A protection system described herein includes a first connector, a second connector, and a voltage-limiter device. The first connector is configured to connect to a first load-side terminal of an electric meter, and the second connector is configured to connect to a second load-side terminal of the electric meter. In a circuit between the first connector and the second connector, the voltage-limiter device is configured to clamp a voltage between the first and second load-side terminals at a trigger voltage, to prevent a greater voltage from reaching the electric meter when a service-disconnect switch of the electric meter is open and an external voltage greater than the trigger voltage is applied to a load side of the electric meter. The voltage-limiter device provides a conductive path in parallel with a customer premises associated with the electric meter when the voltage between first and second connectors reaches the trigger voltage.

Embodiments of the disclosure are directed towards electricity fraud detection systems that involve a behavioral detection ecosystem to improve the detection rate of electricity fraud while reducing the rate of false-positives. More specifically, machine learning algorithms are eschewed in favor of two separate models that are applied sequentially. The first model is directed to improving the detection rate of electricity fraud through the use of detectors to identify customers engaging in suspicious behavior based on the demand profiles of those customers. The second model is directed to reducing the rate of false-positives by identifying potential legitimate explanations for any suspicious behavior. Subtracting away the suspicious behavior with legitimate explanations leaves only the identified, unexplained suspicious behavior that is highly likely to be associated with fraudulent activity.

A method for implementing a micro grid within a Smart Distribution Power Grid (SDPG) has steps for connecting a smart meter enabled to sense voltage, to sense current and current direction and to communicate wirelessly to individual ones of consumer sites within an area of the micro grid, determining a set of Smart Distribution Nodes of a number, placement and data packet transfer technology to transfer data from the smart meters to a Micro Grid Controlling Station (MCS), the set determined in a manner to provide cost optimization, where cost is determined form at least original node costs, data packet hops, operating costs and maintenance costs, and implementing the set of SDNs along a power grid topology (PGT) of the micro grid, such that data is transmitted from each smart meter to a proximate SDN and through other SDNs to the MCS.

A power metering apparatus, a power metering server, and a power metering method based on a blockchain are disclosed. Particularly, in order to simultaneously assure integrity and transparency of power metering data based on a blockchain, power metering data generated by measuring an amount of power generated by an energy source and a unique key are stored in a database linked to a power metering server, and a digitally signed hash value of the power metering data is stored in a blockchain node. Accordingly, disclosed are blockchain-based power metering system and method for preventing forgery and tampering of power metering data, solving a problem associated with a blockchain storage capacity that may occur when storing the power metering data, and protecting sensitive information on the power metering data.

The present disclosure provides for enterprise security in intelligent electronic devices such as electric power meters. In accordance with the present disclosure, enterprise security is a security system in which each individual device, instead of configuring and storing security configurations locally, use a security server for security verifications. Such a security server of the present disclosure may be a dedicated computer on a network, that is used to manage the security configuration for all users. This makes it simpler for administrators to configure users and devices, which in turn improves security by encouraging security to be properly configured.

A cover for an electrical rail mount device is provided. Further, an electrical rail mount device for mounting on a rail is provided, comprising at least one input terminal configured to receive an input line, fixing means configured to fix the input line to the input terminal to establish an electrical connection, a lockable cover reversibly movable from an open state into a closed state, whereas the cover is configured to cover the fixing means in the closed state, such that the fixing means can only be accessed by moving the cover from the closed state into the open state, an electrical element arranged in the cover and configured to provide an electrical function to an active electronic element of the electrical rail mount device, wherein an electrical connection is provided between the electrical element and the active electronic element.

Detection and correction of technical and non-technical errors in smart grid power distribution are described. A system, method and non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, causes the one or more processors to perform a method for detecting and correcting technical and non-technical power losses in a smart grid that feature the following functions: remotely characterizing and updating the cables impedances, detecting and classifying the types of losses, estimating the technical and non-technical power losses when a check or smart meter is in error, estimating losses due to tapping a power cable by a registered or an unregistered user, and estimating losses due to a cyber attack. Technical errors corrected are impedance and reactance losses in the power distribution. Non-technical errors identified and corrected are no error, check meter in error, smart meter in error, tapping service cables, or cyber attacks.

Provided is a system, comprising: an electrical power meter comprising: a network interface; electrical power inputs configured to receive electrical power from a power-distribution system of a vehicle facility configured to host a plurality of vehicles; first and second electrically controlled switches coupled to vehicle power connectors; and a client-side processor configured to communicate with a remote server system; and the remote server system, configured to: cause a user-computing device of a user to display a user interface by which power-delivery is configurable; receive a request to deliver electrical power via a vehicle power connector; and in response, transmitting, to the electrical power meter, a command that causes the client-side processor to adjust the electrically controlled switch.

An electric utility metering system for preventing theft of electricity is disclosed. Theft is prevented by making the meter inaccessible to the customer. Generally, theft of electricity is accomplished by a customer electrically bypassing the meter. Theft therefore is prevented where the customer cannot realistically access the meter. Under the present invention, the meter, and the meter socket (if any) are suspended in a service span between the public utility electric service source and the public utility customer unit. In an alternative embodiment, the meters may be encased in a cabinet or simply placed in a housing with the transformer. Where a cabinet is used, the cabinet may be placed underground, or it may be adjacent to the transformer.
