Here are just a few reasons how PTW 6.0 can help you:

*UNDO feature is now available in the one-line interface with unlimited steps. Users can now undo component destroy, connect/disconnect, and adjustments on any one-line diagram!

*Indulge yourself in thousands of validated protective devices from manufacturers including GE, Basler, ABB, SEL, Siemens, GE Multilin, Bussmann, and more.

*PTW now creates associated one-lines automatically with your TCC when you use the Go To TCC command. Also, datablocks with study results such as Arc Flash now update dynamically as you manipulate the TCC settings.

*Save time and headaches by utilizing the new ‘Find’ feature that will allow you to search selected components through all your one-line diagrams or TCCs. This feature will auto-zoom to the selected component instantly!

*The Data Visualizer now makes comparing multiple scenarios even easier by listing the scenarios side by side in a spreadsheet, along with a column of the minimum or maximum value right alongside.

*UPS, Dynamic VAR Compensator, Static VAR Compensator, and Power Factor Correction equipment are now available as standard component types. New transformer sub-types automate the modeling of Shell, Core, and Zig-Zag transformers!

*Improve efficiency by using the GoTo feature to take components to any other document. Go from one-line diagrams to the Arc Flash result table to TCCs drawings to the Equipment Evaluation table and back! This feature makes it easier to narrow your data to only what you need to show.

*Arc Flash custom labels can now include user-defined warning label text, head/face, hand/arm, and foot protection for each PPE category. PTW includes the ability to merge, copy, and paste other custom labels to your existing label and preview custom labels before finalization. You can now generate a single label that includes both Arc Flash Bus and Line Side results.

*Ability to plot multiple protection functions of a single device on a TCC drawing.

*New option in “TCC Settings” > “Fault Current” tab to select a Reference Device and use its fault current as the reference for shifting and coordination of the TCCs based on the ratio of the fault current through each device and the referenced device.

*New Template Library stores typical designs of sub-systems with the one-line layout and component data. Companies may create templates and set internal design standard to be used as the building blocks for all projects.

*New “Data State” drop-down list in Component Editor and TCC to identify data entry status including: Incomplete, Estimated, Complete and Verified. Users can query components with "Incomplete" Data State and continue work; or globally change the 'state' of all selected components in the Data Visualizer.

*Generator and synchronous motor fault contribution decay is now represented in the calculation of Arc Flash incident energy.

Enhanced Arc Flash Evaluation

Here are a few of the many Arc Flash Evaluation enhancements in PTW 6.0:

- Ability to represent generator and synchronous motor decay and accumulated incident energy by using the initial fault contribution for the specified duration in cycles. The reduced fault contribution (entered as a percentage of the Rated Current) is used for the remaining time.

- The Line Side results are now displayed after the Bus results to easily identify the worse case scenario.

- Option for the Line Side and Load Side Arc Flash study to include both line and load side contribution to represent a protective device that fails to open; or to include the line side contribution only when a protective device is being racked-out.

- Recloser is included in the Arc Flash Evaluation. The Response Curve must be identified in the library first. The trip time from the first Response Curve in the TCC will be used in the Arc Flash Evaluation.

- Global Link/Unlink for all or selected Arc Flash functions. This includes bus/branch Bolted Fault Current, TCC Trip Time, Ground, Gap, Equip Type and Working Distance. Global changes of the above values are available.

- Custom Label button in the Arc Flash main screen displays custom label templates and makes label design a great experience. What you see is what you get! PTW prints directly to Thermal Printers with no additional cost for printer software!

- Keyword Table in Custom Labels. User can now replace Keywords with different phrases in English or with other languages.

- Added user-defined background and foreground color, Warning Label text, Head & Eye Protection, Hand & Arm Protection, Foot Protection and five additional user-defined PPE Protection for each category in the PPE Table.

- Updated the Arc Flash Crystal reports to report all study options and project titles.

- New Custom Label Styles for special thermal printers and new Label Styles for weather proof labels that can be printed from regular laser color printers.

Your SKM Support Staff
SKM experienced tremendous success and growth in 2005. With the need to meet client satisfaction and demand, most departments experienced an increase in employee size to account for the added responsibilities. In particular, SKM has more technical support staff than ever to assist you! 

We have more study modules than ever! Take a look at our latest offerings; you may find just the tool you need:

DAPPER -- Integrated set of modules for Three-Phase Power System Design and Analysis including rigorous load flow and voltage drop calculations, impact motor starting, traditional fault analysis, demand and design load analysis, feeder, raceway and transformer sizing, and panel, MCC, and switchboard schedule specification.

CAPTOR -- Produces time versus current coordination drawings with one-line diagrams and setting reports. It lets you coordinate protective devices with interactive on-screen graphics, and provides a comprehensive library.

Arc Flash -- Calculates the incident energy and arc flash boundary for each location in a power system following the NFPA 70E and IEEE 1584 standards. Clothing requirements are specified from a user-defined clothing library.

A_FAULT -- Provides fault calculations in full compliance with the ANSI C37 standards.

IEC_FAULT -- Calculates short-circuit currents using the equivalent voltage source as required by the IEC 60909 standard.

IEC_61363 -- Calculates the current that flows in an electrical power system under abnormal conditions. Represents conditions that may affect typical marine or offshore installations more significantly than land-based systems, including more emphasis on generator and motor decay.

Equipment Evaluation -- Compares protective device ratings with short-circuit calculations.

TMS -- State-of-the-art time simulation program to analyze all aspects of motor starting problems accurately.

HI_WAVE -- Simulates resonance and harmonic distortion in industrial, commercial, and utility power systems.

PTW - I*SIM -- Designed to simulate system response during and after transient disturbances such as faults, load changes, switching, motor starting, loss of utility, loss of generation, loss of excitation, and blocked governor events.

DC System Analysis -- Battery Sizing, DC Load Flow, DC Short Circuit (ANSI), and DC Short Circuit (IEC).

GroundMat -- Substation ground grid design and analysis. It is designed to help optimize grid design or reinforce existing grids of any shape. It uses a general-purpose finite element algorithm for potential analysis and graphical facilities to validate ground system efficiency.

CABLE 3-D -- Quickly solves complex three-dimensional cable pulling tension and sidewall pressure calculations, allowing you to make rapid and accurate design decisions.

PTW-LT - A light version of Power*Tools designed for smaller applications.
