【英文介绍】

The 745-W3-P5-G5-HI-ALR is a transformer management relay that is part of GE Multilin's 745 series for the protection and management of power transformers from small to large. The relay provides a range of functions in a single device, including frequency, percentage 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 constraints. The 745-W3-P5-G5-HI-ALR is also capable of 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 acts 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 daily operation. The 745-W3-P5-G5-HI-ALR is configured in the 745 SR series to provide mechanical protection during operation and has a dust door. The relay provides 16 logic inputs and 8 output relays. This special transformer management relay in the 745 series offers three windings per phase and can operate at higher control powers, 90 to 300 VDC; 70 to 265 VAC, 48 to 62 Hz. In addition, the 745-W3-P5-G5-HI-ALR includes analog input/output, life loss, and limited ground fault options.
