DESIGN OF ELECTRICAL POWER DISTRIBUTION SYSTEM FOR A MODERN HOSPITAL

Hospitals are the most complex of building types. Each hospital is comprised of a
wide range of services and functional units. These include diagnostic and treatment
functions, such as clinical laboratories, imaging, emergency rooms, surgery and the
fundamental inpatient care. This diversity is reflected in the breadth and specificity
ofregulations, codes,and oversightthat governhospitalconstruction and operations.
Today's health care facilities, because of their increasing size and complexity, have
become more and more dependent upon safe, adequate, and reliable electrical
systems. Every day new types of sophisticated diagnostic and treatment equipment,
utilizing microprocessors or computers, come on the market. Many of these items
are sensitive to electrical disturbances and some require a very reliable power
source. Invasive medical procedures such as cardiac catheterization have become
routine in today's hospital. Such procedures make electrical safety extremely
important. Moreover, with today's sophisticated lifestyle, it resulted with most ofthe
hospital being centrally air - conditioned in order to provide enhanced comfort to
their patients. This has lead to an increase of the hospital load. However, the major
consideration is that essential services must not be disrupted by any cause.
Therefore, a proper sizing of the electrical equipment is important in order to assure
a continuous supply to the hospital. With the help ofan interactive programming, the
transformer and generator size for any new hospital can be determined.
