EATON Instructions for the FP-5000

The Eaton FP-5000 Protective Relay is a multifunction panel

mounted, microprocessor-based relay, designed for both ANSI

and IEC applications (Figure 1). It is a self-contained device which

operates from either ac or dc control power and provides true

rms sensing of each phase and ground current. Only one relay is

required per 3-phase circuit. Current, voltage and operator

selectable protective functions are integral to each device.The FP

5000 is designed to protect the mains, ties or feeders at any

voltage level. It is primarily applied on medium voltage

distribution circuits up to 69 kV. The FP-5000 monitors several

primary and derived electrical parameters of the system.

1.2  Audience

The audience for this document is the Specifying or System

Engineer, the operating personnel and the troubleshooting

personnel. This document will guide the system user to apply

and program the FP-5000. The document will provide operating

information, enabling the operating user to start and trip the

breaker associated with the FP-5000. The operator can refer to

this publication regarding any operation of the FP-5000. This

document will also provide information to program the FP-5000

and use the troubleshooting features to collect and analyze

historical, trending and oscillographic data.

1.3  Safety and Caution Notices/Disclaimers

This technical document is intended to cover most aspects

associated with the installation, application, operation and

maintenance of the Eaton FP-5000 Protective Relay. It is provided

as a guide for authorized and qualified personnel only in the

selection and application of the FP-5000 Protective Relay. Please

refer to the specific WARNINGS and CAUTIONS that follow

before proceeding. If further information is required by the

purchaser regarding a particular installation, application or

maintenance activity, a Eaton representative should be

contacted. Technical Support is available 24 hours a day by

phoning Eaton Power Management Applications Support at 1

1.6  FP-5000 Hardware Resources and Description

The FP-5000 has four current measuring inputs, four voltage

measuring inputs, eight contact inputs, seven contact output

relays, communications and a front panel user interface.

Based upon the firmware loaded into the flash memory of the

FP-5000 and the customer settings entered manually through the

front panel or through the RS-232 port using the PowerPort

program, the microprocessor observes inputs, sets outputs and

stores data for user retrieval
