Power electronics have been playing a big role in many fields of our daily lives. However, as has been well known, at least among high voltage electrical insulation engineers for these two decades, this situation brings about a drastic increase in the risk of partial discharges (PDs). That is, compared with ac voltages with sinusoidal wave shapes at frequencies of 50 or 60 Hz, voltages fed from or

When a material undergoes a phase change such as a solid turning into a liquid, generally energy is absorbed by the material in order to change from a solid to a liquid. This energy absorption, at the phase change point, can be utilized to enhance a heat sink capacity during transient events to control the temperature rise in an electronic component. Phase-change materials (PCM) can be incorporated

The COVID-19 pandemic has made it very difficult to provide you an accurate conference schedule. Instead of holding face-to-face meetings at their scheduled time, some conferences have decided to either hold a virtual conference or delay/cancel their meeting. Please check the conference website to receive the most up-to-date information.

In recent decades, the discovery and the development of new materials, mainly polymer-based, has opened new perspectives for the improvement of extruded high-voltage cables for transmission lines. The implementation of new materials in extruded cables, allows both the raising of voltage limitations for currently used insulation materials; and enables longer application life. Extra-High Voltage DC cables

The 2020s are going to be an exciting decade of change in terms of how people interact with the electricity grid. In Australia and New Zealand, the electricity systems are decarbonizing, driven by economics and government policies. New technologies such as rooftop PV, solar, and wind are entering the system. Electrical transport and batteries are expected to become mainstream soon as costs continue

The time has come for us to bid farewell to the Editorship of this Magazine. We have enjoyed contributing to its development for the last two and a half years, but we will be leaving it in capable hands and you will continue to receive interesting and relevant reading.

In Australia, similarly to other countries, the grid was designed and constructed to transport energy from large fossil-fuelled generators to load centers. There has been a very rapid uptake of large renewable generation and their lifecycle costs are continuing to fall. These solar farms are generally located in sparsely populated areas where large packets of land are available. However, the grid infrastructure

Current transformers (CTs) are extensively used in electrical switchyards and substations for metering and protection purposes [1] and are expected to operate properly for at least 30 years [2]. Normally, aging of CTs under service conditions is relatively slow, but they also may fail prematurely due to various reasons, such as design faults, inadequate quality during manufacture, lightning strikes

It is generally recognized that dissolved gas analysis (DGA) is a powerful tool in the diagnosis of insulating liquid filled power equipment. There exist numerous evaluating schemes for the mineral oil filled equipment, nevertheless, the experiences show that a fine tuning and revision of the schemes is required for equipment filled with synthetic esters.

The installation of distribution transformers in environmentally sensitive areas is a growing concern of electric utilities, and everywhere it sees a strong local resistance. Special and costly measures must be taken to address this concern, for example, by reducing the risk of transformer oils being inadvertently released into the environment. To solve this problem, promising natural esters based

The new internet standard 5G offers new possibilities to combine and connect different platforms like artificial intelligence (AI) and the internet of things (IoT) which will influence almost all aspects of people's lives. The connectivity of all these things will revolutionize the way information will be transferred and distributed. In 2025 the amount of connected devices will approach 75 billion

Modern society is supported by various technologies such as AI (artificial intelligence), IoT (internet of things), 5G (fifth generation technology standard for cellular networks), etc. Indispensable key components within these technologies are, of course sensors that detect and monitor various physical, chemical, and biological parameters. To monitor mechanical movements, such as vibration and bending

Sensor and actuator applications have exploded in the last several decades and, along with their associated electronics and information processing systems, they are becoming ubiquitous in modern engineering devices and systems. The marketplace demand is huge and growing rapidly, with the global demand for all sensors predicted to exceed $280 billion by 2023 (BCC Research) and the overall actuator market

Additive manufacturing (AM) is an alternative method for producing parts and can be an economical method even when compared to traditional manufacturing methods, especially for low volume and/or high complexity parts. Over the past decade, process and material advances have greatly improved the quality and robustness of AM parts (also referred to as 3D printing) as well as a greater number of material

This issue is focused on underground cable diagnostics. Therefore, I thought it would be appropriate to review the latest changes occurring in the cable diagnostics business. Underground cables are an important part of electric power transmission and distribution systems. The global market of the HV power cables is estimated to grow to $14 billion during 2020–2024.

This issue of the Magazine presents articles related to cable diagnostics and technology. Two of them, written by authors from Canada and Australia, summarize experiences and research activities on the use of dielectric response spectroscopy for diagnoses of insulation condition in medium voltage cables. The third article presents work performed in the USA on development of superconducting gas insulated

Cables are valuable assets, critical for ensuring the continued reliability of electric power delivery. XLPE cable systems have become increasingly ubiquitous, since their introduction in the 1960s. Improvements in the XLPE manufacturing technology resulted in the advent of tree-retardant XLPE (TRXLPE) type cables in the 1980s. Most of the distribution utilities have already either initiated or completed

Polymeric-insulated cables, especially cross-linked polyethylene (XLPE) cables, are widely used in power system transmission and distribution networks. A cable failure can result in lengthy outages and substantial economic loss to the electrical utilities. One of the primary reasons for cable fault is insulation degradation over the service time. Various onsite electrical, thermal or mechanical stresses

High Temperature Superconducting (HTS) power cables are being developed for a variety of applications including the electrical power grid, electrification of transportation, and high energy physics. The appeal of superconducting technology is its high current density — generally greater than 100 A/mm 2 — compared with conventional copper and aluminum conductors, which generally do not support greater

In many industrialized high voltage applications, polymeric insulators are subjected to high electric field strength. Examples are cables, gas-insulated switchgears (GIS), capacitors and others [1]. The difficulty in the design process of these components is to ensure and predict their long-term reliability, where one among the important aspects is prevention of local degradation phenomena. Applications

Japan was hit by the Great East Japan Earthquake and by the resultant big “tsunami” (big tidal waves) on March 11, 2011. For researchers and engineers in the field of electric power or nuclear engineering in countries other than Japan, the memory of the disaster that occurred in the Fukushima Daiichi (= First) Nuclear Power Plant might have still been more vivid and memorized more strongly than the

To determine the characteristics and likely performance of an electrical insulation system and materials used in electrical systems, strong evaluation methods are required. The DEIS Standards is the vehicle that electrical insulation engineers as well as many researchers in the academic and industrial environment use to evaluate insulation systems.

Operational amplifiers, generally referred to as op-amps, are very versatile electronic components. They are typically used as amplifiers, however, depending on their configuration, they can be used to create many different types of circuits that can be used to perform various functions.
