  • How to Establish an Acceptable Leak Rate - Leak Testing

    • The characteristics of the hole (or leak) that determine whether it will leak are the smallest diameter in the hole path, the path length of the hole through the part material, surface tension, and the surface finish of hole (leak). Hole Size - The smallest opening in the flow (leak) path controls the rate of flow through the path.

  • Oil-level monitoring for pole mounted transformers | Digital

    The loss of transformer oil is one of the most common causes of the high failure rate. This oil is used to cool the coils inside the transformers and keep them insulated from each other. In poorly maintained devices, where the housings are badly rusted or cracked, the oil can leak out.

  • Guide to Good Leak Testing - US EPA

    Commercial and industrial refrigeration and air conditioning systems leak too much refrigerant – leaks of up to 30% of the charge during a year are not uncommon. Leak rates do not have to be this high. Adherence to best practice in service, maintenance leak testing and repair can significantly reduce refrigerant losses. This guide shows you how.

The origin of the defects is not simple. Generally, it is the combination of many factors that can be classified in the following way // 1. Imperfection on the specifications 1. Mistake in the selection of the type of insulation. 2. Not appropriate capacity. 3. Lack of attention to the conditions in the place of installation (dampness, temperature, dangerous gases, etc) 2.

  • Significance of CO2/CO ratio in - Transformers Magazine

    AbstractIntroductionCarbon Monoxide and Carbon Dioxide in Transformer OilCase 1According to the literature, the ratio of carbon dioxide and carbon monoxide (CO2/CO) for a transformer with a healthy cellulose insulation system should be between 3 and 11. If results of the dissolved gas analysis (DGA) of oil from transformers in service give the ratio value of CO2/CO less than 3, it means that the cellulose insulation is degrading rapidly. What is the meaning of this ratio if it is high; say greater than 15 or 20? Keywords:carbon monoxide, carbon dioxide, ratio, dissolved gas analysis
