1.4 Setup the Equipment

The setup of this equipment has been minimized by careful
consideration of the operator during design. The DTS-60xx one-piece
construction permits convenient portability. The DTS-60xx test set
requires that the unit is operated with the control panel in the
horizontal position, to keep oil level over high voltage transformer in
the high voltage tank.

1. Select a location for the unit that will allow easy
viewing of the User Interface

2. Be sure that all the controls are off, in their de­energized state.

3. Remove all components and oil vessels from the test
chamber

4. Install the input line cord into the Input Power
receptacle

5. Connect the line cord to a suitable (120V or 230V,
see Specifications Table) grounded power source.

6. Select the desired Test cell. Fill in with sufficient
insulating liquid for the testing to be performed.

7. Clean the Test Cell and Electrodes thoroughly and
adjust the electrodes to conform with the proper ASTM
Specification. Be sure the electrodes are securely
tightened on the adjustment posts inside the oil vessel.

Use Isolation transformer (1/1) if the
electrical installation has neutral
earthing.

All the oil vessels designed and made by High

Voltage Inc.
have interchangeable posts and electrodes. These
oil
vessels were designed to conform to the ASTM test

14

DTS-60A OPERATORS MANUAL

specifications requiring simple disassembly for
cleaning.
This design greatly reduces the time and effort
required
keeping your oil vessels in top operating condition.

The operator of this equipment must

use good judgement and follow all
safety precautions noted in this guide
to ensure the protection of himself and
others in close proximity to the test
area. Failure to follow the instruction
could result in injury or death.

3.1 Simple Test Operations

This section describes the Simple Test operation. The Simple Test
generates an (adjustable rate) high voltage ramp until a breakdown
happens. The user may repeat the procedure for one insulator-oil filling and
that will be considered as a single test. The possible settings are the rate of
rise for the voltage and the stirrer control. At the end of the test the system
will prompt the user for a printout and the test results will be stored in the
History structure (see paragraph xxx).

The flowchart in figure 3-1 depicts the operations of the Simple Test.

The DTS60A includes most of the international standards for testing
insulating oil. Upon selecting such a test from the menu, it is
automatically executed without any further interaction. When the test is
finished, the system prompts the user for a printout of the results and the
results are stored in the history memory.

All the test are based on a specific pattern of procedures:

1. Verification of electrode spacing and electrode type

2. After first filling inactivity time period - SWT

3. After first filling stirrer enable time period - SST

4. Iteratively run of test stages

1. Predefined increase of voltage

2. Breaddown detection

3. After Breakdown inactivity time period - ABDWT

4. After Breakdown stirrer enable time period – ABDST

5. After Breakdown Stage - ABDSTG

6. Discard/ Not Discard stage breakdown voltage -

The available standards are the following:

1. IEC 156/95 - International

2. IEC 156/63 - International

3. ASTM D1816/84 - USA

4. ASTM D877/87 - USA

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

49

DTS-60A OPERATORS MANUAL

After a breakdown occurs, the system will idle for this programmable

duration.
f. After Breakdown Stirrer Timer (sec) -ABDST

After a breakdown occurs, the system will enable the stirrer for this

programmable duration.
g. After Breakdown Stage (0…29, next, end) - ABDSTG

After the above timers the test will proceed to another stage. This

programmable parameter indicates the next stage. The value can be

any following stage (eg. If current stage is 10 then the value could be

11 to 29), next if it is desired to continue to the next stage, or end if

it is desired to stop the test.
h. Store Breakdown Voltage (yes/no)

If the user selects the yes option, the detected breakdown voltage will

be calculated to the statistics. Otherwise, the detected breakdown

voltage will NOT be calculated into the statistics.

In the following paragraph there is a detailed description of the Test
Program Operation, thus the reader will understand the exact meaning of
the above parameters.

DTS-60A OPERATORS MANUAL

5.1.2 Test Operations

Every Test operates according to the programmable parameters of the
above sessions. This paragraph will describe the operations of the system in
respect with the programmable parameters.

During Startup the system initializes the Startup Wait Timer - SWT
and the Startup Stirrer Timer - SST. The system introduces an idle
operation time according the 1
filling period’. During this time the system could turn on the stirrer according

The Test continues the operation according to the parameters described
in the 1
voltage controller, which will control the high voltage output. More
specifically, if the voltage value indicates kV then the voltage controller will
immediately adjust (according to the maximum system’s rate) the output
voltage to the programmed value therefore keeping the voltage stable for
the specified Duration Parameter. If the voltage value indicates kV/sec then
the voltage controller will adjust the output voltage according to the desired
rate for the specified duration. It is noted that the Duration Parameter could
take the value “Breakdown” which means no specified duration.

an alternative method is supported. The method is based on Script
Test Program Files, that the user could develop using an editor on a
Personal Computer (PC). The following paragraphs explain the
commands and arguments of the specific script files. Furthermore two
examples are presented. The Script Test Files downloading to the
equipment is described in chapter 8 (Remote Operation).

5.4.2 Script File Test Examples

In order to make clear the above descriptions two examples will be
mentioned. The first one concerns the IEC 156/63 International Standard
and the other a more complicated scenario.

a. IEC 156/63 International Standard

The IEC_156/63 Standard is a 6 Stages program. Every stage is
independent, which means that it is desired that every stage will have a
breakdown. After filling the oil sample it is required to wait for 10 minutes.
Every stage voltage will start from zero until breakdown, with a voltage
increase rate of 2kV/s. After every breakdown, the test will store the output
voltage (breakdown voltage) and then it is desired to wait for 5 minutes with
the stirrer enabled for 1 minute. After every breakdown the test will proceed
to the next stage. Finally, it is required for the system to print a results
report.

The IEC 156/63 Standard should be described in a Script Test File as follows:

Script File 1 – IEC_156/63 Standard

It is possible to replicate the whole test, in order to make a more
complex scenario. For example, a 4 replicated test scenario could be a Test
with 28 stages. In such a test the user should edit the After Breakdown
Stage parameter, in order for the operation to proceed with the first stage of
the next replica. It is noted that after a breakdown 10 min idle time will be
programmed and all this time the stirrer will be enabled.
