Product description
The Multilin DGPR is a retrofit solution for the Digital Generator Protection (DGP) Relay. The
DGPR is a one-to-one replacement of a DGP relay and includes a G60 Generator Protection
System, which is part of the GE Universal Relay (UR) series of products.
The G60 is a microprocessor-based relay that measures generator conditions directly via
CT and VT inputs and via other sources of information, such as analog, communication,
and contact inputs. The G60 protects, controls, and monitors the operation of generators
driven by steam, gas, or hydraulic turbine.
One of the benefits of the DGPR is ease of wiring. Simply disconnect the wires from the
back of the DGP and connect them to the back of the DGPR.

The DGPR solution includes
•
G60 relay with redundant power supply
•
Five test switches for CT, VT, Trip, and DC circuit isolation on the front of the unit
•
Eight 14-pin terminal blocks at the back of the unit to replicate DGP terminals
The DGPR is pre-wired for all connections between the G60, test switches, and terminal
blocks.
