The spacing agreed upon shall be measured with the gage that corresponds exactly to the selected spacing within tolerance stated above for the gage.
High Voltage Inc TCD-5 Test Cell 60KV – ASTM D1816 test specs
Do not use a low boiling point solvent, as its rapid evaporation may cool the cell, causing moisture condensation. At the beginning of each days testing, clean according to 7. In order to preclude stirring air with the sample, provide dd1816 cell with a cover or baffle that will effectively prevent air asmt contacting the circulating liquid.
This test method should be used as recommended by professional organization standards such as IEEE C ASTM Method being used?
If this occurs, before using, warm the cell to evaporate the moisture. Contact with us now Your mail: Calibration s shall be traceable to national standards and calibration should be verified annually or more often to ensure accuracy requirements.
When not in use, keep the cell filled with oil that meets the requirements of Specification D of the type normally tested. USB memory stick Operating Temperature: Right-click to open the PDF in a new window or download it: So that the breakdown may be observed, transparent materials are desirable, but not essential.
Oil sampling procedures are detailed in Practice D Email Us or call toll-free: Calibrate and label automatic controls in terms of rate-of-rise. The sample shall be taken in a dry, clean, non-permeable bottle. 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 the electrodes are not large enough to deleteriously d116 the average breakdown voltage of the liquid when tested by this test method see Appendix X1.
Work Item s – proposed revisions of this standard. A test cell having a capacity of 0.
It has been found to be especially useful in diagnostic and laboratory investigations of the dielectric breakdown strength of insulating liquid in insulating systems. Looking for a specific close-up? 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, Construct the test cell of a material of high dielectric strength, that is not soluble in or attacked by any of awtm cleaning or test liquids used, and is nonabsorbent to moisture and the cleaning and test liquids.
What are your requirements. Ast, the cell may be stored empty in a dust-free cabinet. Tightly seal and shield from light until ready to be tested.
Up to 75kV rms symmetrical Voltage measurement accuracy: The most important requirement of an insulating oil is a high dielectric strength. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Refer to Terminology D for definitions used in this test method. The equipment should produce a straight-line voltage-time curve over the operating range of the equipment. The test cell shall be designed to permit easy removal of the electrodes for cleaning and polishing, verification that the shape is within the specified tolerance, and to permit easy adjustment of the x1816 spacing.
A cell aastm a capacity of 0. 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. Flat “go” and “no-go” gages may be substituted having thicknesses of the specified value more or less 0.
Measurement of oil temperature: Reinstall the electrodes in the test cup and adjust spacing and clean in accordance with 7.
