January 30, 2018 Dear Colleague, Its Launch Day and we are proud to announce the 1st ever *automatic*, *graphic* and *simultaneously* generated 1 Line Diagram. You talked, we listened...and the result is the one and only *real time* 1 Line Diagram on the planet. Our patented technology calculates all the values for the 1 Line Diagram with our 7+ million equations. And now, these electrical engineering values are *also visual*. *PowerCalc* makes electrical engineering design *so easy*! We have a brief introduction for you.  We all know that a picture is worth a thousand words, but up until now, for electrical professionals seeing the 1 Line Diagram has not been possible until the end of the design process and after days, weeks and months spent designing. The 1 Line Diagram has been a one-off, after the fact exercise at the end of the project put together using a separate application.   [![Register For Webinar Now](https://no-cache.hubspot.com/cta/default/1002713/0b3bdaf0-0332-49cc-af77-7c99423a67bd.png)](https://cta-redirect.hubspot.com/cta/redirect/1002713/0b3bdaf0-0332-49cc-af77-7c99423a67bd)     What is the 1 Line Diagram? It is a graphic and simplified notation for representing a 3 phase power system required for permitting in commercial buildings. The values on the  1 Line Diagram evidence that the 3 phases of the electrical design are balanced.   In new construction, the entire power distribution system must be summarized with a 1 Line Diagram. And for renovation*, PowerCalc's* 1 Line Diagram also serves as the starting point to determine the renovation design's impact on the existing power distribution system.   Watch *PowerCalc's* technology in action on a school for the Broward County School System...the largest school system in the country. *See the full length demo.*  [![New Call-to-action](https://no-cache.hubspot.com/cta/default/1002713/10e59aa5-111d-442d-9d7f-50475c950e3f.png)](https://cta-redirect.hubspot.com/cta/redirect/1002713/10e59aa5-111d-442d-9d7f-50475c950e3f)   Our software is a fully integrated design application that *saves* you *time* and *money*.
