“…Hence HTS cable distribution network cannot realize energy-saving advantages when scheme 2 is used to renovate the distribution network in the selected region, and this result is similar to the result of scheme 1. (11), (13), and (15), the relation curves between the current flowing through the conventional cable and the power consumption coefficient of the cryocooler can be obtained and shown in figure 3. The area above the curve is the area where the energy-saving length of the HTS cable exists, namely when the length of HTS cable is greater than a certain critical length of energy saving, HTS cable can show energy-saving advantages in this area.…”

High Temperature Superconducting (HTS) cables have numerous advantages in comparison with conventional power cables, such as high power density and low power losses, so they have great potential in enhancing the transmission capacity and improving the quality of power grids. In this work, we studied various cases to evaluate the feasibility of replacing conventional cables with HTS cables in metropolitan distribution networks. These cases represent three principal strategies. The first, HTS cables are applied at the same or lower voltage levels with the same transmission capacity, named as "equal capacity replacement". The second, considering the increasing power demands we demonstrate how HTS cables can benefit the power grids with expanded capacity (expanded capacity replacement). The third, we consider the case of unequal routes from the perspective of saving land resources (unequal routing replacement). In this paper, we introduce the methods and results of this study and give some preliminary conclusive remarks.

“…High Temperature Superconducting (HTS) cables operating at Liquid Nitrogen (LN 2 ) temperature (77 K) offers zero DC resistance and can be used in transmitting bulk power with reduced transmission losses 1-3 . However, during the operation of HTS cables, to retain the superconductivity, it is must to maintain the HTS cable below its three critical parameters that is, critical temperature (T c ), critical current (I c ) and critical magnetic field intensity (H c ) [4][5][6][7] . In HTS cables, the parameter H c is usually not significant until and unless it is subjected to the external high magnetic field intensity.…”

High Temperature Superconductor (HTS) based power cable is a technological marvel which can transmit bulk power over large distances without any joule heating as compared to a conventional copper cable, owing to its zero DC resistance in superconducting state. However, to maintain this superconducting state, the cable must be at a temperature below its critical temperature under self-field. Commonly used HTS material includes BSCCO (Tc = 110 K) and YBCO (Tc = 93 K) and thus, requires cryogenic liquid nitrogen (77 K) for attaining superconductivity. Further, the voltage drops across the various joints such as joint box and current leads in the termination unit must be monitored to ensure optimal operation of the cable. This demands for sophisticated instrumentation operating under extreme low cryogenic temperatures for safe operation, performance monitoring, cryogenic measurements, and control of the HTS power cable cryogenic process. This paper presents the instrumentation scheme followed for testing India’s first 6-meter HTS power cable. The instrumentation scheme involves housing of the various temperature sensors and location of voltage tapping, current measurement, cryogen flow measurements, operation of control valves, operation and measurement of high vacuum system, stray field measurement, insulation resistance measurement and dielectric measurements for cable are the important parameters for the successful operation of HTS power cable. To perform data logging NI-DAQ and LabVIEW software was used to develop in-house Supervisory Control and Data Acquisition (SCADA) system. This paper discusses intrinsic aspects of complete instrumentation and developed SCADA system for HTS power cable.

Triaxial HTS AC power cables, that incorporates three HTS phases wound around a single core within a single cable is considering the optimal solution for low and medium voltages. Such a design permits to save expensive HTS conductor and to increase the power density transmitted. It is difficult to increase the transmission capacity of a triaxial cable by increasing its operating voltage and therefore, insulation thickness between phases. The other way is to increase the operation current by using a multilayer structure in each phase of the triaxial cable. This task demands a complicated optimization analysis and a precise manufacturing technology. Following our previous studies, we developed and tested the triaxial cable prototype with two layers per phase made of ReBCO wire. The optimal parameters of the cable (twist pitch, diameters of phases, etc.) have been determined using the numerical simulation methods developed. DC and AC tests of the cable has been performed. In the result, the feasibility to provide a uniform current distribution in a triaxial cable, each phase of which consists of two layers, has been demonstrated. With an outer diameter of ~24 mm only, this is the most compact triaxial HTS power cable manufactured and tested up to date with currents up to 4 kA per phase. The anticipated power transfer with three phases opf this cable can be as large as ~34 MW. 
