GE Multilin | Multilin 745-W2-P1-G1-Hi-T-H Transformer Protection System Three Phase Two Winding High Speed Management Relay for the Protection of Power Transformers
The working data are some data that are frequently changed and accessed during the operation of PLC. It is stored in RAM to meet the requirements of random access. In the working data memory of PLC, there is a storage area for storing logic devices such as input/output relays, auxiliary relays, timers, counters, etc. The state of these devices is determined by the initial setting and operation of the user program. As required, some data will be kept in its current state with backup battery in case of power failure. The storage area where data can be saved in case of power failure is called retention data area.
Since the system program and working data are not directly related to the user, the form and capacity of the memory listed in the PLC product sample or user manual refer to the user program memory. When the user memory provided by PLC is not enough, many PLCs also provide memory expansion function.

Frequently Asked Questions about SR745-W2-P1-G1-HI-E-H
What specifications apply to the ethernet for the 745-W2-P1-G1-Lo-E Multilin option?
Actually the E does not stand for Ethernet. The E indicates that the 745-W2-P1-G1-Lo-E Multilin includes the enhanced display option with the larger LCD. For a transformer protection system to come with the Ethernet the part number must indicate a T, as opposed to an E. In that case, the transformer management relay would have an ethernet with a 10Base-T RJ45 connector. The ethernet would be Version 2.0 / IEEE 802.3 and with a Modbus TCP/IP.
How does the 745-W2-P1-G1-Lo-E Multilin address false tripping during inrush?
The 745-W2-P1-G1-Lo-E Multilin has many adaptive features that make it a great transformer protection system with regard to protection and management of various size power transformers. It can monitor both individual and total harmonic distortion in one relay management system. Specific to your question, it addresses false tripping during inrush with adaptive harmonic restraint. It can also adjust the pickup setting of adaptive time overcurrent elements in the event that load currents need to be supplied with a content that is highly harmonic.
