7 Transformer, Measurement and Data Structure
7.1 Introduction
There are thousands of instruments on earth that do a measurement and offer the possibility
to store a measured value. This is a very useful feature which saves a lot of time and
eliminates errors of writing down values by the operator. But still you have to do the handling
and organization of the measured data on your own. This may introduce one day mistakes
into your data set, especially when several measurements will be taken at once and sorted
after words, or, if several operators use the same storage device.
7.2 How it works
With TR-Mark III 250V we offer another powerful tool that increases comfort in handling
many transformers which are tested time after time. You do not have to sort a stored
measurement anywhere. Once a transformer, or let us say a transformer profile is created,
several measurements directly can be attached to it.
The profile or transformer contains the general (header) data. An attached result contains the
measurement of all transformer phases. Or to define it more exactly:
A transformer / profile contains:
Number of winding systems
Type of winding systems
Test voltage
Rated voltages (primary, secondary, tertiary)
Name plate info (name, serial number, location, manufacturer, type and remarks)
Max. ratio deviation and standard (ANSI, IEC, Australian)
A measurement contains
Measured results of all phases (ratio, deviation, current, phase angle)
Date and time of all measurements
What you usually will do is creating a new transformer (profile), do a measurement and store
it. In this case the profile and the actual measurement will be stored.
Or you load an existing transformer, do a measurement and store it. In this case, the new
measurement will be attached or let us say stored with the loaded transformer.
Please find this illustrated on the following page.
NOTE
There is no difference between saving a transformer or attaching the
actual measurement. Both are done with the button ‘save’ in the Main
screen. See chapter ‘8.1.2.3
