About the 845-EP5H5G5HSNAAFGSPFA3ACNAN
Summary
The 845-EP5H5G5HSNAAFGSPFA3ACNAN is an 845 series transformer protection relay from GE Multilin. This model comes equipped with several advanced optional features that put this model several steps above the baseline for units in this series. These optional features are denoted in the model name, with more information about these features being available in the naming guide found in the "Manuals" section of this page.
Notable Features
The 845-EP5H5G5HSNAAFGSPFA3ACNAN has advanced features in most major functions. These functions include voltage metering and protection, monitoring, communications, security, and control. Some features included in these advanced packages are things like directional power relay, harmonic detection, IEC 61850 protocol, CyberSentry Level 1 security, and VT fuse fail. This model has a basic current protection feature set and lacks wireless communication capability. This basic current protection still offers critical functionality in areas like setpoint group control and virtual inputs. This unit does have an RJ45 copper 10/100M advanced communications connector.
Other Features
The 845-EP5H5G5HSNAAFGSPFA3ACNAN has series-standard features that also give this model important functionalities. As an example, this unit has harmonic inrush/overexcitation inhibition features which help to deal with the current inrush that comes during energization of the transformer. Another example is the restrained and unrestrained differential protection that is present in this unit.
