The O-Calc Pro Master Catalog features an extensive list of components that can be included in a pole model. Of those components, the loadcase component acts as the driving force behind the calculations that are performed. The ‘Load Cases’ folder contains the safety requirements for the National Electric Safety Code (NESC), General Order 95 (GO95), ..
The DMT Process refers to the use of the Digital Measurement Technology in O-Calc Pro. This technology typically requires a photograph of a pole be taken with a CVT, or Calibrated Visual Target, attached to the pole. This CVT is used in O-Calc to obtain height measurements for various attachments. With the release of O-Calc ..
O-Calc Pro contains many features designed to enhance the accuracy of a pole model. In some cases, accurately modeling all available parameters of a pole can indicate that a pole does not comply with pole loading code requirements so its allowable capacity utilization exceeds 100%. When a pole’s groundline capacity utilization exceeds 100%, the pole ..
The O-Calc Pro Master Catalog contains many items that can be modeled on a utility pole. However, not all items found in the field can be found in the catalog. For this reason, O-Calc Pro has the ability to model items as generic equipment using a blend of shapes with different attributes. One common piece ..
Osmose endeavors to test O-Calc Pro on as many different systems and configurations as possible but occasionally there are installations that do not operate correctly due to unanticipated system setting, other installed security software, or non-standard drivers. When this happens O-Calc Pro provides tools to help diagnose and address these problems. One of the most ..
The default tension type of a span pulled from the Master Catalog is always Static Tension. When a span is added to a model, the Static Tension is calculated using a percentage table that can be set by the user. If then, that span is taken from the pole and placed into the User Catalog, ..
O-Calc Pro is a pole loading software designed to inform the user of pole failure, which is the result of a pole being overloaded. An overloaded pole has a capacity utilization value that exceeds 100%. This means that the load being applied to the pole exceeds the amount that the pole can support. There are ..
The field practice of “topping” a pole can be modeled successfully in O-Calc Pro. When a pole is “topped”, a portion of the top of the pole is cut off. This could be for a number of reasons, like pole tip deterioration, or the desire to use a heftier class pole that isn’t necessarily very ..
The DMT, or Digital Measurement Technology, process in O-Calc Pro allows a user to obtain information from a photo of a pole that was taken with a CVT, or a Calibrated Visual Target. This technology allows a user to obtain attachment heights, span diameters, and other information. However, if a photo is taken without a ..
O-Calc Pro determines the overturn moment of a pole based on the technique detailed in RUS Bulletin 1724E-200. The overturn moment is calculated as follows: P = (S * (D ^ 3.75)) / (L – 2 – 0.662 * D) Where P represents the horizontal force in pounds 2 feet from the top that will ..
