Metering & Monitoring

Overview

The 825-P relay includes metering functions to display the present values of

current, voltage (if included), and RTD measurements (from the external 825-

PR12D Module). The relay provides the following methods to read the present

meter values:

• R

otating front panel display

• Fr

ont panel menu

• F

ront panel EIA-232 serial port

• N

etwork port (if installed)

• An

alog output

For monitoring and preventive maintenance purposes, the 825-P provides a

mot

or operating statistics report, available using either the front panel, the serial

port, or the optional network port.

Metering

The 825-P meter data falls into the following categories:

• I

nstantaneous metering

• Th

ermal metering

– Th

ermal model metering

– RT

D metering

Note that the phases and neutral are identified by 1, 2, 3, N for currents and A, B,

N for voltages.

Table 46 details each of the meter data types in the 825-P. Chapter 3: Front Panel

Operation and Chapter 5: Using MPS Explorer describe how to access the

various types of meter data using the relay front-panel and communications ports.
