Product Description

Whether using the 745-W2-P5-G5-HI-A-E as a primary device or as an emergency back-up relay, GE Multilin’s 745 is an excellent choice for your transformer management and protection needs. This multi-processor relay adjusts to your systems fluctuations, employing technology such as adaptive harmonic restraint and adaptive time overcurrent elements to react to variable changes in real time. The 745’s metering capabilities can record variables such as temperature, current demand, frequency, total harmonic distortion, and more. That data can then be trended and exported in EnerVista 745, the relay’s software component. These capabilities both streamline the user experience and reduce costs by eliminating the need for excessive auxiliary equipment or metering devices.

745-W2-P5-G1-HI-E GE two-winding transformer management relay

This model works best with a higher control power system, able to handle 90 to 300 volts direct current and 70 to 265 volts alternating current; this contrasts with the low control power editions of the model, which run at 20 to 60 volts direct current and 20 to 48 volts alternating current. This difference is demarcated in the model number by the phrase “HI”. Users should purchase the appropriate control power level for their transformer system, as voltage inputs outside of the power range can cause system damage over time.

The 745 also sees heightened security implementations, adding the option of creating a numeric passcode to prevent unsanctioned setpoint changes. After a passcode is incorrectly entered three times, the 745-W3-P5-G5-HI-R-E is able to generate a minor self-test error, alerting users to the situation at hand. The passcode can be assigned, enabled, and disabled easily through the 745’s setpoint system by authorized users.

Frequently Asked Questions about 745-W2-P5-G5-HI-A-E
