A system includes an electrical apparatus configured to monitor or control one or more aspects of an electrical power distribution network; and a control system including more than one electronic processor, where the electronic processors are configured to cause the control system to interact with the electrical apparatus, an interaction between the control system and the electrical apparatus including one or more of the control system providing information to the electrical apparatus and the control system receiving information from the electrical apparatus, and if some of the electronic processors are unable to cause the control system to interact with the electrical apparatus, at least one of the other electronic processors is able to cause the control system to interact with the apparatus.

Control system for an electrical apparatus

A system for an electrical power distribution network includes an electrical apparatus configured to monitor or control one or more aspects of the electrical power distribution network, the electrical apparatus including a contact switch configured to open and close. The system also includes an input apparatus. The input apparatus includes an impedance module; and an input interface electrically connected to the impedance module and to the contact switch of the electrical apparatus. The input interface is configured to have one of a plurality of input impedances, the plurality of input impedances include at least a first input impedance and a second input impedance that is lower than the first input impedance, and the input interface has the second input impedance when the contact switch of the electrical apparatus is open. The input apparatus may include a plurality of leakage current detection modules.

Input impedance management and leakage current detection

A single common load is provided for both space heating of the interior of an enclosure and for testing of a back-up battery therewith. The common load is coupled to either the battery for momentary load testing thereof, or to a power supply when heat is to be generated by the load for space heating of an interior of an enclosure. Providing only a single load for both space heating and battery testing results in reduced component costs, space savings and simplification of connections and wiring harnesses required. Power resistors, active components such as transistors or MOSFETs, and/or resistive heat tracing may be used as the common load, and deposed within the interior of the enclosure.

Battery test and condensation prevention method, system and apparatus

A multi-phase control system having multi-phase operation with single phase control includes a main control module, a lineman module, and an add-on lineman module. The main control module and the lineman module control, automatically or manually, the first phase and first phase tap changer of a multi-phase system. The add-on lineman module and the main control module control, automatically or manually, additional phases of the multi-phase system. In certain example embodiments, the multi-phase control system detects when a line voltage of an additional phase is de-energized and allows the tap changer of the additional phase to be powered by a line voltage of the first phase. In certain example embodiments, the tap changer of a de-energized phase is powered by an external power supply.

Multi-phase operation with single phase control

Aspects of manual multi-phase voltage control are described. In one embodiment, a voltage regulator controller includes switches for coupling power from an energized phase to a de-energized phase. For example, the voltage regulator controller may include a first power switch electrically coupled to drive circuitry of a first voltage regulator, a first phase output voltage of a multi-phase power delivery system, and a second phase output voltage of the multi-phase power delivery system. In certain aspects, the first power switch selectively toggles an electrical coupling between the drive circuitry of the first voltage regulator and one of the first phase output voltage and the second phase output voltage. Powering a voltage regulator of a de-energized phase with power from an energized phase may peg the operation of the voltage regulator, as necessary, to maintain the balance of the power distribution system, for example.

Manual multi-phase voltage control

A universal-voltage discrete input circuit uses a high voltage depletion-mode field effect transistor in combination with a low-voltage, adjustable precision shunt regulator and an isolation circuit for interfacing a low voltage digital logic circuit to a switched external voltage ranging from about 7 volts to about 1000 volts AC or +/&#x2212; DC, at a low fixed current. In addition to the wide input voltage range accepted at a uniform low current value, very high voltage isolation is provided between the external voltage and the low voltage digital logic circuit, and elimination of ground loops and common mode noise.
