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

The quantities and measurements for differential protections are accessed via the
HMI paths provided below. The measurement outputs shown here include various
trip and start signals. The magnitude of the differential currents are shown here.

Transformer differential protection, two winding T2WPDIF

Main menu/Test/Function status/Differential protection/
TransDifferential2Wind(PDIF,87T)/T2WPDIF
Displays available instances of T2WPDIF with several measured values each. The
data available here ranges from the general common trip signal to the magnitude of
the bias current. The magnitude of the second and fifth harmonic differential
current for all phases, block signals and start signals make up the bulk of the data
presented in this view.
