Simulation of power cable ohm heat by using labview

Even it is necessary to consider the ohm heat of cable conductor for the evaluation of cable aging, temperature measurement of cable conductor for the evaluation of cable aging, temperature measurement of cable conductor is impractical due to untouchable condition of cable conductor which is surrounded by insulation and jacket. We have studied the way how to get the ohm heat of conductor by measuring the surface temperature of cable jacket. We verified that jacket temperature can be controlled under the 10% error limit by applying the PI control in LabView program. The relation between surface temperature of jacket and ohm heat of conductor can be predicted after this type of experiment. This study show that the ohm heat can be delivered from temperature monitoring of jacket surface
