However, gas-saturated samples will begin to release gases bubbles soon after sampling.

Care shall be taken not tocontaminate the syringe inlet port. Do not release any evolvedgases bubbles since these gases must be included in thedissolved gas analysis.

Position the handle toward the syringe. Samples can beobtained safely. Install the drain valve security plug. Last previous edition D — Flush the valve at installed sample adapter, flushing at least one more quart of fluid into the flush oil container before collecting sample.

Remove the security pipe plug from the drain valve. Immediately close the port into the syringe Fig. Wipe the inside of the valve and threads with a clean lint-free cloth. However, gas-saturated samples will begin to release gases bubbles soon after sampling. If you have any questions about copyright issues, please report us to resolve them.

Transformer Oil Gas Analyser (TOGA)

Test Method D, Table 1, provides coefficients of variation for different gas-in-oil analysis from samples collected in the three containers recommended in this practice. While observing the slug of insulating fluid, slowly crack the sample outlet valve open. To minimizewaste and potential spills a length of 60 cm 24 in. One of two procedures may then be used to prepare the sample outlet. Cleaning thetubing should be considered impractical.

Originallypublished as D — Extreme care should be used in performing this procedure. Immediately close the port to thesyringe Fig. Syringe Valve Piston Gases Materials. It isdesirable that stainless steel cylinders be evacuated and sealedafter cleaning.

Do not pull thepiston manually since this can result in bubble formation. Drain at least 1. Collecting Samples Using Syringe 8. Attach the plastic tube tothe syringe as shown in Fig.

Open the lower valve on the steel cylinder. Separate the syringe from the tubing and inspect forair bubbles. With all three valves openand the cylinder held in a vertical position see Fig. We are nonprofit website to share and download documents.

Wipe the inside of the valve and threads with a clean lint free cloth. Preparation for Sampling 6. Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. The tubing should not be reused.

If the slug moves away from the electrical apparatus, a positive r3613 exists. Do not release any evolved gases bubbles since these gases must be included in the dissolved gas analysis.

If the slug moves towardsthe electrical apparatus, a negative pressure exists. If any sound is heard,the cylinder should be drained and the sampling repeated. Cleaning of Apparatus 5.
