Calibration Methods for Reproducible and Comparable Electromagnetic Partial Discharge Measurements in Power Transformers Book Review:

The reliability of electrical energy networks depends on the quality and availability of their electrical equipment, e.g., power transformers. Local failures inside their insulation can lead to breakdowns resulting in high outage and penalty costs. To prevent these destructive events, power transformers are tested for partial discharge (PD) activity in a routine test before shipment. Furthermore, PD activity can be evaluated as a diagnostic measurement on-site (on-line or off-line) or be constantly monitored during service using the ultra-high frequency (UHF) method. In this thesis, a calibration procedure is proposed for the UHF method used in power transformers, which is lacking so far. The calibration process is required to ensure both reproducibility and comparability of UHF measurements. Only a calibrated UHF measurement procedure can be deemed reliable and eventually be introduced to supplement in (site-)acceptance tests of power transformers. The proposed calibration method considers two factors: The influence of the UHF sensors' sensitivity and that of the UHF instrument characteristics, including accessories like cables, pre-amplifier, etc. The UHF instruments' influence is corrected by using a defined and invariable test signal as a reference for all recording devices comparable to the calibration method used in IEC 60270 for electrical PD measurement. The sensitivity of the UHF sensor is addressed by a characterization of UHF sensors using the antenna factor (AF) measured in a special reproducible setup, i.e., a GTEM cell. In this thesis, a self-built GTEM cell is presented, which is oil-filled to address the environmental conditions inside a transformer where the sensor will be used. With such a cell, influences on the AF of UHF sensors are investigated, and it is shown that sensor sensitivities measured in an air-filled cell can be corrected to the oil environment. A practical evaluation of the proposed calibration procedure is performed in a laboratory setup on a distribution transformer with different UHF instruments and sensors using artificial PD signals and real high voltage driven PD sources. Finally, this thesis identifies future research topics, which may be needed to improve the proposed UHF calibration procedure for power transformers and the UHF method in general.

Recent Trends in the Condition Monitoring of Transformers Book Review:

Recent Trends in the Condition Monitoring of Transformers reflects the current interest in replacing traditional techniques used in power transformer condition monitoring with non-invasive measures such as polarization/depolarization current measurement, recovery voltage measurement, frequency domain spectroscopy and frequency response analysis. The book stresses the importance of scrutinizing the condition of transformer insulation which may fail under present day conditions of intensive use with the resulting degradation of dielectric properties causing functional failure of the transformer. The text shows the reader how to overcome the key challenges facing today’s maintenance policies, namely: The selection of appropriate techniques for dealing with each type of failure process accounting for the needs of plant owners, plant users and wider society; and Cost-efficiency and durability of effect. Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degeneration into full-blown functional failure. This “on-condition” maintenance means that equipment can be left in service as long as a specified set of performance standards continue to be met, avoiding the costly downtime imposed by routine and perhaps unnecessary maintenance but without risking equally expensive failure. Recent Trends in the Condition Monitoring of Transformers will be of considerable interest to both academic researchers in power systems and to engineers working in the power generation and distribution industry showing how new and more efficient methods of fault diagnosis and condition management can increase transformer efficiency and cut costs.

Quality Confirmation Tests for Power Transformer Insulation Systems Book Review:

This book focuses on oil-paper insulation included in power transformers, especially for EHV and UHV transformers. The importance on insulation ever increased due to a growing voltage rating of transformers. Within the last decades, although research on the transformer insulation and diagnosis methods has advanced a lot, the insulation of HV transformers remained more or less unchanged. The book is divided into five chapters; the first and second chapters explain the basics of oil insulation, while the third chapter focuses on paper insulation. The final two chapters deal with the methods and outcome of testing both techniques. The primary target audience for this book is graduate students and power system engineers.
