The Equipment Evaluation Study module compares protective device ratings with
short-circuit calculations. The program also checks for missing input data and
compares continuous ratings to calculated design and operating conditions. Equipment
that fails the evaluation are reported in table form and color-coded by the one-line
diagrams. As with all PTW study modules, Equipment Evaluation uses the same project
database, integrating all balanced and unbalanced/single-phase study modules, and
allowing you to examine existing projects without additional input requirements.
Benefits:
Helps you design safer and more cost effective power
systems.
Helps you design safer and more cost effective power
systems.
Reduces mistakes by systematically comparing continuous
and short circuit currents to equipment ratings.
Saves you time by making all de-rating adjustments
and by summarizing all of the necessary data into
a single easy-to-read table.
Saves you time by flagging the equipment that are
in the marginal range or failed in the rating checks.
Saves you time by running all related studies in one
click.
Increases flexibility by allowing user defined criteria
for pass/marginal/fail.
Increases flexibility by evaluating short circuit
ratings, continuous ratings, or both.
Communicate designs more effectively with professional
reports and annotated one-line diagrams.
Interface Options:
Intuitive graphical interface enables navigation of
device type and generation of study results and reports.
Study Results can be printed in a concise Report format
or exported to an Excel-compatible spreadsheet.
Choose from Equipment Evaluation Reports and Datablocks
or graphically identify equipment that fails the evaluation
in a color-coded one line diagram.
Clear and concise reporting of all equipment in a
system enables easy diagnosis of potential problems.
Sort results by device type, status, bus, voltage,
ampacity, and more.
Input data evaluation and reporting to identify missing
data or errors in input data.
Study Options:
Continuous rating checks includes cables, transformers,
transmission lines, buses, generators, protective
devices, panels, and protective devices on individual
panel circuits.
Short circuit interrupting and withstand rating checks
for protective devices, buses and schedules.
Choose between balanced and unbalanced study results,
protection and non-protection device types.
Choose between bus or branch fault study results from
ANSI, IEC, or comprehensive fault analysis methods
for evaluation.
Equipment evaluations can be performed based upon
used-defined limits or system defaults.
