Insulating fl uids are a key component of much electrical

equipment. Highly refi ned mineral oils, silicone fl uids, vegetable

oil (natural esters) and synthetic esters guarantee the operation

of transformers, medical and safety or even radar technology

devices. Insulating materials lose their insulating and cooling

properties due to impurities and ageing. The consequences

include damage and failures of equipment and systems, even

catastrophic failures resulting in transformer fi res and the

consequent costs and environmental damage.

The testing of insulating fl uids is therefore legally stipulated and

regulated through national and international standards. Equally

important are the economic reasons for regular testing to

include extended lifetime of equipment and optimal use of

insulanting oils to achieve enormous potential savings.

A good investment to avoid high costs.Insulating fl uids testing with BAUR.

BAUR oil testers are characterised by quality recognised

worldwide. Quality in the defi nition of BAUR and its customers

are not empty words. It is determined by criteria which have a

direct or indirect impact:

• Precision, reliability and scope of measuring results

• Reduction of testing time and costs

• High degree of individualisation and user friendliness

• Long lifetime of instruments

With these principles, BAUR makes complex technologies and

complex standards easy, safe and profi table for the customer.

Maximum quality, reliability and precision for

the safety and profi tability of your facilities.

• The extremely effi cient laboratory instrument BAUR

DTA 100 C for continuous operation and the mobile tester

BAUR DPA 75 C are used for breakdown voltage tests and

subsequently to determine the degree of impurity due to

external particles and water.

• The unique laboratory device worldwide BAUR DTL C, is

used to determine the dissipation factor tan δ, the specifi c

resistance ρ and the relative permittivity εr. These parameters

indicate the refi ning quality and purity of oils as well as the

aging and the dielectric losses occurring during operation.

Insulating fl uids are sensitive.

Even smallest impurities, air

intake, gas formation and humi-

dity affect their properties.

It is important to minimise

faults and effect on the sample

during handling. This is the

only way to get defi ned and

reproducible measuring

results. The optimisation of

measuring and switch-off

technology therefore is another

unique and innovative benefi t

from BAUR.

• With the BAUR KFM 3000 tester, the water content in

insulating oils is determined according to the Karl-Fischer

method. It allows the exact determination of even the

smallest quantities of water.

• The oil testing software, ITS, optimises the mostly tedious

but necessary post-processing, documentation, archiving and

comparability of measuring results.

In 1986 BAUR launches a water content measuring device

in the μg range with excellent properties for determining the

humidity in insulating oils according to the Karl-Fischer method.

In 1987 BAUR introduces oil testers with complete electro-

magnetic shielding which and thus allows error-free oil testing in

hi-tech laboratories with IT-infrastructure and gas chromato-

graphs.

In 1988 the BAUR DTL oil tester revolutionises testing

technology. It is the fi rst device combining automatic measuring

procedures for the dissipation factor and specifi c resistance of

insulating oils.

In 1989 BAUR introduces another innovative highlight: The

smallest portable oil tester with a test voltage up to 60 kV, ideal

for fi eld use with battery operation.

In 1995 BAUR develops the RBM technology. With the Real

Breakdown Monitoring, only actually completed breakdowns will

be identifi ed.

In 1996 BAUR converts all oil testers to power amplifi er

electronic voltage generation. This ensures stable test voltage

and limits the breakdown energy so that deposits on electrodes

caused by gas formation and carbonisation will be minimised.

In 2008 BAUR presents the completely new developed series

of oil testers. The BAUR DTA 100 C, BAUR DPA 75 C and BAUR

DTL C instruments are characterised by the most modern meas-

uring technology, maximum effi ciency and user-friendliness.

Milestones in the history of insulating fl uid testing:

In 1952 BAUR presents the

smallest oil tester for break-

down measurement of

insulating oils. The revolution-

ary, fi rst portable devices

enable onsite testing.

In 1965 BAUR introduces

the fi rst fully automatic oil

tester in the world. The device

working with a punched card

determined the mathematical

average value independently.

In 1968 Development of

the „BAUR Propeller“ for

circulation of the insulating oil during the complete test

sequence. With this method the dispersion of breakdown

series is improved and later incorporated in the US standard

ASTM D 1816.

In 1970 BAUR introduces the hermetically sealed oil test cell.

It keeps out ambient air and thus increases the precision of the

breakdown voltage. Equally innovative is the fi rst-time use of an

electronic triac switch-off in oil testers. It reduces the switch-off

time to < 1 ms, thus reduces the switch-off energy and reduces

the gas formation in the breakdown series.

In 1975 BAUR is the fi rst manufacturer to introduces a

transport test cell for taking oil samples. This minimises impuri-

ties in the sample during transport and curroption of the

measuring results.

Easy, quick and safe analysis

of insulanting fl uids with BAUR DTA 100 C.

The breakdown voltage test is used to evaluate the degree of

impurity in insulating oils due to foreign particles, gas and water.

It meets current regulations and is economically useful to

protect electrical systems such as transformers and switches,

as well as, medical and security systems from breakdowns. The

main reason for such damage is the poor condition of the

insulating oil.

The oil tester BAUR DTA 100 C, is designed for continuous opera-

tion in the laboratory. This high performance instrument is

characterised by the combination of extraordinary properties

such as a test voltage up to 100 kV, clear breakdown detection

and absolutely reliable measurement results. The BAUR DTA 100

C is the leading testing instrument for users in the electricity

industry, in testing institutes and other industrial applications.

More safety, effi ciency and profi tability.

Reliable and regular insulating oil testing with BAUR is used not

only for protection of systems but also for prevention of high

costs due to failures and accidents. It is highly economical to

defer high investments such as the replacement of insulating

oils as long as possible for an optimum exploitation. A cost

example: replacement of the insulating oil in an 80 MVA trans-

former at an oil price of 2.50 € and a requirement of about

15,000 litres means an investment of approx. 37,500 €. The life

time can be maximised through exact determination of the oil

quality, which subsequently improves the profi tability.
