While observing the slug of insulating fluid, slowly crack the sample outlet valve open. Open the lower valve on the steel cylinder. To the running of this website, we need your help to support us. Do not pull thepiston manually since this can result in bubble formation. 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.

Package the filled syringe as soon as possible to protect the sample from light. A large variancefrom normal should be d3163 when evaluating the testresults obtained when the syringe conditioning was not used. Position the handle toward the syringe. With all three valves openand the cylinder held in a vertical position see Fig.

See Test Methods D for further details about generalcleaning requirements.

Wipe the inside of the valve and threads with a clean lint free cloth. Ethics for managements consultans. Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. Care must be taken in drawing samples to preventcontamination and to ensure a truly representative sample.

A number in parentheses indicates the year of last reapproval.

If the slug moves towards the electrical apparatus, a negative pressure exists. Care shall be taken not tocontaminate the syringe inlet port.

Satm the container is full, install thecap immediately. Wipe the inside of the valve and threads with a clean lint-free cloth. To minimizewaste and potential spills a length of 60 cm 24 in. Syringe Valve Piston Gases Materials.

The samples should notbe stored. Cleaning thetubing should be considered impractical. Wipethe inside of the valve and threads with a clean lint-free cloth.

Transformer Oil Gas Analyser (TOGA)

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. If air is present, discharge oil with the syringevertical stopcock up and obtain another sample. However, gas-saturated samples will begin to release gases bubbles soon after sampling. Close thestopcock, with the handle toward the syringe.

Install the drain valve security plug. Samples can be obtained safely. Remove the sample adapter if used, andreinstall the security plug with a non-hardening thread sealant. Connectthe oil-resistant tubing to the lower valve port on the steelcylinder and connect a short piece approximately 60 cm 24in.

If the slug moves away from the electrical apparatus, a positive pressure exists. Take extreme caution when samples are drawn from electrical apparatus having a small volume of insulating fluid. Packaging and Shipping Samples can beobtained safely. Perform this condition procedure onemore time. One of two procedures may then be used to prepare the sample outlet.

If the slug moves towardsthe electrical apparatus, a negative pressure exists. Thank you for visiting our website and your interest in our free products and services.

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. Do not release any evolved gases bubbles since these gases must be included in the dissolved gas analysis. Do not release any evolvedgases bubbles since these gases must be included in thedissolved gas analysis. If the slug moves away from theelectrical apparatus, a positive pressure exists.
