Description

The Multilin 745-W2-P5-G5-Hi-R-T Transformer Protection System has options as designated by the R and the T. The R indicates a restricted ground fault option. The restricted ground fault option for the 745-W2-P5-G5-Hi-R-T has two elements. It has a dropout level of 97 to 98 percent of pickup. The slope range in steps of 1 ranges from 0 to 100 percent. The pickup delay is listed in the manual at 0.00 to 600.00 s in steps of .01.
The T option is the highest option that may be selected for display and ethernet. The three options are either basic (B), enhanced display and a larger LCD (E), and finally an enhanced display, larger LCD, with an Ethernet (T). The 745-W2-P5-G5-Hi-R-T transformer protection system has the final option or the T option, which does include the larger LCD, and an ethernet. The display is enhanced when compared to the basic option. The ground current input rating is designated for the Multilin 745-W2-P5-G5-Hi-R-T by the G5 option within the part number. Historically there are four possabilities here: G1, G5, G15, G51. In this case, for the Multilin 745-W2-P5-G5-Hi-R-T, the G5 option includes a ground current input rating where winding 1/2 is equal to 5 A and winding 2/3 is equal to 5 A.
