9- Suggest that you are an electrical power engineer with the Iraqi National Grid (ING ), you need to protect a power transformer of 132 KV / 11 KV against overvoltage, if the electrical discharge breakdown field strength = 90 MV / m and the distance between the electrodes 1 Cm, and the BIL = 630 KV, the rate of rise of waveform of overvoltage = 900 KV/S. Find the allowable worst location of the Surge .Diverter a- The allowable worst location of the Surge Diverter at : 33.5 m. b-) All these answers are wrong. C- The allowable worst location of the Surge Diverter at: 28.33 m. d- The allowable worst location of the Surge Diverter at : 30 m. %3D %3D
