Inspection And Test Plan - Raytech mini-ATOS Instruction Manual

9 Inspection and Test Plan

In the lifetime of a high voltage asset, usually a measurement or group of measurements have to
be performed periodically and also sometimes occasionally. The aim is to inspect the health
condition or to detect the suspected failures. In mini-ATOS, each group of measurements is called
a Test Plan which forms an Inspection.
Figure 33 shows an example of a test plan for a 3-phase power transformer. It consists of a turns
ratio test, a winding resistance test and a demagnetization.
You can enable the edit mode (Figure 34) to adjust the order of measurements and add or remove
them by tapping the edit icon . You can touch and hold the move icon and try to change
the position of each measurement item.
In each measurement item, it can be seen that the measurement Settings and the number of the
tests performed from all the tests possible to perform are written. When you tap the measurement
settings button , the setting window will be opened from the right side. To find out which
settings are there for each measurement, please refer to chapter 10 and see each measurement
method settings.
By tapping the yellow right arrow, the measurement view will be opened and from there it is
possible to perform the test.
