Electrical Power Studies
APT electrical power studies team is headed by high qualified engineers that
have extensive experience in these studies and in solving problems related to
these studies to insure safe, reliable and cost efficient operation. This study
is performed by using special computer hardware and software to perform the
analysis of power system studies. The computer model enables us to readily
perform complex calculations and to evaluate the performance of the system by
simulation the overall client power system. APT has the expert engineers to
perform the following studies:
Determine the short-circuit current available at
each component of the electrical system and the ability of the component to
withstand and/or interrupt the current.
Determine protective device characteristics,
settings, or sizes which provide a balance between equipment protection and
selective device operation that is optimum for the electrical system.
Determine active and reactive power, voltage,
current, and power factor throughout the electrical system. Provide an analysis
of all possible operating scenarios which will be or have been influenced by the
proposed or completed additions or changes to the subject system.
Electrical arc flash and shock hazards have been
recognized as particularly dangerous and fairly frequent occurrences that put
the lives and health of electrical workers at significant risk.
Arc Flash is the result of a rapid release of
energy due to an arcing fault between phase to phase, or phase to ground. The
air is working as a conductor during the arc. The arc flash study determines the
worst case arc-flash hazards and associated incident energy conditions.
