Abstract: A protection system for an electrical apparatus is disclosed. The protection system includes a baffle assembly and a coating for electrical elements exposed to arc gases. The baffle assembly includes a number of generally planar sidewalls, each sidewall including a first edge surface, a second edge surface, and a third edge surface. The sidewalls are disposed in a spaced, generally parallel configuration defining a number of channels. A first end wall is sealingly coupled to each sidewall first edge. A second end wall is sealingly coupled to each sidewall second edge. A third end wall is sealingly coupled to each sidewall third edge. The terminals of an electrical apparatus are disposed in an aligned set with one set of terminals in each channel. The channels are structured to limit the flow of arc gases across adjacent sets of terminals.

Abstract: A power pole inverter is provided. The power pole inverter includes a housing assembly, a capacitor assembly, a number of arm assemblies, a number of heat sinks, and a support assembly. The housing assembly includes a number of sidewalls. The housing assembly sidewalls defining an enclosed space. The capacitor assembly is coupled to the housing assembly. Each arm assembly includes a plurality of electrical components and a number of electrical buses. Each the electrical bus includes a body with terminals, each the terminal structured to be coupled to, and in electrical communication with, the capacitor assembly, each arm assembly including a neutral terminal. Each arm assembly is coupled to, and in electrical communication with, the capacitor assembly. The support assembly includes a non-conductive frame assembly. The support assembly is structured to support each the heat sink in isolation.

Abstract: A system includes a variable frequency drive (VFD) comprising an inverter having an output configured to be coupled to a motor and a switch configured to couple a power source to the motor to bypass the VFD. The system further includes a control circuit configured to synchronize the VFD to the power source, to operate the switch to couple the power source and the VFD in parallel and to subsequently disable the inverter responsive to a current of the inverter. In some embodiments, a PWM frequency of the VFD may be temporarily increased when transferring the motor from the power source to the VFD.
