Abstract :
When connecting thermal current converters (TCC) in series for calibration of current ac/dc difference, attention has to be paid to the various current leakages that may occur. The series connection has been modelled and a specially designed "T-piece" constructed. Calculations indicate leakage error less than 210-6 in delta at frequencies up to 100 kHz
