EI2435 Faults and Transients on Transmission Lines Wang Wei weiwan@kth.se 1/12/2011 1. Introduction Project 1 is about fault currents and transients on transmission lines that may occur due a lightning strike to an overhead line. In this case the transmission line is energized from one side and it’s other side is terminated in a Gas Insulated Substation‚ see Fig. 1. Several issues will be investigated from this system such as transient overvoltages and short-circuit currents. Fig.1 Transmission

I thought my life had ended and I thought that I would never think a thought again‚ but suddenly I realised that although I had been separated from my body‚ my Ba and Ka were floating around‚ following my body and watching its every move.

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)
