Connectthe ashm tubing to the lower valve port on the steelcylinder and connect a short piece approximately 60 cm 24in. Last previous edition D — Extreme care should be used in performingthis procedure. Power by seonoco All Rights Reserved: If d36613 slug moves away from the electrical apparatus, a positive pressure exists.
Wipe the inside of the valve and threads with a clean lint free cloth. A number in parentheses indicates the year of last reapproval.
Transformer Oil Gas Analyser (TOGA)
Samples can beobtained safely. If any sound is heard,the cylinder should be drained and the sampling repeated. 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. Drain at least 1. Do not pull thepiston manually since this can result in bubble formation.
Packaging and Shipping Flush the valve at installed sample adapter, flushing at least one more quart of fluid into the flush oil container before collecting sample.
Preparation for Sampling 6.
Immediately close the port to thesyringe Fig. With all astj valves openand the cylinder held in a vertical position see Fig. If air is present, discharge oil with the syringevertical stopcock up and obtain another sample. Cleaning of Apparatus 5. Package the filled syringe as soon as possible to protect the sample from light. Remove the sample adapter if used, andreinstall the security plug with a non-hardening thread sealant.
Collecting Samples Using Syringe 8. A large variancefrom normal should be considered when evaluating the testresults obtained when astk syringe conditioning was not used. Close thestopcock, with the handle toward the syringe. Drain at least 1. Samples can be obtained safely. The filled syringe should contain no air.
Cleaning thetubing should be considered impractical.
Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. Immediately close the port into the syringe Fig. Install the drain valve security plug.
Care shall be taken not tocontaminate the syringe inlet port. 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 from the drain valve. While observing the slug of insulating fluid, slowly crack the sample outlet valve open. Current edition approved April 10, When thedrying period has expired, syringe pistons shall be placed intheir barrels, valves dd3613 stainless steel cylinder valvesshould be closed; or cans sealed with their screw cap.
Take extreme caution when samples are drawn from electrical apparatus having a small volume of insulating fluid. Position the handle toward the syringe. We are always happy to assist you. Samples should be forwardedto the laboratory as quickly as possible. Open aztm lower valve on the steel cylinder.
