Software tools

Software tools are applications that can help you collect, process, visualize, and interpret the power quality data from different sources. They can also help you generate reports, graphs, charts, and tables that can help you identify and solve power quality problems. They are convenient, versatile, and customizable. You can use them to compare different scenarios, simulate different solutions, and optimize your power quality management. However, software tools also have some disadvantages. They may not be compatible with all devices and formats, they may have bugs or errors, and they may be vulnerable to cyberattacks.
