EQUIPMENTS REQUIRED. China Oil Dielectric Strength Test catalog of Dielectric Strength Testing Machine Transformer Oil Tester Equipment Bdv Test Kit, Transformer Insulating Oil Dielectric Strength Testing Device, Breakdown Voltage Tester provided by China manufacturer - Huazheng Electric Manufacturing (Baoding) Co., … 1.1 This test method covers the determination of the dielectric breakdown voltage of insulating liquids (oils of petroleum origin, silicone fluids, high fire-point mineral electrical insulating oils, synthetic ester fluids and natural ester fluids). Breakdown strength voltage is measured as the voltage at which spark plugs between the two electrodes that are dipped in the oil, isolated by a particular distance. It is done for checking the dielectric strength of the oil of the Transformer. Paraffin dependent oil; Naphtha dependent oil; Of these two, naphtha oil has more oxidizing properties, but the sludge of naphtha oil has increased solubility than paraffin oil. The results are given in kV/mm. The transformer dielectric oil tester set has been specially designed for testing the dielectric breakdown voltage strength of insulating liquids, a very high voltage is passed through it. The failure of the dielectric strength is shown by a spark across two electrodes. These lightweight, rugged units are designed for field and laboratory use.. www.electric-test.com. Dielectric breakdown voltage in the range of 28kV or more; Pour point is at -40 0 C or less than this; Flashpoint of 140 0 C; Different Types. Transformer Oil Bdv Tester, Dielectric Strength, Dielectric Strength Tester manufacturer / supplier in China, offering ASTM D1816 ASTM D877 Standard Transformer Oil Breakdown Voltage Test Equipment, Transmitter and Receiver Sewer 512Hz Underground Cable Pipe Locator Price, 3 Phase Current Primary Injector 1000A Primary Injection Test Set and so on. The dielectric test of transformer is generally performed in two different steps, likewise, separate source voltage withstand test and induced voltage withstand test of transformer, which we have discussed one by one below.. 7 All of these oil types can be tested for dielectric breakdown voltage and tested with Megger OTS range test sets. The DTS Series provides repeatable and accurate measurements of the breakdown voltage of insulating oils used in electrical equipment. Transformer oil testing for dielectric strength Vessel preparation and elimination of the effects of moisture and contamination play a major role in successful oil testing. Keywords: Power transformers, Insulating oil, Impurities, Electrode configurations, Voltage types . BAUR Dielectric Strength Oil Testers. These dielectric strength test of transformer oil are equipped with hydraulics for conducting compression tests and come with distinct power capacities. The test gives a good indication of the amount of contaminants (water and oxidation particles) in the oil. OBJECTIVE. The test cell shall be of glass or plastic and transparent and non-absorbent (Eg. There are mainly two types of transformer oil and those are:. How to proceed the Dielectric Strength Test for transformer oil? 1) includes test transformer that can generate 100 kV (AC), test. Transformer oil is a form of insulating and cooling oil to use in transformer and other electrical equipment.This oil that maintains stable at high temperature and has great specialized properties. In the last five decades in India, there is a drastic change in production technology. Transformer Oil Tests That Should Be Completed Annually with the Dissolved Gas Analysis Dielectric Strength This test measures the voltage where the oil electrically breaks down. Lastly, take approximately (1) litre of oil for dielectric strength test and other test required to ascertain health oil. This observation is in agreement with theoretical predictions of Gupta and Sen [8] , where the dielectric breakdown was studied in a semi-classical bond percolation model for a non-linear composite material. BDV test means Breakdown Voltage Test. 1,887 transformer oil dielectric strength test products are offered for sale by suppliers on Alibaba.com, of which testing equipment accounts for 52%. Experiment - 4. DGA laboratories typically use ASTM D-1816. SG7808 - Shanghai Jiuzhi Electric Co., Ltd. For many electric equipments used in power system and enterprises, inner insulation is mostly oil-insulated. This application note points to the precautions that need to be taken. Dielectric strength refers to the maximum ability to withstand the voltage of the insulating oil. These dielectric strength test of transformer oil are comprised of automated technologies that offer precise analysis and details on the outcome of a test phase. Watch Queue Queue This test is conducted using the international standard ASTM D877 which also specifies that the new transformer oil should have a minimum dielectric strength of 35kV. – The dielectric capability of the transformer oil (dielectric strength of transformer oil) depends on the breakdown strength (BDV) of transformer oil. BDV test is used to test or check the quality of transformer oil. For example, for a 1500-V-ac voltage, the equivalent dc voltage to produce the same amount of stress on the insulation would be 1500 x 1.414 or 2121 V dc. The BDV is measure in kV. 3.10 DIELECTRIC STRENGTH. The BDV test of transformer oil is a breakdown voltage test. SG7808 Oil Dielectric Test Set is the ideal testing device for oil dielectric strength. INTRODUCTION This dielectric test is intended to check the the ability of main insulation to earth and between winding. Breakdown voltage is an important test for transformer oil. To measure the dielectric strength of transformer oil. Therefore, if we use dc test voltage, we ensure that the dc test voltage is under root 2 (or 1.414) times the ac test voltage, so the value of the dc voltage is equal to the ac voltage peaks. It is quite simple to perform, so its results are very easy to use as a reference value in the comparison of data from different trials. So, it is mainly used in an oil filled transformer to the electrical and automotive industry. Dielectric Strength of an insulating material is influenced by the fabrication details For example, flow lines in a compression molding or weld lines in an injection molding may serve as paths of least resistance of leakage currents, this reducing the dielectric strength.
