Program 7
Software applications in this program may have been updated in the subsequent program. Please check here to see complete list of enhancements:
Project 1 - Distribution Engineering Toolbox
Develop a collection of Windows-based software tools to support routine distribution engineering operations. Included are applications for guy tension calculation, transformer loading analysis, cable pulling tensions, overhead line design (sag, blowout, loading), voltage drop and flicker analysis, and others. Stressed are user convenience and ease of customization to individual utility preferences.

Project 2 - Secondary Electrical Design Software
Develop a graphic-oriented, user-friendly, Windows-based software to support the electrical design of single-phase secondary systems. Program allows user to "draw in" a radial circuit topology with multiple layers of connection nodes, and up to 25 loads. Program assists designer in transformer selection of the appropriate transformer rating. Service voltage regulation, transformer and secondary cable loading, voltage flicker, and service short-circuit currents are easily calculated

Project 3 - Transformer Scrap/Repair Decision Software
Develop a methodology and supporting software to generate decision criteria which can be used by a utility to make a rational, economic-based decision on whether to scrap or repair a transformer which has been removed from service.

Project 4 - Cable Electrical Parameters Software Enhancement
Enhance the capabilities of the Cable Electrical Parameters Software (CEPS), developed previously in Project 6-6, to include secondary cables and paper-insulated, lead-covered primary cables.

Project 5 - Riser Cable Ampacity
There are several aspects of present riser cable rating procedures that lead to questions concerning their accuracy and applicability. First, there are some aspects of the models have not been confirmed with field or laboratory measurements. It is also unknown how well the present rating procedures apply to riser constructions other than cables installed in conduits. This is of importance since many DSTAR members use PVC or painted steel U-guards for riser cable installations. These uncertainties about riser cable rating procedures resulted in a DSTAR field test program for commonly used riser cable constructions. Results of these tests were then used for verification of riser cable rating procedures.

Project 6 - Elbow Flashover Incident Reporting
Develop and deploy a web-based database to gather reports of flashovers of separable connectors (elbows and insulated caps) from the utility industry. Emphasis will be on flashovers occurring during lightly-loaded or unloaded conditions. Data will be gathered describing the equipment, the switching operation, and system characteristics. The gathered data will be periodically analyzed and results presented.

Project 7 - Cable Temperature Effects of Limited-Distance Heat Sources
Perform full-scale field testing to confirm the analytical predictions of cable temperature rise (and resulting need for cable derating) due to heat sources, such as other cables, crossing or in parallel to a cable for a short distance. Included are tests of temperature rise in the short tap sections at padmounted equipment where incoming and outgoing cables may be laid in the same trench for the distance between the equipment and the main cable trench. Previous analytical work shows the need for significant derating in this situation.

Project 8 - DSTAR Seminar
Provide a tutorial seminar reviewing the significant findings of DSTAR research and development. A portion of this seminar will be open to all utilities, and a portion containing the most critical facts will be limited to participants from the funding utilities.
