WebbThe trade-off theory of capital structure is the idea that a company chooses how much debt finance and how much equity finance to use by balancing the costs and benefits. The classical version of the hypothesis goes back to Kraus and Litzenberger [1] who considered a balance between the dead-weight costs of bankruptcy and the tax saving benefits of … WebbThe commutation principle for HVDC circuit breakers is described whereby the current in the circuit is brought to zero by a bucking current from a precharged capacitor. Circuit features are described to render this procedure easier for the interrupter and typical component requirements are discussed. The functions of current interruption and … solli bowling booking

WebbThe calculation of the short-circuit capacity of a power system is very involved and complex. Conservatively, it can be as high as 20–30 times the normal full-load current of … WebbBy assuming the maximum phase of the tank current, we obtain a relation for the lock range. Besides, the effects of parasitic capacitors on the lock range have been probed. The analysis shows that the greater the phase difference between the tail current and injected signal, the phase of the tank current increases and, consequently, the lock range also …
