About the 345-E-P1-G1-L-E-E-N-N-SN-D-N

General

The 345-EP1G1LEENNSNDN is a transformer protection relay from GE Multilin. This unit was designed to provide control, management, and monitoring of power transformers in addition to primary or backup protection. This series combines all these features into one unit and was created to be made-to-order when originally manufactured. As a result, this particular model carries many optional feature sets denoted by the part number.

Key Features

Some of the more notable optional features on the 345-EP1G1LEENNSNDN are the 1A ground and phase CTs, low-voltage power supply, and drawout case design. On these CTs, windings 1 and 2 are both 1 amp. The low-voltage power supply was made to provide 24-48 volts of DC power to the relay. The drawout case makes it easier to access the internal components of the relay than the non-drawout version of the case. This simplifies the installation process as well as wiring, maintenance, and testing.

More Features

The 345-EP1G1LEENNSNDN has many baseline feature sets present as well. For example, the communications, faceplate, and coating of this model use the most standard option available. The standard communications package includes a front USB and rear RS485 port. Supported protocols by this package include Modbus RTU, IEC60870-5-103, and DNP3.0. The standard faceplate includes an LCD with a full menu with actual values and setpoints as well as 10 inputs, 2 Form A outputs, and 5 Form C outputs. This unit lacks harsh environment conformal coating.
