Standardized values of current transformers with the rated secondary currents of 5 A and 1 A are defined according to the requirements of analog measuring and relay techniques that were typical for the technology of the last century. The development of microprocessor technics and technology as well as digitalization processes in transmission and distribution sectors of power industry requires rated secondary currents of current transformers of less than 1A. That implies different technical and technology difficulties in manufacturing such transformers as well as its accuracy testing. This paper is contribution to the calibration of current transformers with the rated secondary currents of less than 1A. The paper presents a new, modified differential measurement method that enables the calibration of the current transformers with the rated secondary current of less than 1A using a standard current transformer with the rated secondary current of 5A.

To improve power quality and power system stability, load frequency control (LFC) is introduced. The object of load frequency control has been transformed into a new power system with the participation of renewable energy sources with characteristics such as randomness, intermittentness, and volatility. In the interconnected power system, the control of load frequency plays an important role in the control of actual power, frequency, and link power. This paper mainly constructs a three-region interconnected power system model of wind, solar, thermal, and storage, combines fuzzy control and Proportional-Integral-Derivative (PID) control to build a fuzzy PID controller, uses the performance index time absolute error integral (ITAE) as the objective function, and an improved Sparrow search algorithm is used to optimize the proportional parameters of the fuzzy controller and the initial values of the PID controller, and the frequency deviation and the contact line deviation of the system are controlled in a smaller range.

It simulates real-world scenarios, balancing energy management through hydrogen fuel cells and batteries. The system comprises three blocks: one for fuel cells, one for batteries, and one for propulsion, hydrogen consumption measurement, and motor performance evaluation. Experimental tests validate its effectiveness in replicating urban and exurban cycles, making it an ideal scale model for hybrid vehicles, following the UNI EN 1986–1:1998. It reveals consistent behaviour between engine energy demand, speed variations, and energy storage responses, providing valuable insights for hybrid vehicle development. Moreover, the bench's modularity not only supports diverse system configurations but also serves as an educational tool, inspiring and promoting innovation in sustainable transportation.

This paper introduces a novel measurement method utilizing the Compressed Sensing (CS) technique that enables the real-time estimation of impedance variation in an induction motor coil. Herein, a mathematical model of the proposed measurement method is described, and thereafter the motor coil impedance model and the method's numerical assessment in terms of root-mean-squared error as a main figure-of-merit for method validation are presented. The preliminary results indicate that the proposed measurement method has the potential for sensing motor coil impedance variation with good accuracy. This capability could be further used for non-contact inside motor temperature estimation or for detecting motor faults.

The calibration of non-automatic weighing instruments with a capacity of several tons, such as processing tanks, requires significant efforts and poses safety risks to calibration technicians. In response to these challenges, METTLER TOLEDO has developed a calibration method utilizing hydraulic actuators and force measurements, which has achieved ISO 17025 accreditation in several countries. This article outlines how hydraulic calibration can be aligned with traditional calibration standards, such as EURAMET Calibration Guide 18, and how traceability to the SI unit of mass can be ensured. An approach for calculating measurement uncertainty at calibration is discussed. Calibration results demonstrate high agreement between traditional calibration with test weights and the new hydraulic force calibration.

By means of a symmetric kinematic pair consisting of arc-shaped guide rails and rollers, a self-centring device was designed to achieve self-centring of high-class, large-mass weights during calibration. Achieving self-centring can reduce the influence of the load offset error on the mass comparator accuracy. Experiments were performed to verify the effectiveness of the self-centring device by comparing measurements gathered with and without use of the device. The results showed that the self-centring device reduced the load offset error of the mass comparator and improved the calibration accuracy.

China's first torque standard device was established in 1977, developed by Shanghai Marine Equipment Research Institute, and its measuring range is 3000 N m. In 1987, Shanghai Marine Equipment Research Institute developed two torque standard devices, 30 kN m and 200 N m, and established China's first torque measurement and testing laboratory. Over the next 30 years, Shanghai Marine Equipment Research Institute and Chinese Academy of Metrology have developed 2000 N m automatic torque standard device, 20 kN m air bearing torque standard device, 50 kN·m lever torque standard device, 200 kN·m dead weight torque standard device, 200 kN m reference torque standard device, 100 N m negative step torque standard Device, 600 kN m reference dynamic torque standard device, standard torque wrench calibration device, 1 N·m torque standard device and so on. This paper introduces the principle, classification, structure, core components, range, accuracy and other indicators of China's current torque standard device, as well as the next step of China's torque standard to 5 MN m and 10−8 N·m limit development needs, and finally will establish the full traceability chain of super torque and micro torque standards to meet the needs of China's ships, wind power and other super torque and micro machinery torque traceability.

In this study, an optical system for linking quartz crystal microbalance (QCM) sensed nanograms to laser power has been demonstrated by hybridising a laser power measuring system with a QCM. QCM sensed masses are linked with equivalent masses of the photon radiance force at nanogram level with acceptable differences and/or errors. For laser power at 5.78 mW–85.1 mW, equivalent masses of photon radiance force are 2.78 ng–40.96 ng, respectively. Correspondingly, mass dependent resonant frequency shifts sensed by QCM are 0.88 Hz–10.83 Hz, indicating that QCM sensed mass changes are 3.53 ng–43.32 ng, respectively. Updates and improvement toward the measurement system are still needed to get rid of the small differences and/or errors between photon radiance force equivalent masses and QCM sensed masses. The calibrations of the geometry and optical instrument are necessary for translating this method into traceable applications.
在这项研究中，通过将激光功率测量系统与石英晶体微平衡（QCM）混合，展示了一种将石英晶体微平衡（QCM）感测纳米图与激光功率连接起来的光学系统。QCM感测质量与纳克级光子辐射力的等效质量相关联，具有可接受的差异和/或误差。当激光功率为5.78 mW - 85.1 mW时，光子辐射力的等效质量分别为2.78 ng - 40.96 ng。相应地，QCM感知的质量相关谐振频移为0.88 Hz - 10.83 Hz，表明QCM感知的质量变化分别为3.53 ng - 43.32 ng。为了消除光子辐射力等效质量与QCM传感质量之间的微小差异和误差，测量系统还需要进行更新和改进。为了将该方法转化为可追溯的应用，必须对几何和光学仪器进行校准。

The traditional force measurement chain consists of the force transducer itself, a connection cable, an amplifier module with interface or display to give out the measurement data.
Smart sensors are a combination of all components, meaning the sensing element, the amplifier module and the interface are combined in a single unit. Therefore, the new digital sensors are measurement chains which require some attention concerning the calibration procedure.

Ecologizing education by situating it in the workplace and other environments in which new learning is applied improves outcomes by structuring personal experiences connecting knowledge and its use. Since 2015, an international movement of formal and informal educators, employers, government offices, philanthropists, and community groups have collaborated to ecologize science, technology, engineering, and mathematics (STEM) learning with the aim of facilitating the creation of otherwise unimaginable future technical and career developments. Ecologizing requires coordinating these groups' activities while they operate at differing micro, meso, and macro levels. Ostrom's theory of participatory social ecologies implies a mathematical model of hierarchically complex relations of data, instruments, and theory. The Caliper measurement system structures the STEM learning ecosystems' communications at these three levels with the aim of maximizing evolutionary potentials, doing so by providing processes of natural selection with opportunities for amplifying innovative new forms of sociotechnical life adaptively integrated with their environments.
