Analysis of a national low dc resistance inter-laboratories comparison
16th International Congress of Metrology, 2013
In this paper the description of an inter-laboratories comparison between the National Institute of Metrological Research (INRIM) and nineteen Italian Secondary Calibration Electrical Laboratories, is given along with its main results in graphical way. The transportable standards were three Tinsley four terminal standard resistors to be calibrated in oil respectively at 5 A and 20 A (1 mΩ), 1 A and 5 A (10 mΩ), 0.1 A and 1 A (100 mΩ). The comparison results were satisfactory, except only in a case of a Laboratory for which these measurements were outside its accreditation fields.

Analysis of a National Inter-Laboratory Comparison of High DC Resistance at 10 Mω and 1 Gω Level
Metrology and Measurement Systems
A national comparison of dc resistance at 10 Mȍ and 1Gȍ level was organized by the Electromagnetic Division of National Institute of Metrological Research (INRIM, Italy) and piloted by the same Division. This comparison took place between January and April of 2008 with the participation of 8 secondary Laboratories accredited by the Italian Accreditation of Calibration Laboratories Service (SIT). The travelling package included a wirewound 10 Mȍ standard and a thick film-type 1 Gȍ standard in a wooden anti-shock container designed by INRIM. The obtained results indicate that the differences at 10 Mȍ and 1 Gȍ between each laboratory's value and its reference value are all within the expanded relative uncertainties of these differences.
Measurement setup to characterize electrical standards
19th International Congress of Metrology (CIM2019), 2019
At the National Institute of Metrological Research (INRIM) a measuring setup able to vary, accurately and in a selective way, the temperature, humidity and pressure to detect eventual hysteretic phenomena and to evaluate their effects on electrical standards as high precision standard resistors and Zener-diode based DC Voltage standards. Main element of the setup is a pressure-tight case housing the standards and acting the stresses due to the desired parameters. By means of pressure-tight-connectors, the standards under test are connected to the measuring instruments, while the climatic conditions are acquired through inner and external sensors. Humidity is controlled by means of two conditioning containers filled respectively with water and silica-gel, which regulate the air-moisture percentage the case in a range of 10-90%. A pumping system establishes the pressure in the case from 600 hPa to 1400 hPa. The characterization vs. humidity and pressure is made at constant temperature...
The ampere and electrical standards
Journal of Research of the National Institute of Standards and Technology, 2001
This paper describes some of the major contributions to metrology and physics made by the NIST Electricity Division, which has existed since 1901. It was one of the six original divisions of the National Bureau of Standards. The Electricity Division provides dc and low-frequency calibrations for industrial, scientific, and research organizations, and conducts research on topics related to electrical metrology and fundamental constants. The early work of the Electricity Division staff included the development of precision standards, such as Rosa and Thomas standard resistors and the ac-dc thermal converter. Research contributions helped define the early international system of measurement units and bring about the transition to absolute units based on fundamental principles and physical and dimensional measurements.

Metrological management of the high dc resistance scale at INRIM
Measurement, 2009
In the framework of the revision of the high dc resistance scale from 10 kX to 1 TX at National Institute of Metrological Research (INRIM) a measurement method for calibration of high value resistors based on the use of a digital multimeter (DMM) and of a dc voltage calibrator (DCVC) was projected, developed and characterized. A method based on the Hamon scaling technique was revised and extended to 1 GX. Two other methods, based respectively on a modified Wheatstone bridge and on a current comparator bridge, were implemented. A new 100 MX step Hamon standard, a humidity generator to characterize high value resistors vs. relative humidity and a scanner for high resistances were developed and characterized. The relative 2r best measurement capabilities, obtained in the range 10 kX Ä 1 TX at INRIM with all these methods, span from 2.0 Â 10 À7 of the 10 kX standard resistor at the measurement voltage of 10 V to 1.0 Â 10 À3 of the 1 TX standard resistor at a voltage of 100 V. The relative standard uncertainties of the utilized methods at INRIM are summarized.

In this work the peak kilovoltage (kVp), practical peak voltage (PPV) and air kerma rate were measured with the noninvasive meters Radcal Accu-kV s Diagnostic Sensor TM model 40 Â 12-W, and PTW Diavolt. The results were compared in order to ensure the quality control, compare the meters and establish the new quantity PPV, at the Calibration Laboratory of IPEN. These tests were performed using the standard diagnostic radiology quality beam RQR5, and the results are in good agreement.
Challenges on the measuring and testing techniques for UHV AC and DC equipment
After an introduction of the actual IEC Publication concerning high voltage test and measuring techniques with the relation between the lightning and switching impulse voltage to the highest voltage for equipment (AC or DC) the generation and measurement of the different types of test voltages are described. The required AC test voltages in the range of 1200 to 1800 kV could be generated by transformer cascades or by resonance test systems, where the resonance conditions could be reached by variable inductance for a fixed frequency or by variable frequency for a fixed inductance. AC measurements are combined with partial discharge and dielectric measurements and therefore suitable coupling and standard capacitors are required. Switching impulse voltages in the range of 1800 to 2400 kV and lightning impulses in the range of 2800 – 3500 are generated with Marx generators. Due to the large test circuits for UHV apparatus and the limited space in the test field the electrical field stre...

Continuous monitoring of power grid aimed at assuring compliance of power quality in-dexes to standard requirements, calls for a wide range of instruments, each devoted to a different meas-urement. Metrological confirmation of the whole set of devices and instruments turns out to be a complex task – because of the variety of characteristics to be tested – that requires time to be com-pleted which eventually determines high costs, not to mention that during confirmation activities in-struments cannot be used. The purpose of the laboratory presented is to provide a complete set of con-firmation services through local branches distributed over the territory. A central laboratory plans and supervises activities which are then delegated to peripheral labs employing travelling standards to per-form confirmation directly at client's side thus reducing sensibly times of off-line operations. Experi-mental results from two different kind of measurements that require fast acquisition in on...
