toggle menu Unbalance Calculator This application is your tool to estimate the effect of load unbalance in your electrical system and to calculate your need for active load balancing to the reach the desired unbalance level. The application prints the summary of the results on the web page and sends a more specific report to your e-mail. Please refer to Unbalance Calculator User Guide for help with Unbalance Calculator Personal information Please provide your name, company and a valid e-mail address to deliver the report to.
