  • Sampling Current Ratio Measurement System for Calibration of Current Transducers up to 10 kA With$5\cdot 10^{\mathrm {-6}}$Uncertainty

    A sampling current ratio measurement system has been developed, tested, and validated for the accurate complex ratio measurement of ac current transducers. Calibrations can be performed for primary currents up to 10 kA with typical expanded uncertainties of 5 · 10-6in magnitude and 5 μrad in phase (k = 2). A unique property of the system is the use of digitizers for sampling of the secondary current signals and step-down transformers with a large number of current ratios. Therefore, the system does not require the current transducer under test to be a current transformer having a nominal ratio equal to the reference current transformer. Furthermore, it allows for the accurate calibration of a large variety of different current transformers and other types of current transducers. A bilateral comparison between VSL and NRC confirms the stated uncertainty.

  • Accurate High Direct Current Measurements for Industry

    Calibration of high dc current transformers, dc ammeters, and dc current range extenders can be carried out simply using a high quality dc current transformer, an uncalibrated high current source and a calibrated low current source. The method, called the Current Reference Step Method, utilizes a buildup technique that exploits the ability that a de current transformer possesses to accurately sum the currents through its window with excellent differential linearity. Uncertainties of several parts per million in the applied high current can be achieved.

  • Phase Current-Balance Control Using DC-Link Current Sensor for Multiphase Converters With Discontinuous Current Mode Considered

    This paper presents a new phase current-balance control method of unbalanced phase currents in multiphase converters. The phase current reconstruction process, in which the sampled dc-link current from a dc-link current sensor is used to reconstruct the phase currents, is comprehensively investigated, taking account of both the region of duty ratio and the operating mode of the continuous current mode (CCM) and discontinuous current mode (DCM). DCM operation reveals that the phase current reconstruction cannot coincide with the average value of the respective phase current. Eventually, it is confirmed that this proposed balance control based on a circular chain control makes it possible to establish an exact current sharing among the phase currents all over the operating condition including the DCM. The actual phase currents do not show any distorted waveforms due to the multisamplings of dc-link current that do not provoke any extra switching of the converter switches at all. The validity and effectiveness of the proposed phase current-balance control are illustrated through the experimental results.

  • A Three-Phase Current Reconstruction Strategy With Online Current Offset Compensation Using a Single Current Sensor

    This paper proposes a three-phase current reconstruction technique with an online current offset compensation function for three-phase inverter applications utilizing only a single current sensor. In the proposed current sensing method, a phase current and a branch current are simultaneously measured twice in a switching period by using a single current sensor. After that, the current reconstruction algorithm is applied to obtain the three- phase current information. Compared to previous single current sensor strategies, in the proposed method, the sensor output is regularly sampled, and the dead zone is located near the boundary of the voltage vector space instead of near the origin and the borders of each sector. This boundary- neighbored dead zone makes the proposed method more attractive in extremely low modulation index cases because it avoids periodical dead zones which have been an issue in the existing methods. Moreover, the online compensation method for a current measurement offset makes it possible to achieve purely balanced three-phase current control without an offset component. The effectiveness of the proposed method has been verified through simulations and experiments by measuring and reconstructing three-phase currents under various conditions.

  • Calibration of an instrument current transformer at a ratio of 20 kA/5 A

    This paper presents two methods for determining the ratio error and phase displacement of an instrument current transformer (ICT) with transformation ratio 20 kA/5 A. In the first case, the primary conductor passed by a current 20 kA placed in the centre of the toroid is replaced by a current loop with 10 turns placed in the centre of the toroid. In the second case, the conductor is replaced by 10 turns uniformly distributed along the circumference of the toroid. The primary current 2 kA is measured in both cases using a toroidal current comparator, and the secondary current difference is evaluated by means of an ICT error measurement system.

  • Development of user panel for Polarization and Depolarization Current (PDC) measurement analysis of High Voltage (HV) machine insulation system

    Insulation system is the backbone in any HV machine and as well as power system. However, degradation that always happens in the insulation system will reduce the lifespan of the machine. Thus, condition monitoring of the insulation system is highly recommended in order to maintain the reliability and efficiency of the machine during operation. Polarization and Depolarization Current (PDC) measurement is one of the time domain condition monitoring that been acknowledge by the researchers around the globe. This predictive maintenance with the aid of online monitoring provides an indication of the machine's condition. The development of measurement technologies and data analysis techniques using computational methods give an advantage in saving time and improve safety. This paper presents the user panel that had been developed for the application of PDC diagnostic methods. Through this panel the conductivity level based on PDC measurement on the machine insulation system can be analyze and monitored. The developed user- friendly panel enable user to run the recorded PDC data to evaluate the performance of the insulator in term of its conductivity. It was found that the conductivity level of the insulation material is related to its PDC curves. The system developed was found successfully helping user to do analysis on PDC data by giving the PDC pattern and conductivity of the tested insulator.

  • A nonlinear model for the estimation of the primary current in current transformers

    The measurement of the current in industrial electrical devices is often carried out by resorting to the use of current transformers. The reliability of these devices is compromised when the measured current is higher than the nominal value, due to the saturation and hysteresis effects of the magnetic core. In this paper, a nonlinear model of the current transformer is identified by means of a separable least squares technique. This model is successfully employed for the estimation of the primary current starting from experimental measures of the distorted current.

  • Design of HV switching for polarization & depolarization current measurement

    The method of assessing the insulation condition in high voltage (HV) electrical equipments can never be overemphasized. Over the years, several method of assessing the insulation condition have been researched & used by many researchers. One of these methods is using the dielectric response of the materials to determine the Polarization and Depolarization Current (PDC). PDC is a non-destructive assessment method that combines a sequence of switching operations & current measurement for time domain response. In this paper, the HV switching sequence for a PDC assessment was designed & built to fulfill the PDC assessment basic theory. The switch was applied on three materials used in HV insulation to determine their polarization current (ip) & depolarization current (id). Test duration for both ip & id were 10000 seconds and the test results are presented as a current pattern. The current pattern is consistent with the theoretical current wave PDC pattern from literatures thereby confirming the validity of the built switching device.

    This paper presents two methods for determining the ratio error and the phase displacement of a protective current transformer (PCT) with a transformation ratio of 10 kA/1 A and a measuring current transformer (MCT) with a transformation ratio of 20 kA/5 A. The primary conductor passed by a current (10 or 20 kA) placed in the center of the toroid is replaced by a current loop with ten turns placed in the center of the toroid. In the second case, the conductor is replaced by ten turns uniformly distributed along the circumference of the toroid. The primary current (2 or 1 kA) is measured in both cases using a toroidal current comparator, and the secondary current difference is evaluated by means of a current transformer (CT) error measurement system. The errors were also measured using a CT analyzer.
