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

An electrical apparatus of an electrical power distribution network may be controlled by accessing, at a control system, one or more operating parameters, the operating parameters being associated with the operation and control of the electrical apparatus; adjusting one or more of the accessed operating parameters, the adjustment being based on data associated with the electrical apparatus; and generating a control signal for the electrical apparatus based on at least one adjusted parameter, the control signal being sufficient to control the electrical apparatus in accordance with the adjusted operating parameter, where controlling the electrical apparatus includes causing contacts of the electrical apparatus to disconnect from each other to prevent electrical current from flowing through the electrical apparatus and causing the contacts of the electrical apparatus to connect to each other to allow current to flow through the electrical apparatus.

Controlling an electrical apparatus

An electrical device, such as a battery charger, a method for operating an electrical device, a method for charging a battery, and a software program for operating the electrical device and/or the battery charger. In some aspects, the battery charger is capable of charging different types of batteries and capable of operating on alternate sources of AC power or alternate sources of DC power. Also, the battery charging circuit will not operate if one of the power source, the battery, the power switch means and the control means (including the microcontroller) malfunctions. In addition, in the battery charging circuit, the battery under charge enables the operation of the battery charging circuit.

A sound dampened solenoid utilizes pneumatic dampening to quiet the sound during the plunger's movement. An O-ring is mounted around the outer diameter of the pole piece thus sealing the pole piece to the solenoid tube. A seal is placed in the pole piece opening where the plunger push rod passes through. A pair of low friction wear bands are wrapped around the plunger. Small gaps are formed where the ends of each wear band meet. A second O-ring is located under one of the wear bands to form a seal between the plunger and the tube. In a pull solenoid, when the solenoid is energized the plunger begins to accelerate toward the pole piece causing the volume of air within the tube between the plunger assembly and pole piece to shrink. The only path for air trapped within to escape is through the gaps in the wear bands. Air is forced through the gaps at a slower rate than the rate of volume change. Air pressure within the volume rises slowing the plunger acceleration and quieting its operation. A method for sound dampening solenoids is also disclosed.
