A TEMPERATURE, HUMIDITY AND PRESSURE INDEPENDENT 1 GW STANDARD RESISTOR: REALIZATION AND PRELIMINARY RESULTS

• Abstract:

  At IEN a temperature, humidity and pressure controlled standard resistor starting from a 1 GW commercially available resistive component was developed; it is particularly suitable as travelling standard for high value resistance measurement inter-comparisons. It was developed inserting the component in a hermetic container in which temperature, relative humidity and pressure are maintained at level of respectively (25 ± 0,01)°C, (7 ± 1)% and 980 hPa. The preliminary results of the measurements with four measurement voltages performed on the standard showed a short-term stability (24 hour) of about 5×10-7 and mid-term stability (1 month) of about 3×10-6.
