About the 345-E-P5-G5-H-E-S-N-N-3E-D-N
Introduction
The 345-EP5G5HESNN3EDN is a high-voltage transformer protection relay in GE Multilin's made-to-order 345 series. Units in this series are designed to provide management, control, and protection to power transformers. This protection may be primary or the 345-EP5G5HESNN3EDN may also serve as a backup protection device. This unit's primary strength is its communications, which uses the most advanced feature set available to the series.
Main Features
The 345-EP5G5HESNN3EDN's communications package includes features like Ethernet and IEC 61850 protocol support in addition to the standard front USB and RS485 port. Another advanced feature of this model is the drawout case design. This case design is helpful in expediting time-consuming processes like testing and maintenance. This helps improve efficiency and minimize system downtime. This unit has 5A three-phase current inputs as well as a 5A ground input.
Miscellaneous Features
The 345-EP5G5HESNN3EDN uses a high-voltage 110-230VAC/110-250VDC power supply. This model has the standard current protection package, which include critical features like percent differential protection, inrush/overexcitation inhibit, overcurrent elements, and more. The overcurrent elements of this model are phase/neutral/ground/negative time overcurrent and phase/neutral/ground/negative instantaneous overcurrent. This model does not have the optional harsh environment conformal coating feature.
