Article Abstract:
Bust duct as a method of distributing electricity offers advantages in flexibility over other techniques. They are rugged, versatile and compact devices ranging in size from 60 amperes to 5,000 amperes, 120 volts to 15,000 volts, single-phase or three-phase, that can be used as either feeder or plug-in units that can also vary in length. However, the device, which is used in offices, laboratories, data centers and warehouses, also has disadvantages that include susceptibility to water damage and short-circuit problems.

Real-time savings
Article Abstract:
The designers and owners of heating, ventilation, air-conditioning (HVAC) systems should employ real-time pricing (RTP) approach in the selection and design of chiller plants and controls. Integrated system design, which combines various chiller types based on their specific purposes, delivers a overall chiller plant that taps the advantages of each separate chillers for flexbile, real-time exchange of chilled waters among the chillers. The system offers overall reductions in energy consumption and emission.

Climbing the voltage ladder
Article Abstract:
The load densities of manufacturing facilities have significantly decreased over the past decades. The higher load densities demand higher voltage distribution systems that can effectively maintain the power levels required by modern facilities. With the increase in load-demand density, manufacturing facilities should consider 34.5 kva as a viable distribution facilities. The voltage distribution requirements of general manufacturing plants, microelectronics facilities, and steel mills are discussed.
