Automatic Calculations
In addition to performing steady, dynamic and short-circuit analysis
LineAmps provides automatic line ampacity calculations at user
specified intervals which may vary between hourly or half hourly
calculations of steady state ampacity under normal and emergency
conditions or time to reach critical temperature calculations that
are performed more frequently in the order of seconds.
Automatic Ampacity
Steady state ampacity calculations for normal and emergency
conditions are updated automatically every hour or at any other user
specified time interval by collecting latest weather data
automatically from the web. An example of automatic steady state
ampacity calculations and the latest weather data acquired from the
web are shown below.
Time To Reach Critical Temperature
When transmission lines are operating at high level of currents it
is important for line operators to know not only the current
temperature of the conductor under current weather conditions but
also future evolution of conductor temperature and the time
remaining to reach maximum permissible temperature of the line which
we call the critical temperature. In other words, the operator is
interested to know how long will it take for conductor to reach
maximum temperature at the present level of current passing through
the conductor. LineAmps provides this information by continuously
updating present and future conductor temperature calculations by
acquiring latest weather information from the web or specified
weather stations and by obtaining actual level of line current input
from utility scada system.
