While a fault occurs for some reason, at that time the repairing process related to that particular cable is difficult due to not knowing the exact location of the cable fault. The proposed system is to find the exact location of the fault.

[1385]. ANALYSIS OF ELECTRICAL LOAD BEHAVIOUR OF 100KVA ON SAVE LIFE FOUNDATION HOSPITAL: When a disturbance occurs in a power system, the value of load power will change in response to the voltage and frequency changes. Step changes in power generation, for example, will induce speed changes in the system frequency and this induces speed changes in any induction motors or other dynamic loads present in the load, and these speed changes will be seen as power changes to the load. Dynamic loads consume 60-70% of the energy from the power system. It is important to have good knowledge about Dynamic loads, because these type of loads draw large reactive currents that can slow voltage recovery after a fault. In this paper the effect of frequency changes (f) on a various electrical loads real (P) and reactive (Q) power changes have been modeled. Among the parameters of different electrical loads, the behavior is largely characterized by active power (P) and the reactive power (Q). The model of electrical loads in these frequency and power relations that has been developed can be used to estimate P and Q... READ AND DOWNLOAD

[1412]. THE EFFECT OF FRITION ON SURFACE FINISHING DURING ORTHOGONAL CUTTING MACHINING: The generation of residual stresses in orthogonal machining is analysed by using an Arbitrary Lagrangian Eulerian (ALE) finite element approach. It is shown that a substantial level of tensile residual stresses can be obtained in the vicinity of the machined surface without any contribution of thermal effects. This motivates the development of a parametric study to analyse the effects of the thermomechanical coupling parameters on residual stresses. The roles of thermal expansion, of thermal softening and of the Taylor–Quinney coefficient (controlling the heat generated by plastic flow) are considered separately. The influence of friction is also analysed by assuming dry cutting conditions and a Coulomb friction law. The friction coefficient has a complex effect by controlling heat generation (frictional heating) along the tool rake and clearance faces and the propensity for the chip to stick to the tool. Geometrical effects such as the tool rake angle and the tool edge radius are also discussed... READ AND DOWNLOAD
