GE 345-E-P5-G5-H-E-S-N-N-3E-D-N High voltage transformer protection relay
345-E-P5-G5-H-E-S-N-N-3E-D-N is a high voltage transformer protection relay in the GE Multilin custom 345 series. The units in this series are designed to provide management, control and protection for power transformers. This protection can be either primary or 345-E-P5-G5-H-E-S-N-N-3E-D-N can also be used as a backup protection device. The main advantage of the device is its communication, which uses the most advanced feature set available in the series.
Main feature
In addition to the standard front-facing USB and RS485 ports, the 345-E-P5-G5-H-E-S-N-N-3E-D-N communication package also includes Ethernet and IEC 61850 protocol support. Another advanced feature of this model is the draw-out housing design. This case design helps speed up time-consuming processes such as testing and maintenance. This helps improve efficiency and minimizes system downtime. The device has 5A three-phase current input and 5A ground input.
Other functions
345-E-P5-G5-H-E-S-N-N-3E-D-N uses high voltage 110-230VAC/110-250VDC power supply. This model has a standard current protection package, which includes key features such as percentile protection, surge/overdrive suppression, and overcurrent elements. The overcurrent elements of this model are phase/neutral line/ground/negative time overcurrent and phase/neutral line/ground/negative instantaneous overcurrent. This model does not have an optional harsh environment tri-paint feature.
