advantages of Converter Station leakage

Feb 06, 2017The leakage reactance of the transformer is chosen to limit the short circuit currents through any valves. The converter transformers are designed to withstand DC voltage stresses and increased eddy current losses due to harmonic currents. One problem that can arise is due to the DC magnetization of the core due to unsymmetrical firing of valves.

  • 14 Advantages and Disadvantages Of Natural Gas

    Leakage: Even though it is lighter than air and can disperse easily, a big danger with natural gas is that since it is colorless, odorless and tasteless, should it start leaking, detection of the leak is very hard. Advantages of Natural Gas. Storage: Even though natural gas is easier to store and transport, it has one big disadvantage. Its volume happens to be four times that of petrol which makes it more expensive to store since more needs to be spent on additional storage.
