Presentation: Applying Steady-State Cable Temperature Calculations for Safe Cable Operation
Establishing the Current-Carrying Capacity (Ampacity) of underground buried cables plays a vital role when figuring out the maximum power which the cable system can transmit. Equally important is calculating an optimal ampacity in order to operate the cables below their maximum temperature limit. If the temperature exceeds the maximum allowable limit, the reliability and life expectancy of the cable will be reduced. Manufacturers typically publish cable ampacity values at very specific conditions that rarely match actual practice. The Steady-State Cable Temperature calculation determines the operating temperature of cable conductors in a raceway system under a specified loading condition. The calculation is based on the NEC accepted Neher-McGrath approach, which employs a thermal circuit model to represent heat flow situations. We will review hand calculations and also the use of power systems analysis software for these calculations.
