A fault type determination method and device of a terminal unit for automation used in a power distribution network are disclosed. The method includes: for each line of incoming lines and outgoing lines of a distribution device, recording the number of faults occurring on the line; after a fault occurs, determining, according to the current and/or voltage on each line, whether automated reclosing is executed, and recording the number of executed automated reclosings; in a fault type determination period, for each line, if the number of faults occurring on the line is greater than the maximum number of automated reclosings allowed by the transformer substation side, or the fault is a repeat fault, then identifying the fault on the line as a permanent fault.

The present invention relates to a power transducer system configured to operate at a high level of efficiency. Such a power transducer system may comprise various components, all of which may be scalable dependent upon the needs of electrical power to be supplied to a downstream load. In at least one embodiment, such a power transducer system may comprise at least one power cell interconnected with an inverter component. Such an inverter component May be electrically connected with a motor component through a switch component, wherein such motor component may be configured to generate mechanical energy. Such mechanical energy May be subsequently imparted onto a generator component for the generation of electrical energy, such as through an armature component. Such electrical energy may be provided to downstream loads therefrom, with any residual energy generated being recycled back through the system via the switch component.
