PTW Equipment
Evaluation Study Module
| 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. Any equipment that fails the evaluation is
reported in tabular form and colour-coded on the SLDs. 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. |
|
|
Reduces mistakes by systematically comparing continuous and short-circuit
currents to equipment ratings. |
|
|
Saves you time by making all de-rating adjustments and by summarising all of the
necessary data into a single easy-to-read table. |
|
|
Saves you time by flagging equipment that is in the marginal range or
failed in the rating checks. |
|
|
Saves you time by running all related studies
at once. |
|
|
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
SLDs. |
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 colour-coded SLD. |
|
|
Clear and concise reporting of all equipment in a system enables easy diagnosis
of potential problems. Sort results by device type, status, bus, voltage,
rating, 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. |
