Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. Ethics for managements consultans. Remove the security pipe plug fromthe drain valve. Cleaning of Apparatus 5. Install the drain valve security plug. Thank you d361 visiting our website and your interest in our free products and services. Extreme d361 should be used in performing this procedure. Collecting Samples Wstm Syringe 8. Current edition approved April 10, A large variancefrom normal should be considered when evaluating the testresults obtained when the syringe conditioning was not used.
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. It isdesirable that stainless steel cylinders be evacuated and sealedafter cleaning. Epidemiology, pathogenesis, and clinical manifestations of Ebola and Marburg virus disease.
While observing the slug of insulating fluid, slowly crack the sample outlet valve open. We are always happy to assist you.
Extreme care should be used in performingthis procedure. Immediately close the port to thesyringe Fig. Samples should be forwardedto the laboratory as quickly as possible.
Immediately close the port into the syringe Fig.
Transformer Oil Gas Analyser (TOGA)
These cylindershave the disadvantage of not allowing visual inspection of theinterior of the cylinder. 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 wstm collecting the fluid in the sample container. The filled syringe should contain no air. Packaging and Shipping Samples can be obtained safely. If the slug moves away from theelectrical apparatus, a positive d3631 exists.
Drain at least 1. Separate the syringe from the tubing and inspect forair bubbles.
A number in parentheses indicates the year of last reapproval. When thedrying period has expired, syringe pistons shall be placed intheir barrels, valves closed; stainless steel cylinder valvesshould be closed; or cans sealed with their screw cap.
Connectthe oil-resistant tubing to the axtm 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. Perform this condition procedure onemore time. The tubing should not be reused. Sampling should be discontinued.

Wipe the inside of the valve and threads with a clean lint-free cloth. Position the handle toward the syringe. Power by seonoco All Rights Reserved: However, gas-saturated samples will begin to release gases bubbles soon after sampling.
If the slug moves towardsthe electrical apparatus, a negative pressure exists. Last previous edition D —
