    • Techniques for detecting high impedance conditions in an electrical grid are described herein. In one example, impedance is calculated for each of a plurality of locations within the electrical grid, such as at electrical meters. The impedances may be calculated as a change in voltage divided by a change in current, such as between sequential voltage/current measurements. Statistics may be maintained, including the calculated impedances. In three examples, statistics may be used to identify growth in impedance over multiple days, to identify growth in impedance over multiple hours, and to identify a meter for which impedance is higher than impedance for other meters attached to a single transformer. In a further example, instances of impedance over a threshold value may be identified, from among the maintained statistics. The instances of high impedance may be reported for reasons including cost and safety.
    • 本文描述了用于检测电网中的高阻抗条件的技术。 在一个示例中,针对电网内的多个位置中的每一个,例如在电表上计算阻抗。 阻抗可以被计算为电压变化除以电流变化,例如在顺序电压/电流测量之间。 可以保持统计,包括计算的阻抗。 在三个例子中,可以使用统计数据来识别多天内阻抗的增长,以识别多个小时内的阻抗增长,以及识别阻抗高于连接到单个变压器的其他仪表的阻抗的仪表。 在另一示例中,可以从所维护的统计信息中识别超过阈值的阻抗的实例。 由于包括成本和安全性在内的原因,可能会报告高阻抗情况。

    • Techniques for converting communication packets in a network having multiple nodes are described herein. A node may receive communication packets from one or more neighboring nodes. Each communication packet may include control data and payload data. The node may extract the payload data and store the payload data for a time period. The node may determine whether to concatenate the extracted payload data of the communication packets (e.g., based on destinations to where each of the extracted payload data are to be sent, a supported data rate, an application type associated with the extracted payload data, etc.). The node may concatenate the extracted payload data of the communication packets and send the concatenated payload data to another node in a communication packet.
    • 本文描述了用于在具有多个节点的网络中转换通信分组的技术。 节点可以从一个或多个相邻节点接收通信分组。 每个通信分组可以包括控制数据和有效载荷数据。 节点可以提取有效载荷数据并存储有效载荷数据一段时间。 节点可以确定是否连接提取的通信分组的有效载荷数据(例如,基于所提取的有效载荷数据要被发送的目的地,支持的数据速率,与所提取的有效载荷数据相关联的应用类型等等) 。)。 节点可以连接所提取的通信分组的有效载荷数据,并将连接的有效载荷数据发送到通信分组中的另一个节点。

    • Disclosed is a metrology assembly that utilizes a multi-Hall effect device configuration which eliminates the necessity of a magnetic concentrator. In some embodiments, the metrology assembly includes a substrate or support platform configured to support at least two Hall effect devices per phase of an electricity meter. The metrology assembly may further include one or more electrical conductors coupled to the substrate and configured to conduct electric current. The at least two Hall effect devices may be coupled to the substrate at opposing sides of an associated electrical conductor, each Hall effect device being configured to detect a magnetic field created by the electric current of the associated electrical conductor, and to generate an output.

    • The present disclosure relates to methodologies, networks, and nodes for providing secure transaction routing among network components. Network transactions (messages) may be intentionally routed though networks using different paths where the act of following the particular node paths or traversing particular nodes provides a security enhancing feature for the messages. A transaction receiving node will examine the paths taken from a sending node to determine if the paths correspond to predetermined paths to verify the authenticity of the transaction. In some embodiments, predetermined paths may change in a predetermined sequence where the sequence itself becomes a portion of the security feature.
    • 本公开涉及用于在网络组件之间提供安全事务路由的方法学,网络和节点。 可以通过使用不同路径的网络有意地路由网络事务(消息),其中跟随特定节点路径或遍历特定节点的动作为消息提供安全增强功能。 交易接收节点将检查从发送节点取得的路径,以确定路径是否对应于预定路径,以验证交易的真实性。 在一些实施例中,预定路径可以以序列本身变成安全特征的一部分的预定顺序改变。
