Abstract An automated temperature-controlled electrical DC voltage and resistance multiple reference standard (MRS) has been developed by Measurements International (MI) with the scientific support from Istituto Nazionale di Ricerca Metrologica (INRIM). The MRS includes a 10 V, 1 Ω, kΩ standards selectable via switch unit. This setup allows artifact calibration of high-end calibrators multimeters used in low-frequency measurements. two resistors are high-stability MI, while V is based on...
Metrological characterisation of static energy meters under realistic low power quality conditions is a basic requirement for proper grid control and fair billing. The paper reports about new proposed methodology, where the are tested directly recorded at installation sites. waveforms voltages currents sampled using portable instrument; they reproduced in laboratory with phantom generator, bandwidth covering up to 40th harmonic. recording site photovoltaic production facility, having nominal...
A measurement technique to calibrate current clamp meters in ac the range from 100 1500 at 50 Hz has been developed National Institute of Metrological Research (INRIM) addition primary reference systems for calibrations INRIM. This is traceable national standards dc resistance, voltage, and ratio. It based on a standard transformer (CT), 50-mΩ shunt, 61/2-digit digital voltmeter (DVM) that measures voltage shunt inserted conductor, which also meter applied, whose supplied by CT can generate...
Resistance standards with values in the TΩ range play an important role electrical instrumentation. The calibration of such is, thus, a service offered by many metrology institutes. techniques used to measure very high resistance differ quite substantially from applied lower ranges. For this reason, EURAMET technical committee for electricity and magnetism decided 2008 organise first time supplementary comparison at 1 100 based on well characterized travelling standards.
In the framework of preparation National Institute Metrological Research (INRIM) to its participation at “Supplementary Comparison EURAMET.EM-S32 Resistance Standards 1 TΩ and 100 TΩ,” an evaluation two measurement techniques for high resistance measurements INRIM has been made. The first method, working between 10 MΩ TΩ, is based on a digital multimeter dc voltage (dcv) calibrator, second, up modified Wheatstone bridge with programmable dcv calibrators in arms electrometer as null detector....
The capacitance-charging method is a well-established and handy technique for the generation of dc current in 100 pA range or lower. This involves capacitance standard sampling voltmeter, highly stable devices easy to calibrate, it robust insensitive voltage burden instrument being calibrated. In this paper, we propose extender amplifier, which can be employed as plug-in component existing calibration setups, allows currents 1 nA range. has been Istituto Nazionale di Ricerca Metrologica...
At the National Institute of Metrological Research (INRIM) an evaluation a commercial dual source high resistance bridge has been performed.Its two main measurement modes (single measurements and multiple measurements) have investigated.The best settle time 10:1 ratio estimated to be about three times constant circuit involving resistors.This constant, in turn, depends on highest value resistor.By means mathematical estimators, suitable numbers readings detector established order minimize...

Measurement comparisons or inter-laboratory (ILCs) are the main tool to establish measurements' compatibility between different laboratories measurement methods. Therefore, they a mean equivalence of national standards maintained at National Institutes (NMI), correctness traceability transfer from NMIs secondary calibration laboratories, their accreditation processes and suitability operators' competence equipment. ILCs' role is then strategic importance as lay top chain representing system...
