Refer to Terminology D for definitions used in this test method.

If the test of any sample is below the breakdown value being used by the operator as a minimum satisfactory value, drain the cell and flush the cell with new oil d18816 the type to be tested that is filtered through a 5-micron filter and containing less than 25 ppm moisture before testing the next specimen. Conduct a voltage breakdown test on a specimen of this oil in the manner specified in this test method.

The equipment should produce a straight-line voltage-time curve over the operating range of the equipment. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Oil sampling procedures are detailed in Practice D Construct the test cell of a material of high dielectric strength, that is not soluble in or attacked asgm any of the cleaning or test liquids used, and is nonabsorbent to moisture and the cleaning and test liquids.

Measurement of oil temperature: Right-click ast, open the PDF in a new window or download it: The impeller, located below the lower d18166 of the electrodes, rotates in such a direction that the resulting liquid flow is directed downward against the bottom of the test cell.

At the beginning of each days testing, clean according to 7. Plastic bottles are permeable and moisture content of the sample may change resulting in a measurable difference when compared to samples collected in non-permeable containers.

Looking for a specific close-up? Reinstall the electrodes in the test cup and adjust spacing and clean in accordance with 7.

Tightly seal and shield from light until ready to be tested. IEEE Standard 4 is required during the manufacturing of the test apparatus and utilized during calibration of atm equipment.

Work Item s – proposed revisions of this standard. After careful inspection, any electrodes from which pitting cannot be removed by light buffing should be discarded, as more ast would destroy the electrode contour and dimensions shown in Fig.

Petroleum Products and Biofuel lab apparatus baths, calorimeters, color measurement, density meters, flash point, hydrogenators, oil testing, penetrometers, surface tension, vapor pressure, viscometers and rheometers, The sample shall be taken in a dry, clean, non-permeable bottle.

If the breakdown voltage is in the expected range for this conditioned oil, the cell is considered properly prepared for testing other samples. Automatic equipment should be used to control the voltage rate of rise because of the difficulty of maintaining a uniform voltage rise manually. Do not use a low boiling point solvent, as its rapid evaporation may cool the cell, causing moisture condensation.

A cell having a capacity of 0. ASTM Method being used? After thorough cleaning, flush the cell with new oil of the type to be tested that is filtered through a 5-micron filter and containing less than 25 ppm moisture. Mount the electrodes rigidly from opposite sides with the spacing axially centered within more or less 1 mm. For referee tests or tests that will be used for close comparisons, the laboratories shall agree in advance on the spacing for the tests and ensure that all other requirements of this test method are met.

Product Description The majority of high-voltage transformers, cables, switchgears, transducers, capacitors, and rectifiers use insulating oils for insulating electrically live parts and to carry off thermal energy.

Power by seonoco All Rights Reserved: So that the breakdown may be observed, transparent materials are desirable, but not essential. This test method is applicable to insulating liquids commonly used in cables, transformers, oil circuit breakers, and similar apparatus as an insulating and cooling medium.

In order to preclude stirring air with the sample, provide the cell with a cover or baffle that will effectively prevent air from f1816 the circulating liquid. Wstm Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Flat “go” and “no-go” gages may be substituted having thicknesses of the specified value more or less 0. This test method should be used as recommended by professional organization standards such as IEEE C Determination of the dielectric breakdown voltage of insulating oils provides an early detection method for any reduction in the insulating properties.
