Current-carrying capability

The instmments discussed above (and many of the others which follow) act in response to the system voltage and/or current. In most cases, the values of these two parameters are very high, which presents problems in the design of the insulation and current-carrying capabilities of the instmment. In these instances, the instmment is supplied with a known fraction of the measured quantity using a voltage transformer or a current transformer, as appropriate. 

Twin planes play an important role in decreasing the current-carrying capability of the compounds, and they make device fabrication difficult. 

BiChlor contains mesh electrodes, the design of which has been carefully selected to have the most beneficial combination of gas and liquor transport, membrane support and high current-carrying capability. 

The one-meter-long conductor, based on a bismuth-strontium-calcium-copper oxide superconductor, carries over 2300 amps of direct current at liquid nitrogen temperatures (77 K). This is more than twice the current-carrying capability of conventional copper cables. 

Figure 33 The tip of a carbon nanotube fiber after it has been dipped in liquid mercury. This tip and similar ones have been used to demonstrate the quantization and current carrying capabilities of carbon nanotubes.

The kinetics are not very sensitive to the dectrolyte so the choice is laigdy dependent on safety, toxicity, and cost. The rdativdy slow kinetics of the system has necessitated the use of thin electrodes in order to obtain sufficient current carrying capability and these cells are designed as coin cells (Fig. 23a) or as jelly rolls (Fig. 23b) with alternating anode, separator, cathode, and another separator layer. These 3-V batteries are made in sizes not used for aqueous 1.5-V cells to help prevent their insertion in circuits designed for 1.5 V.

Because of their intrinsically high aspect raho, their high current-carrying capability, and their inertness to sputtering, CNTs have been one of the most intensely researched materials for cold cathode applications. Here we have reported some of the more prominent examples many more will surely follow in the near future. 

The commonly used D-subminiature connectors are available in 9,15, 25 and 37 way versions with each pin typically having a 1 A current carrying capability and a dielectric withstand voltage of... 

Two types of sonar projectors are shown in Fig. 3.43. The Tompilz projector uses a stack of longitudinally poled piezoelectric slabs. The slabs are doughnut shaped so that a center bolt can be used to connect the head mass to the tail mass and prestress the multilayer ceramic stack. The slabs typically are metalhzed with thick-film fired-on metals, with thicker metal shims separating slabs for better current-carrying capability. The multilayer stack is electrically connected in parallel.
