摘要： A modular water treatment system includes a plurality of water treatment components including selected from a group of a particulate filter component, a taste and odor filter component, a lead and mercury filter component, a water softener component, and a water disinfection component. A plurality of interfaces are provided for coupling to the selected water treatment components. Plumbing lines provide flow communication between the selected water treatment components, and the plumbing lines include a system water inlet and a system water outlet. A controller is configured to control the flow of water through the system, and a sensor is configured to transmit a signal to the controller.

摘要： A method and apparatus are provided for protecting a non-isolated data communications cable against ground skew used with an AC power source. A current summing transformer is coupled to an AC power source. The current summing transformer includes a single transformer core and a plurality of coils. One of the coils is connected in series with each phase, neutral (if present) and ground line in the AC power source. The plurality of coils are substantially identical. Each coil has an identical number of turns and an identical direction of winding on the transformer core. The current summing transformer is only needed in the power path to one of two or more interconnected systems. The current summing transformer introduces a high impedance to surge current in the data cable ground of one or many non-isolated data cables attached to the system and at the same time offers substantially zero impedance to the normal power currents including leakage and fault ground currents.
