°F) and 80°C (176°F). |
| Which communication protocols are supported by the 745-W3-P5-G5-HI-A-L-R-E-H? |
| The 745-W3-P5-G5-HI-A-L-R-E-H supports multiple communication protocols, including Modbus, DNP3, and IEC 61850, making it compatible with modern SCADA systems for remote monitoring and control. |
