GENERAL ELECTRIC 745-W2-P5-G5-HI-A-L-R Transformer protection system

Transformer protection and management is a difficult task, but GE Multilin 745-W2-P5-G5-HI-A-L-R’s adaptive

features and system monitoring capabilities streamline the process with ease. Intended to work with transformer

systems small to large, the 745 is a highly configurable transformer protection relay. Features such as adaptive

harmonic restraint help maintain system security during inrush events. Users can also adjust how the relay interacts

with the system by adding, removing, or editing setpoints, which are configurable settings that determine how the relay

behaves. The 745’s FlexLogic™ technology increases versatility and decreases the need for auxiliary components

and wiring, allowing the configuration of unique equations that provide customized outputs in the system.
The 745-W2-P5-G5-HI-A-L-R’s display screen is enhanced over the base model and is larger as a result.

The screen is noticeably wider and the expanded keypad makes inputting and navigating the relay easier.

The back terminal of the 745-W2-P5-G5-HI-A-L-R contains a large number of ports to enable numerous and highly

configurable connections, including sixteen logic inputs. The rear terminal’s RS485/RS422 ports is intended for systems using multiple

relays and can easily connect computers running the relay’s EnerVista 745 computer software program; alternatively, computers

running EnerVista can connect through the RS232 port on the front of the device for single relay monitoring.
