Reducing energy consumption frees up electrical system capacity

The author analyzes how capacitive power factor correction can increase the existing system capacity, increase system loadability, increase power factor, and reduce both voltage drop and I/sup 2/R energy losses on the line in the form of heat. This last item alone marginally decreases the air conditioning load, saves energy, and increases electrical distribution equipment life, because for every 10 degrees drop in temperature, the lifespan of any electrical device is doubled. He then considers how energy-efficient electric motor technology contributes to minimizing energy consumption and building operating costs. He finally considers the use of solid-state motor starters, which save money by reducing life-cycle costs.<
