Abstract :
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. Calculations indicate leakage error less than 2*10-6 at frequencies up to 100 kHz. Measured values show that error contributions are less than 1*10-6 at 100 kHz, which is well below the predicted value
