Caterpillar releases SpecSizer 2.7 genset sizing and specifying tool

October 22, 2011 | By Anthony Capkun

October 21, 2011 – Caterpillar Inc. unveiled the latest version of SpecSizer, a software tool that helps engineers select a generator set for electric power projects. Available for PC users, SpecSizer v 2.7.0 features a 20-Step Wizard that automatically calculates the least number of steps for building a load scenario. The wizard collects loads, evaluates voltage dip and load demands, then organizes the loads into steps to help users select a genset with an optimal rating and footprint that minimizes costs. Along with voltage dip and skVA, the tool now provides an additional method for sizing based on customer-specific frequency dips. SpecSizer has been updated with technical specs on several new Cat power systems introduced this year, including gensets, automatic transfer switches (ATS), switchgear and uninterruptible power systems (UPS).
