Compared to 200V AC systems, 400V AC systems are deployed for distribution circuits in stations with especially large loads to suppress voltage drops and reduce distribution loss, to efficiently power elevators
The disaster showed that--more than an inconvenience--losing power is life threatening to those who need electricity to power elevators
, mobility devices, medical equipment, and refrigeration for medicine.
Most generators are considered inadequate to power elevators
, air-conditioning, room lights, and complex life-support equipment.
Today, three generations of Magnetek Ac drives and digital field regulators, and thousands of the Company's analog and digital Dc direct drives power elevators
on six continents.
The building is equipped with emergency generators to power elevators
, emergency lighting and fire alarms, but never lost power.
Another potential application researched by ICI is using the technology to power elevators
using fire hose/suppression water pressure, Huffman said.
The energy-saving motor device to be purchased by Montgomery was developed by and includes PEC's proprietary technology, and is effective in reducing energy consumption in industrial motors, including motors which power elevators
