8.3 Info
This screen has three goals:
Helping the operator to identify Transformers
Feeding TR-MARK III firmware with information, to improve its output.
Viewing and printing of results
and it contains four sections. The sections are chosen by touching their name on the left side
of the screen.
Rated voltage:
Here primary and secondary, and if
available tertiary voltage can be entered.
MARK-III automatically calculates voltage
and turn ratio based on these entries.
Voltages on Tap changers can be defined
manually or automatically by a wizard.
See picture beside.
Push into the field.
Add Info:
This section especially helps to identify a
transformer. Data like transformer name,
serial number, manufacturer, type and so on
can be entered and displayed.
General:
Maximal Ratio Deviation can be set in this
chapter. By default it is 0.5%. That means, if
the measured ratio deviates more than 0.5%
from the theoretical value, the measurement
will be designated as “failed”.
Here you can also define which transformer
standard is used. (IEC, ANSI, Australian)
