Improper handling of the BA test equipment may lead to material damage.
•
Always unpack and store the BA test equipment according to the
instructions of this manual.
Improper handling of test vessels, oil and electrodes may lead to test sample
contamination and result in inaccurate test results.
•
Never touch the electrodes with bare fingers.
•
It is recommended to wear powder-free latex, nitrile surgical gloves or
equivalent when handling test vessels, oil and electrodes.
2.2 Appropriate Applications
The BA test instrument is designed to automatically test the breakdown strength
of liquid dielectrics.
Test Liquids
Insulating oils used in electrical apparatus such as transformers, tap changers,
circuit breakers, cables etc. are appropriate test liquids. Test liquids with boiling
points below 110 °C (230 °F) are not appropriate!
Test Methods
Test methods for determining the breakdown strength of liquid dielectrics are
specified by various international standards organizations. The appropriate
procedures, hardware and reporting requirements are specified in different
standards e.g. (IEC, VDE and ASTM, etc.)
The number of tests to be performed, voltage rise-rate, timing sequences, test
vessel and electrode configuration, test limits and ranges specified by certain
standards are pre-programmed in the BA test equipment. Refer to the section
“Technical Description” for a list of the automatic test standards applicable for
this BA instrument.
It is the responsibility of the BA instrument user to follow appropriate liquid
filling procedures and to set gap spacing of the electrodes according to the
selected standard.
