Abstract: Stimulating power line carrier injection with reactive oscillation comprises exciting a tank circuit to oscillate at the carrier frequency by sinking pulses of current between one node of a capacitor in the tank circuit and the other node of the capacitor. A power transformer is connected to a distribution system to inject power line carrier onto the power line. An excitation circuit sinks short pulses of current between one node of a capacitor and the other node of the capacitor that is connected in a tank circuit arrangement with an inductor and the secondary winding of the power transformer. The tank circuit oscillates at the frequency of the excitation pulses if the resonant frequency of the tank circuit is close to the frequency of excitation. The oscillating current is coupled onto the power line system through the power transformer. The phase of the power line carrier signal is shifted by shifting the phase of the excitation pulses.

Abstract: A voltage indicating device comprises a test port disposed in a casing that allows the test port to operate during extreme conditions, such as corrosive or explosive environments. The indicating device is coupled to a housing enclosing an electrical apparatus and is connected to a power source of the electrical apparatus. The test port is accessible outside the housing and allows a user to determine voltage or current presence prior to opening the housing, thus preventing electrocution.

Abstract: A fuse test and ground device includes an insulated housing with a bore that extends from the front of the housing towards the rear of the housing. An electrical contact is disposed partially within the bore. A current interrupter, such as a fuse, is electrically connected between the contact and a testing ground lead. An eye, having it's surface insulated by the housing, can be attached to the housing and provide a connection point for manipulation of the device. A grounding bore extends from a second aperture into the housing and provides an electrical connection to the contact. A grounding plug can be connected to ground on one end and inserted into the grounding bore to create a permanent ground for the device. An annunciator is connected to the current interrupter such that the annunciator provides an indication when a current flows through the current interrupter.

Abstract: A transformer switch, such as a dual voltage switch or a tap changer. The switch includes a cover, a housing, and a rotor sandwiched between the cover and the housing. The cover and housing are molded from a non-conductive plastic. An interior space of the cover includes at least one pocket within which stationary contacts are disposed. Each stationary contact is electrically coupled to one or more windings of a transformer. The rotor extends within a channel of the housing, from a top of the transformer switch to an interior surface of the cover. The interior surface includes a protrusion about which the rotor and at least one movable contact coupled thereto can rotate. The movable contact is configured to be selectively electrically coupled to at least one of the stationary contacts. For example, different stationary contact-movable contact pairs can correspond to different voltages of the transformer.
