where can I get current transformer leak rate

2021-2-26Calculating the burden of a Current Transformer. The burden of a current transformer is indicated in its nameplate. The burden is rated in VA. such as 15VA or 25 VA. The rated VA indicates the load the transformer can take. The current transformer is connected to a measuring instrument or a protective relay by means of wires.

  • What is Leakage Current? - Sunpower UK

    2021-3-7The filter manufacturers usually specify the maximum leakage current that the filter will leak, but these are only theoretical values and the actual values may deviate from these especially if parameters such as voltage or frequency change. To get an accurate value of the leakage current, it is advisable to measure the current

  • Fundamentals of leak detection - Leybold

    2017-1-12The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate
