“…During 1998-2003, a 120 meter demonstration cable circuit was designed and installed between the 24 kV distribution bus and a 120 kV-24 kV transformer at Detroit Edison's Frisbie substation. Impressively, the HTS cables in which copper was replaced with Ag-sheathed Bi 2 Ca 2 Sr 2 Cu 3 O x superconducting tapes wrapped around a flexible former were able to carry triple the power compared to the existing copper cables whilst weighing 30 % of the original weight [46,47]. Although the system incorporating cables, accessories, a refrigeration system and control instrumentation was never put in operation because of leaks in the cryostat, the project significantly advanced the state of the art in the design and implementation of HTS cable systems and proved to be enlightening for subsequent efforts in this engineering field.…”

The accidental discovery of mercury's zero resistance at temperatures lower than 4.2 K which took place in 1911 by the Dutch physicist Heike Kamerlingh Onnes in his laboratory at the University of Leiden, appeared to be one of the greatest breakthroughs of physics of all time. It has led to the creation of an entirely new field within physics called superconductivity; this attracted many of the finest minds in physics whose work in this area produced no less than six Nobel Prizes to date. Zero resistance, together with the expulsion of magnetic fields which was discovered many years later, are the two unique and intriguing properties of superconductors which puzzled scientists' brains for a proper theoretical explanation of the observed phenomena. However in 1935, the phenomenological theory proposed by Fritz and Heinz London (known as the London theory) was the first success in the field, which was followed in the 1950s by another phenomenological theory put forward by Vitaly Ginzburg and Lev Landau. Despite this, a satisfactory microscopic theory for superconductivity had to wait until 1957 when John Bardeen, Leon Cooper and John Robert Schrieffer proposed their theory, whic was nicknamed the BCS theory in their honour. The more recent discovery of the cuprate high temperature superconductors (HTS) in 1986 gave a new momentum to the field and intensified the search for room temperature superconductors which continues to this day. While this quest is under way, and new theories of superconductivity are being developed, physicists, material scientists and engineers are using superconductors to establish new technologies and build machines, devices and tools with unprecedented properties. Today superconductors are widely used in healthcare, particle accelerators, ultrasensitive instrumentation and microwave engineering and they are being developed for use in many other areas as well. In this review, we will trace the history of superconductors and provide a brief overview into some of the recent applications of superconductivity.

“…The configuration of this base sub-model closely matches the existing Citipower's WMTS section of the network with zone substation loading obtained from the company's planning report [11]. In this sub-model, a 2011 load demand has been used to determine the overall load flow and identify stressed or exceeded rating elements in the network.…”

Currently, most of the transmission line infrastructure are being considered for an overhaul due to aging, detrition and overloaded. In light of this, the authors believe it is a good time for investing in a new technology so that the network can truly meet most of the challenges.High Temperature Superconductive (HTS) cable has a unique characteristic of low impedance to current flow. Unlike conventional power cables, HTS cable offers higher power transfer with minimum losses and more compact design of power applications yet better power flow absorption in the networks at the same voltage levels.In attempts to closely study the effect of HTS cable on power networks, several pilot projects have been carried out around the world. Promising results are achieved in terms of cable capacity and reliability. However, the big challenge of this technology is the high cost of superconductive materials in addition to the cost associated with cooling the cable, which is required at its normal operation temperature (-208ºC for present HTS cables). A new cable was developed by Ultera, utilises the cryogenic electrical insulator, together with high-reliable cable cooling technology that aims at a long service life, have significantly reduced the cost of HTS cable technology. The future will witness further reduction in the cost of HTS cable, certainly when industry scale production commences. This paper will present the technology in HTS cable and its anticipated effects on power transmission networks.For the last few decades power transmission for long distance was only possible with extra high voltage. However the transmission network required huge investment in high voltage equipment and switch-gear, yet it came with big electrical transmission losses. Fast growing cities and deregulation of the electrical sector in many countries around the world resulted in overwhelming demand for more power [1]. So far, the focus of the Australian electricity market has been narrowed onto the generation part of the power network, directing much of power investment into the new way of generation and renewable energy technology. This leaves the transmission part of the network with the burden of ageing and overloading to face reliability challenges in spite of this HTS cables have the potential for increasing power transmission capacity. Therefore, by transferring a larger amount of generated power that normally is lost in conventional power transmission cables, less generation is then required for the existing load [2]. Subsequent section of this paper describes in detail the obtained results from the load flow analysis performed on the hybrid sub-model, where four lengths This work was supported in part by Energy Safe Victoria.
