Extreme care should be used in performingthis procedure. Attach oil-resistant tubing to the sample port on the drain valve and flush at least one more quart of fluid into the flush-oil container before collecting the fluid in the sample container.

Open the lower valve on the steel cylinder. Install the drain valve security plug. See Test Methods D for further details about generalcleaning requirements.

Extreme care should be used in performing this procedure. This should involve a volumeof air equivalent to at least 55 changes of the cylinder volumeduring the 15 min period of drying.

Ethics for managements consultans. If any sound is heard,the cylinder should be drained and the sampling repeated. Care shall be taken not tocontaminate the syringe inlet port. Last previous edition D — Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. Remove the security pipe plug from the drain valve. Test Method DTable 1,provides coefficients of variation for different gas-in-oil analy-sis from samples collected in the three containers recom-mended in this practice.

If the slug moves away from the electrical apparatus, a positive pressure exists. Immediately close the port into the syringe Fig.

Contact with us now Your mail: Do not release any evolvedgases bubbles since these gases must be included in thedissolved gas analysis. Wipe the inside of the valve and threads with a clean lint free cloth. Samples can be obtained safely. However, gas-saturated samples will begin to release gases bubbles soon after sampling.

Do not release any evolved gases bubbles since these gases must be included in the dissolved gas analysis. Asuperscript epsilon v3613 indicates an editorial change since the last revision or reapproval. Sampling aetm be discontinued.

To minimizewaste and potential spills a length of 60 cm 24 in. Drain at least 1.

Preparation for Sampling 6. It isdesirable that stainless steel cylinders be evacuated and sealedafter cleaning.

Connectthe oil-resistant tubing to the lower valve port on the steelcylinder and connect a short piece approximately 60 cm 24in. Flush the valve at installed sample adapter, flushing at least one more quart of fluid into the flush oil container before collecting sample.

The air may be dried bypassing the air through two drying towers in series, each toweris at least 9 cm diameter and 28 cm in height. Remove the security pipe plug fromthe drain valve. Once the container is full, install thecap immediately.

Attach the plastic tube tothe syringe as shown in Fig. Convenient cardboard cartons for storing and trans-porting syringes can be obtained.

Do not allow the oil to be exposed tosunlight. One of two procedures may then be used to prepare the sample outlet. Power by seonoco All Rights Reserved: We Need Your Support.

Wipe the inside of the valve and threads witha clean lint free cloth. All materials on our website are shared by users. Do not pull thepiston manually since this can result in bubble formation. Samples should be forwardedto the laboratory as quickly as possible.

The samples should notbe stored.

Chalmers The Components of Content. If the slug moves away from theelectrical apparatus, a positive pressure exists.

Originallypublished as D — If air is present, discharge oil with the syringevertical c3613 up and obtain another sample. Close thestopcock, with the handle toward the syringe. Immediately close the port to thesyringe Fig. Separate the syringe from the tubing and inspect forair bubbles. Cleaning of Apparatus 5. Wipe the inside of the valve and threads with a clean lint-free cloth.

Perform this condition procedure onemore time.
