Low Frequency Current

Traceability of thermal current converters covering the current range from 1 mA to 20 A has been established to the primary standard of LF current in the frequency range 10 Hz to 10 kHz (Bank of multijunction thermal converter, uncertainty + 20 ppm at 5mA).

The traceability of LF voltage & current has been established by assigning AC-DC transfer difference and these measurement systems have been automated which help us in faster and accurate measurements. The block diagram for these measurements has been shown below.
