DMGNOSlICS OF HIGH VOLWGE METAI, OXIDE ARlWSTENS PUOC!EDUUE ERUORS

A tcchniqnc has been describcd which can determine ac resistive current directly or by obtaining the watt loss of the tcst specimen and dividing by the true rms (trms) value or the applicd voltagc. Thc procednre errors with standard voltage dividers and digital systems have been calculated. Spccial attcntion was paid to thc voltage shift A ncw method for thc dircct resistive current measurement was proposcd. Tlic effect of small amount of harmonics was shown. .-{ 1~ r~~~.~. }-.~~~~../, I' jR/ - ~~~~~~
