An electric power monitoring and response system using electromagnetic field sensors located remotely beside the phase conductors. The system determines unknown system variables for one or more three-phase power lines based on measured values obtained form the field sensors and, in some cases, known power system values. For a given physical configuration, the field sensors may include a magnetic or electric field sensors, and the known system values as well as the unknown system variables may include phase currents, phase voltages and distances defining the physical configuration of the system. The response equipment may be a display, a circuit interrupting device, a voltage regulator, a voltage sag supporter, a capacitor bank, communication equipment, and reporting system.

Electric power monitoring and response system

An AC drive which can be applied to any power using device and in particular is a medium voltage AC drive. In a preferred embodiment, a multilevel AC drive topology is implemented, with the drive including a plurality of inverters and converter electrically coupled through electrical buses and physically coupled through their respective modular bases, and sharing a common cooling system connected to the respective heat exchangers of each component. The AC drive generally is made up of a plurality of inverter modules, which are connected to a converter module, and with each of the above components packaged in a relatively small unit having a cooling apparatus.
