The power then travels 6000 feet through number 2/0, 15 kV, mine power feeder cable to an underground power center. The power center has a secondary voltage of 1040 volts and is rated 1350 kVA with 5.0% impedance. Power then travels 850 feet through number 2/0, 2 kV, shielded trailing cable to a continuous miner.

Calculate the difference in height required to provide the energy input in Example 1. Energy requirement is provided from potential energy. Power = energy/time. Power requirements = mass/s x g x h = 46.3 kg/s x 9.8 ms-2 x h = 46.3 W . Height required, therefore = 1/9.8 = 0.102m, or about 100 mm. Example 5
