Raytech TR–Mark III 250V - Transformer Information Entry; Entering Rated Voltage Data; Adding Identification Details; Setting General Parameters

Instruction Manual TR-Mark III 250V Version 1.10 Preliminary Page 36 of 57
8.4 Info
This screen has three goals:
 Helping the operator to identify Transformers
 Feeding TR-Mark III 250V 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. TR-Mark III
250V 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 above.
 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)
