GE SR745-W2-P1-G1-HI-E-H 745 Transformer Protection System

The GE SR745-W2-P1-G1-HI-E-H Transformer Protection System is a full-featured, high-performance transformer protection system designed to ensure stable operation and increase the service life of transformers. However, specific installation, operation and maintenance requirements, as well as compatibility with other equipment, may require reference to more detailed technical documentation or consultation with a professional engineer. Meanwhile, considering the complexity and diversity of electrical equipment, it is recommended to fully understand and test the system before use to ensure its safety and reliability.

Product Description

The highly configurable 745-W2-P1-G1-LO-E is a Transformer Protection System designed by General Electric Multilin and part of their 745 series. The relay’s FlexLogic™ technology can be used in tandem with its setpoint capabilities to create a versatile programming structure specific to the particular system’s needs. The 745-W2-P1-G1-LO-E’s more general transformer management features include underfrequency and overfrequency protection, transformer overload protection, CT correction factors, and more.

The device is encased in an 745 SR Series chassis which protects the relay during drawout operations and discourages dust from entering and damaging the relay. The chassis features a glass front so that users can monitor the various LEDs located on the front panel of the relay, which are able to indicate different system statuses and also alert users when errors arise. The LEDs can be green, amber, or a solid red depending on the corresponding status, providing an easy reference point for system health.
