Type text as adtm appears:: 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 The quality of the insulating oil must be checked at regular intervals astk ensure a long equipment service life. The voltage in the test circuit should be stable enough to be unaffected by varying current flowing in the capacitive and resistive paths of the test circuit.

Hipotronics TCVDE Oil Dielectric Test Cell for ASTM D1816 testing
Tightly seal and shield from light until ready to be tested. The spacing agreed upon shall be measured with the gage that corresponds exactly to the selected spacing within tolerance stated above for the gage.
What are your requirements. Oil sampling procedures are detailed in Practice D After thorough cleaning, c1816 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.

However, a high dielectric breakdown voltage does not necessarily indicate the absence of all contaminants; it may merely indicate that the concentrations of contaminants that are present in the liquid between asm electrodes are not large enough to deleteriously affect the average breakdown voltage of the liquid when tested by this test method see Appendix X1.

Flat “go” and “no-go” gages may be substituted having thicknesses of the specified value more or less 0. Request a Free Quote Right Now.
The sample shall be taken in a dry, clean, non-permeable bottle. After adjustment of the spacing, rinse the cell with a dry hydrocarbon solvent, such as kerosine or solvents of Specification D Construct the test cell of a material of high dielectric strength, that is not soluble in or attacked by any of the cleaning or test liquids used, and is nonabsorbent to moisture and the cleaning and test liquids.
Work Item s – proposed revisions of this standard. A test cell having a capacity of 0.

Alternatively, the cell may be stored empty in a dust-free cabinet. If it is necessary to readjust the electrodes, lock asgm electrodes and check the spacing. Determination of the dielectric breakdown voltage of insulating oils provides an early detection method for any reduction in the insulating properties. 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.
The impeller, located below the lower edge of the electrodes, rotates in such a direction that the resulting liquid flow is directed downward against the bottom of the d186 cell. If this occurs, before using, warm the cell to evaporate the moisture.
