Six laboratories in Japan have performed round-robin test (RRT) on measurement of repetitive PD inception voltage (RPDIV) under well-controlled experimental condition. They used common twisted-pair sample, common impulse generator and common data sheet with normalized air pressure and temperature. Scatterings of data were small except in relative humidity.(More)
The Taft's substituent constant of the pentafluorophenyl group (sigma(C(6)F(5))) was reestimated to be 1.50 by correlation between IR spectral data (v(C)(=)(O)) and sigma constants for a series of esters (involving the pentafluorobenzyl group) of 3-phenylpropanoic acid and butanoic acid. The possibility of the disturbance of the correlation by the(More)
