Electricity Group, MIKES, Espoo
Abstract :
Overview of the sources of dc and ac ratio errors in conventional cryogenic current comparator (CCC) is presented. Preliminary results of the measurements of ac ratio error in overlapped-tube type CCC are given. The measured maximum deviation from the nominal ratio in CCC used in MIKES is less than 2 ppm in frequency range 0-200 Hz
