Method for recording measurement of e.g. voltage per phase of electrical circuit with load current greater than sixteen amperes in data center, involves providing remote access to data by wide area network

摘要

The method involves detecting electrical voltage levels and electrical current values of an electric circuit and converting the voltage levels and the current values into respective signals. A phase shift and an effect factor are determined from the voltage levels and the current values. Measured or determined data is accessed by a HTTP server and transferred from the server on a local area network (LAN) and a gateway. Remote access to the data is provided by a wide area network (WAN), which works in correspondence with a transmission control protocol (TCP)/Internet protocol (IP). An independent claim is also included for a device for recording electrical performance data with load current greater than 16 amperes.
