845-E-P5-H5-G5-H-N-N-A-N-N-M-S-P-F-B-SE-N-N-B-4-0 Transformer protection relay
845-EP5H5G5HNNAANGSPFBSENNBN is GE Multilin’s transformer protection system. The relay is designed to protect, control and manage transformer systems in utility or industrial applications. This model is designed for use in 2-winding and 3-winding power and distribution transformer systems. Units in this series were originally manufactured to order, so this particular model has certain optional features indicated by the part number.
Salient feature
845-ep5h5g5hnnaangspfbsennbn has 5a three-phase and ground current input. This model uses a high voltage 110-250vdc / 110-230vac power supply. Some of the advanced features of this model include its voltage metering and protection and control functions. Advanced voltage metering and protection feature sets include voltage per Hertz and directional power relays. The control function set adds FlexLogic, circuit breaker failure and VT fuse failure functions to the basic control functions.
Standard function
Many of the optional feature sets on 845-ep5h5g5hnnaangspfbsennbn use the most basic packages. For example, functions such as communication, monitoring, and current protection provide basic functionality. For communication, this still means that the model has usb front, rs485 rear, and Ethernet ports. In addition, this basic package also supports iec60870-5-103, Modbus RTU, Modbus TCP, DNP3.0 and DNP TCP protocols. Basic monitoring features include useful functions such as circuit breaker coil monitoring, harmonics, trip counters and circuit breaker arcing. Basic current protection includes neutral line/phase/ground transient overcurrent and neutral line/phase/ground time overcurrent.
