  • Application of instrument transformers in power quality assessment

    To assess the quality of electricity supply through the power networks it is necessary to use instrument transformers or other devices for measuring voltages and currents of considerable values. In many terminals the quality of electric energy is significantly deteriorated and this result in the occurrence of the conducted disturbances in the primary signal of the instrument transformer which cause deterioration of its metrological characteristics. The main indicators to determine the level of periodic waveforms distortion are RMS and average values, total harmonic distortion (THD), crest and shape factors. Laboratory tests consisted of determining these parameters in the system with and without instrument transformers for pre-defined and repeatable distorted waveforms of instrument transformers primary windings supply voltage. The tests were performed for voltage (1000V / 100V) and current (5A / 5A) transformers. On the basis of comparison between values of designated parameters used in estimation of the power quality, obtained for measurements of the same distorted waveforms, in measuring circuits with and without instrument transformers additional errors caused by their operation is determine. It was found that higher harmonic from disturbance signal in the primary circuits of both voltage and current transformers causes increase of errors during the transfer of the signal basic harmonic (50 Hz). Furthermore, in the case of disturbance signals which frequencies are higher than 50 Hz the decrease in transfer ratio and increase of the higher harmonic phase displacement after transfer by the instrument transformer is noticeable. It must therefore be concluded that during the transfer of distorted signals through the instrument transformers their errors are increased in relation to the value defined for sinusoidal signals which frequency is 50 Hz. This leads to additional error in determining the parameters of voltages and currents used to define the power quality.

  • Experiences with Measurement and Analysis of the Dielectric Response of Instrument Transformers

    This paper describes the specific requirements on measurement and analysis of the dielectric response of oil-paper-insulated, inductive instrument transformers and presents various case studies. Dielectric response testing has been developed decades ago for condition assessment of power transformers. Measurement and analysis of the dielectric response in a wide frequency range provides information about the insulation condition of oil-paper-insulations; that is water content in the solid insulation and oil conductivity. The adaption of this method for instrument transformers requires knowledge about the insulation construction and influence of specific effects. This paper describes the effect of different instrument transformer designs on the dielectric response. It has been found that for voltage transformers with their specific HV insulation design, the measurement and analysis of the dielectric response is of almost no benefit. In contrast to this, for current transformers a model similar to power transformers can be utilized for estimating the insulations aging condition. This is similar for combined voltage and current transformers. Case studies with scrapped instrument transformers and a large number of field measurements underline the findings. The dielectric response (capacitance, losses and dissipation factor) has been measured across a wide frequency range of typically 1000 Hz to about 1 mHz. Lower frequencies are in most cases not necessary due to the absence of large oil gaps. With on-site measurements, a major challenge comes from noise and disturbances of the surrounding substation. Various attempts are discussed to limit the effect of noise. These are special connection techniques, proper guarding, the evaluation of specific criteria in the dielectric response and the application of high measurement voltages. In summary, dielectric response analysis is found valuable for current transformers with oil-paper insulation, but not for voltage transformers. Measurement and analysis still requires the knowledge of an experienced user.

  • Modern insulation condition assessment for instrument transformers

    Instrument transformers in service are exposed to the harming effects of water and ageing. The increasing age is leading to a higher risk of explosions, which can damage surrounding parts and cause high follow-up costs. This paper introduces a new approach to use the dielectric response analysis for condition assessment of instrument transformers. The measurement of the dielectric response in a wide frequency range provides information about the insulation condition and especially for oil-paper/pressboard insulations about the water content in the solid insulation. The measured curve is formed by the superposition of the dielectric response of the cellulosic material and the oil. The curve can be used for the assessment of the insulation condition in various ways. Qualitative comparisons, e.g. between instrument transformers of the same type and age, might give general information which of these is in better condition. The dissipation factor and the capacitance trend can also deliver valuable data. Furthermore the water content in the solid insulation can be assessed using an automatic analysis algorithm. To confirm the validity of this assessment, measurements on several instrument transformers in service were performed. Dielectric response curves and the trend of the capacitances for new and aged instrument transformers with different water contents are discussed. Selected examples presented in this paper show, that the dielectric response is well modeled, the water content can be derived and ageing effects can be observed.

  • Evaluation of optical instrument transformers for on-site calibrations of high voltage measurement systems

    The evaluation of optical instrument transformers for on-site calibrations of high voltage power/energy measurement systems, including synchrophasor systems, at power system voltages up to 245 kV and currents up to 5,000 A will be presented.

  • On-line correction of errors introduced by instrument transformers in transmission-level steady-state waveform measurements

    The successful implementation of a transmission level harmonic measurement system requires accurate and reliable measurement of harmonic voltages and currents. Existing substation instrument transformers are designed for 60 Hz measurements and they have been shown to cause resonance errors in the measurements. In this paper, we propose an on-line error correction method to correct for these resonance errors as well as possible saturation errors. The error correction is formulated as an output tracking problem where the distorted measurements are used along with the experimentally developed transformer model to reconstruct the transformer input. The method is generic, thereby permitting its use with any measurement system that utilizes a transducer with nonideal properties. It is also cost effective since it can be implemented on a personal computer or a digital signal processing chip.
