| Outline of Final Research Achievements |
We have developed a high performance damped capacitive voltage divider and evaluated its response after measuring unit step response. The developed voltage divider significantly differ from the conventional same type divider in high voltage arm. Whilst 70kV class ceramic capacitors are piled up in the conventional type, newly developed divider's main column consists of strings of 4kV capacitors. The strings are wound spirally in opposite direction so that magnetic field generated by each string cancels each other. Divider's standard lightning impulse responses were evaluated by numerical convolution using measured unit step response. It was confirmed that T1-error was around 0.2% which is the level almost impossible to measure by today's technology.
