Method, modules and a system formed by connecting the modules for controlling payloads are disclosed. An activation signal is propagated in the system from a module to the modules connected to it. Upon receiving an activation signal, the module (after a pre-set or random delay) activates a payload associated with it, and transmits the activation signal (after another pre-set or random delay) to one or more modules connected to it. The system is initiated by a master module including a user activated switch producing the activation signal. The activation signal can be propagated in the system in one direction from the master to the last module, or carried bi-directionally allowing two way propagation, using a module which revert the direction of the activation signal propagation direction. A module may be individually powered by an internal power source such as a battery, or connected to external power source such as AC power. The system may use remote powering wherein few or all of the modules are powered from the same power source connected to the system in a single point. The power may be carried over dedicated wires or concurrently with the conductors carrying the activation signal. The payload may be a visual or an audible signaling device, and can be integrated within a module or external to it. The payload may be powered by a module or using a dedicated power source, and can involve randomness associated with its activation such as the delay, payload control or payload activation.

A liquid electrode tip has a housing with a top, a bottom and at least one peripheral side wall. The housing has a liquid inlet and a liquid outlet. The liquid outlet is located at the top of the housing. A solution reservoir is positioned within the housing. The solution reservoir has a solution inlet in fluid communication with the liquid inlet and a solution outlet in fluid communication with the liquid outlet. A conductor is positioned within the housing with at least a portion of the conductor being submerged by a liquid in the solution reservoir. A staging area at the top of the housing is provided into which the liquid from the solution reservoir flows from the liquid outlet.

Embodiments of the disclosure relate to a grid control system for at least one electrical grid. The system includes at least one peer-to-peer network having at least one peer-to-peer application. The peer-to-peer application has a detecting means executable by a part of the nodes of the peer-to-peer network and is configured to detect a first peer-to-peer module assigned to a controllable electrical device upon a connection of the controllable electrical device with the electrical grid. The first peer-to-peer module is configured to communicate with the peer-to-peer application, and the peer-to-peer application includes a registering means executable by at least a part of the nodes of the peer-to-peer network and is configured to store at least one identifier assigned to the detected controllable electrical device and at least one switching pattern of the detected controllable electrical device.

Certain aspects and features include a system and method for monitoring the operational status of assets in an electric power distribution system. For example, an asset monitoring system identifies a zone of operation for an asset under evaluation. The asset monitoring application identifies meters connected to transformers in the zone of operation and obtains meter voltages for the meters over multiple intervals. The asset monitoring application determines a primary voltage for at least one transformer based on at least one meter voltage. The asset monitoring application uses the primary voltage in a power flow calculation to estimate an operational setting for the asset. The asset monitoring application compares the voltages from the power flow analysis using the estimated operational setting and the voltages from the meter voltages across multiple time intervals. Based on the comparison, the asset monitoring application determines an operational status of the asset.
