Function status

Overview

In the Function status section of the Test menu, data useful to the user in Test mode
can be found. The information available here is not limited to test applications
alone and provides information about the system as a whole.

Differential protection

High impedance differential protection HZPDIF

Main menu/Test/Function status/Differential protection/
HighImpDifferential(PDIF,87)/HZD
Displays available instances of HZPDIF with some measurements per instance.
These are the trip signal, the alarm signal and the measured RMS voltage on the
secondary side of the CT.

Current protection

Viewable data under Current protection consists mainly of trip status data under the
various categories of current protection which include overcurrent protection,
thermal overload, stub protection, pole discordance and variations of these.

Breaker failure protection CCRBRF

Main menu/Test/Function status/Current protection/BreakerFailure(RBRF,
50BF)/BFP
Displays an application dependent number of instances of CCRBRF with some
measurements per instance. The measurement outputs include trip status and faulty
circuit breaker alarm.
