Insulating uids are a key component of much electricalequipment. Highly re ned mineral oils, silicone uids, vegetableoil (natural esters) and synthetic esters guarantee the operationof transformers, medical and safety or even radar technologydevices. Insulating materials lose their insulating and coolingproperties due to impurities and ageing. The consequencesinclude damage and failures of equipment and systems, evencatastrophic failures resulting in transformer res and the

consequent costs and environmental damage.

The testing of insulating uids is therefore legally stipulated andregulated through national and international standards. Equallyimportant are the economic reasons for regular testing toinclude extended lifetime of equipment and optimal use ofinsulanting oils to achieve enormous potential savings.

A good investment to avoid high costs.

Insulating uids testing with BAUR.

BAUR oil testers are characterised by quality recognisedworldwide. Quality in the de nition of BAUR and its customersare not empty words. It is determined by criteria which have adirect 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 pro table for the customer.

Maximum quality, reliability and precision for the safety and pro tability of your facilities.

• The extremely ef cient laboratory instrument BAURDTA 100 C for continuous operation and the mobile testerBAUR DPA 75 C are used for breakdown voltage tests andsubsequently to determine the degree of impurity due toexternal particles and water.

• The unique laboratory device worldwide BAUR DTL C , isused to determine the dissipation factor tan δ , the speci cresistance ρ and the relative permittivity ε r. These parametersindicate the re ning quality and purity of oils as well as theaging and the dielectric losses occurring during operation.

Insulating uids are sensitive. Evensmallest impurities, air intake, gasformation and humi- dity affect their properties.It is important to minimise faults andeffect on the sample during handling. Thisis the only way to get de ned andreproducible measuring results. The

optimisation of measuring and switch-offtechnology therefore is anotherunique and innovative bene t from BAUR.

• With the BAUR KFM 3000 tester , the water content ininsulating oils is determined according to the Karl-Fischermethod. It allows the exact determination of even thesmallest quantities of water.

• The oil testing software, ITS , optimises the mostly tediousbut necessary post-processing, documentation, archiving andcomparability of measuring results.

Well thought out and up-to-the-minute details.The new generation of BAUR oil testers.

5/205

In 1986 BAUR launches a water content measuring devicein the µg range with excellent properties for determining thehumidity 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 inhi-tech laboratories with IT-infrastructure and gas chromato-graphs.

In 1988 the BAUR DTL oil tester revolutionises testingtechnology. It is the rst device combining automatic measuringprocedures for the dissipation factor and speci c resistance ofinsulating oils.

In 1989 BAUR introduces another innovative highlight: Thesmallest portable oil tester with a test voltage up to 60 kV, idealfor eld use with battery operation.

In 1995 BAUR develops the RBM technology. With the RealBreakdown Monitoring, only actually completed breakdowns willbe identi ed.

In 1996 BAUR converts all oil testers to power ampli erelectronic voltage generation. This ensures stable test voltageand limits the breakdown energy so that deposits on electrodescaused by gas formation and carbonisation will be minimised.

In 2008 BAUR presents the completely new developed seriesof oil testers. The BAUR DTA 100 C, BAUR DPA 75 C and BAURDTL C instruments are characterised by the most modern meas-

uring technology, maximum ef ciency and user-friendliness.

Milestones in the history of insulating uid testing:

In 1952 BAUR presents thesmallest oil tester for break-down measurement ofinsulating oils. The revolution-ary, rst portable devicesenable onsite testing.

In 1965 BAUR introducesthe rst fully automatic oiltester in the world. The deviceworking with a punched carddetermined the mathematicalaverage value independently.

In 1968 Development ofthe „BAUR Propeller“ forcirculation of the insulating oil during the complete testsequence. With this method the dispersion of breakdownseries 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 thebreakdown voltage. Equally innovative is the rst-time use of anelectronic triac switch-off in oil testers. It reduces the switch-offtime to < 1 ms, thus reduces the switch-off energy and reducesthe gas formation in the breakdown series.

In 1975 BAUR is the rst manufacturer to introduces atransport test cell for taking oil samples. This minimises impuri-

ties in the sample during transport and curroption of themeasuring results.

The breakdown voltage test is used to evaluate the degree ofimpurity in insulating oils due to foreign particles, gas and water.It meets current regulations and is economically useful toprotect electrical systems such as transformers and switches,as well as, medical and security systems from breakdowns. Themain reason for such damage is the poor condition of theinsulating oil.

The oil tester BAUR DTA 100 C, is designed for continuous opera-tion in the laboratory. This high performance instrument ischaracterised by the combination of extraordinary propertiessuch as a test voltage up to 100 kV, clear breakdown detectionand absolutely reliable measurement results. The BAUR DTA 100C is the leading testing instrument for users in the electricityindustry, in testing institutes and other industrial applications.

Reliable and regular insulating oil testing with BAUR is used notonly for protection of systems but also for prevention of highcosts due to failures and accidents. It is highly economical todefer high investments such as the replacement of insulatingoils 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 about15,000 litres means an investment of approx. 37,500 €. The lifetime can be maximised through exact determination of the oilquality, which subsequently improves the pro tability.

Permanent and safe analysis of insulating oils with

BAUR DTA 100 C Inline.

The BAUR DTA 100 C Inline is a high performance and reliable oiltester for continuous testing of the breakdown strength ofinsulating oils during production (Inline tests). The combinationof extremely short switch-off times during breakdowns and theeasy oil sample handling facilitate high quality statements andconclusions on the insulating oil quality. Standard connectionsfor oil inlet and outlet and the possibility to integrate in existingproduction processes (e.g. PLC control) enable easy andautomated oil testing. In addition to these properties, the

archiving and clear allocation of measurement results is greatlysimplified and made faster when combined with the BAURsoftware ITS Lite owing to the fully automated measurementdata export.

The BAUR DTA 100 C Inline enables cost-effective testing of thebreakdown strength of insulating oils during the oil preparationand thereby delivers exact information on the quality of theinsulating oil. Active production processes need not be interrup-ted for it. This gives you continuous control on the status of yourinsulating oil. This saves time and money. Connecting the BAURoil tester to your production control enables efficient monitoring
