5.1 Test Description
The DTS60A dielectric oil tester supports the execution of user
programmable testing scenarios. The main objective of the programmable
test is the control of the high voltage on a time basis. Moreover, the test
includes options for controlling the Stirrer and the Breakdown
measurements. In this paragraph, a detailed description of the test program
structure, as well as the test operations are presented.
5.1.1 Test Structure
The Test consists of an Information Session, a Startup Session,
and a Main Session.
The Information Session contains general details for the test. These are
the following:
a. Program Name (up to 12 characters)
b. Electrodes Spacing (mm/in)
c. Number of Stages (see Main Session)
d. Creation Date/Time
The Startup Session refers to the start-up time. This is the period after the
starting of the test (after pressing the ENTER key) until the system enables
the output voltage to the oil-sample. The parameters included in the Starup
Session define the Wait Time (SWT) after the start of the test and the part
of this time (or all this time) the enable or disable of the stirrer. The Startup
Session includes the following programmable parameters:
a. Startup Wait Timer (sec) - SWT
b. Startup Stirrer Timer (sec) -SST
The Main Session consists of a series of a maximum of 30 Stages. Every
stage includes a set of programmable parameters:
a. Voltage Type (kV or kV/sec)
Two are the possible voltage types. If a rated increase/ decrease is
desired, the type refers to kV/s. If a stable voltage is desired, the type
refers to kV.
b. Voltage Value (kV) or Voltage Rate (kV/s)
c. Stage Duration (sec)
d. Stirrer Timer (sec) - ST
This timer starts counting from the beginning of the current stage and
enables the stirrer for the programmed time.
e. After Breakdown Wait Timer (sec) -ABDWT
