The 745-W3-P5-G5-HI-ALR transformer protection system is a high-speed unit
The 745-W3-P5-G5-HI-ALR is a transformer management relay, part of GE Multilin’s 745 series, that protects and manages power transformers from small to large. The relay provides a range of functions 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 has a number of adaptive relay features, such as dynamic CT ratio mismatch correction, adaptive time overcurrent elements, and adaptive harmonic suppression. The 745-W3-P5-G5-HI-ALR is also capable of conducting simulations designed to test relay operation inferred from computer-generated waveform data. This data can then be digitized and downloaded for further use.
The 745-W3-P5-G5-HI-ALR’s 40-character backlit LCD display and input keyboard allow users to adjust Settings manually; The device also has an RS232 program port that makes it easy to connect computers running EnerVista 745 setup software for more convenient set point management. The Enervista 745 software serves as a single program for configuring, maintaining, troubleshooting, and monitoring the operation of relay functions. The front panel contains a number of leds that indicate the various states of the system during regular functions. The 745-W3-P5-G5-HI-ALR is packaged in the 745 SR series unit and provides mechanical protection during operation and also has a dust door. The relay provides sixteen logic inputs and eight output relays. This special transformer management relay in the 745 series provides three windings per phase and operates on a higher control power supply of 90 to 300 VDC; 70 to 265 VAC at 48 to 62 Hz. In addition, the 745-W3-P5-G5-HI-ALR includes analog input/output, life loss, and limited ground fault options.
