Abstract: Techniques are described for providing an automatic transfer switch (ATS), such as in a data center, to determine whether the power system coupled to a first power input on the ATS is the same power system or a different power system that is coupled to a second power input on the ATS. The ATS determines and compares the electrical characteristics (e.g., voltage, current harmonics, etc.) to determine if there is a difference between the determined characteristics. If the electrical characteristics are substantially similar, then a single power system is coupled to both power inputs on the ATS. But if the electrical characteristics are significantly different (e.g., the difference in the electrical characteristics is above a threshold), the power system coupled to one power input on the ATS is different from the power system coupled to the other power input on the ATS.
