Storing oil samples properly before conducting transformer turns ratio (TTR) testing is crucial to maintain the integrity of the samples and ensure accurate test results.

Here are the requirements for storing oil samples before TTR testing:

  1. Clean Containers: Oil samples should be stored in clean and dry containers to prevent contamination. Use containers made of materials compatible with transformer oil, such as glass or high-density polyethylene (HDPE) bottles.
  2. Sealed Containers: Ensure that the containers used for storing oil samples are tightly sealed to prevent exposure to air and moisture, which can lead to oxidation and degradation of the oil.
  3. Labeling: Each container should be clearly labeled with relevant information, including the date and time of sampling, the location of sampling (e.g., transformer name or identification number), and any other pertinent details. Proper labeling helps track and identify the samples accurately.
  4. Storage Conditions: Store the oil samples in a cool, dark, and dry environment away from direct sunlight and sources of heat. Avoid storing samples in areas prone to temperature fluctuations or extreme temperatures, as these conditions can affect the properties of the oil.
  5. Protection from Contaminants: Take precautions to prevent contamination of the oil samples during storage. transformer turns ratio tester Keep the containers away from sources of dust, dirt, chemicals, and other contaminants that could compromise the integrity of the samples.
  6. Handling Procedures: Follow proper handling procedures when transferring oil samples into storage containers to minimize the introduction of air bubbles or foreign particles. Use clean utensils and equipment for handling the samples.
  7. Timely Analysis: Ideally, analyze the oil samples for TTR testing as soon as possible after sampling to minimize the potential for changes in the oil properties over time. If immediate analysis is not possible, store the samples for the shortest duration feasible under the recommended storage conditions.

By adhering to these requirements for storing oil samples before TTR testing, you can help ensure the accuracy and reliability of the test results, which are essential for assessing the condition of transformers and making informed maintenance decisions.
