A pole top extension is designed to extend the height of the pole, generally through the use of a crossarm or additional attachment. This attachment elevates a span or piece of equipment above the existing height of the pole. Since this is a fairly common practice, a user can model a pole top extension in ..
An essential aspect of performing pole loading in O-Calc Pro is ensuring that the finished product is correct – this process is often referred to as QA/QC, or Quality Assurance and Quality Control. The aim of this article is to address common items that should be checked when performing QA/QC Assessments. While this is not ..
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 ..
