Transformer Oil Breakdown Voltage Testing Services

To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its break down voltage is measured. The lower the resulting breakdown voltage, the poorer the quality of the transformer oil. The transformer oil is filled in the vessel of the testing device. Two standard-compliant test electrodes with a typical clearance of 2.5 mm are surrounded by the dielectric oil. A test voltage is applied to the electrodes and is continuously increased up to the breakdown voltage. At a certain voltage level breakdown occurs in an electric arc, leading to a collapse of the test voltage. An instant after ignition of the arc, the test voltage is switched off automatically by the testing device. The transformer oil testing device measures and reports the root mean square value of the breakdown voltage. After the transformer oil test is completed, the insulation oil is stirred automatically and the test sequence is performed repeatedly: typically 5 repetitions, depending on the standard. As a result the breakdown voltage is calculated as mean value of the individual measurements.

We have an efficient Break-Down Value (BDV) testing kit always ready with our filtration machines to check the resistance of filtered and purified oil. Generally, our clients have 25-35 KVA reading before filtration process of transformers oil. And yes, we are always succeeded to to get value of >80 KVA after filtration process. That's all because of our high quality and efficient machines. Many of the oil test required deep testing and are also time consuming for precise results, which cannot be undertaken on clients site. For that purpose too, we provide a deep analysis and testing service of transformer oil through sample taken after filtration. On that case, we also provide this testinb on certification of India's authorised association i.e. ERDA which is NABL approved. This deep analysis and testing services include various test such as physical test, BDV test, acedic test, moisture test, etc. These are total 9 tests which purely certifies the purity of oil on base of international standards. Without creating any complexities to our clients we are always pledged to remain present againts any working issue disturbing our clients regarding our services.

Transformer Oil Testing Transformer oils are subjected to electrical and mechanical stresses while a transformer or other electrical distribution equipment stays in operation. The analysis of insulating oil provides information about the oil, but also enables the detection of other possible problems, including contact arcing, ageing insulating paper and other latent faults and is an indispensable part of the cost-efficient electrical maintenance program. Though the risk of failure of a transformer and other oil-filled electrical equipment is small, when failures occur, they inevitably lead to high repair costs, long downtime and possible safety risks. By accurately monitoring the condition of the oil, sudden faults can be discovered in time and outages can potentially be avoided. Properties Of Transformer Or Insulating Oil Following parameters of insulating oil or transformer should be considered to analyse the serviceability of oil. Physical Parameters – Colour and Appearance, Density, Inter Facial Tension, Viscosity, Flash Point and Pour Point. Chemical Parameters – Water Content, Corrosive Sulphur, Acidity, Sludge Content. Electrical Parameters – Dielectric Strength, Specific Resistance, Dielectric Dissipation Factor. Dissolved Gas Analysis Furan Analysis PCB Analysis
