About the 745-W2-P1-G1-LO-E

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. 

The relay is able to function in a range of conditions, operating comfortably at temperatures ranging from -40°F to +140°F. The 745-W2-P1-G1-LO-E can also sustain humidity up to 90% non-condensing and altitudes of up to 2000m. Operating the relay in conditions outside of the recommended parameters will lead to system damage over time. An optional conformal coating (not included on this version of the model) can offer further protection against dust, humidity, harsh temperatures, and chemical corrosion. If desired, prospective buyers can select a unit in the series that features the conformal coating or can request AX Control adds it to this model before shipping.
