Product Description

Unit Introduction

The 345-EP5G5HEMNN3EDH is an advanced model of transformer protection relay in the 345 series by GE Multilin. This model has many of the most advanced options available to the series selected. This unit was designed to provide control, protection, and management to industrial and utility power transformer systems. This unit may work in various applications such as providing primary protection or backup protection to autotransformers, two winding power transformers, distribution transformers, and reactors.

Advanced Features

The 345-EP5G5HEMNN3EDH has several advanced features, like its current protections, communications, case design, and environmental protection. The current protections of this model provide breaker failure and restricted ground fault in addition to the standard features. The communications package includes Ethernet and support for Modbus TCP/IP, DNP3.0, IEC 61850, and IEC 60870-5-104 protocols. The case design is drawout, which provides easier access to internal components and reduces total system downtime. This unit is coated in harsh environment conformal coating, which adds a layer of protection against dust, humidity, and other environmental hazards.

Other Features

The 345-EP5G5HEMNN3EDH has a high-voltage power supply. This power supply is rated for 110-250VDC or 110-230VAC. The ground current input and three-phase current inputs on this model are all rated for 5A. This unit has a front panel rated for ingress protection at an IP42 level.
