摘要： An intelligent electronic device (IED) integrating a power metering unit (PMU) and a merging unit that combines signals from both analog transformers and digital transformers into a set of merged digital samples. Analog current/voltage signals from analog CTs/PTs are received at the IED's analog inputs and converted to digitized samples. Digital current/voltage samples from digital CTs/PTs are received via point-to-point connections at digital inputs of the IED. A tagging unit applies metadata tags to the digitized and digital samples. The metadata tags include the transformer providing the input signal, sampling rate, primary and/or secondary timestamps, scaling values, calibration values, and/or the location of the IED in the electrical system. The PMU performs metering and/or power quality calculations on the samples, and the calculation results are formatted and transmitted via a master-slave protocol to a requesting master. A grouping unit groups the merged samples into default or custom groupings, which are formatted and transmitted over a network via a publish-subscribe mechanism.

摘要： A high ampacity busbar includes a pair of oppositely facing bowl-shaped conductors, each of whose cross sections resembles half of a hexagon or an open isosceles trapezoid, separated by an air gap in both horizontal and vertical configurations. The air gap increases cooling efficiency by natural convection by exposing more surface area of the conductors directly to the air flow within the electrical distribution equipment cabinet. As a result, the overall temperature of the bus system is reduced. The shaped conductors have smoother transitions presented to the electrical current between the bends of the conductors. These smooth transitions improve current distribution throughout the conductor, reducing skin effects. As a result of improved thermal dissipation and reduced skin effects, the amount of copper needed to maintain the same ampacity is significantly reduced. Magnetic shields can be placed between adjacent busbars, reducing proximity effects.
摘要翻译：高容量母线包括一对相对的碗形导体，每个横截面类似于六边形的一半或开放的等腰梯形，在水平和垂直构造中都被气隙隔开。通过将导体的更多表面直接暴露在配电设备柜内的空气流中，空气间隙通过自然对流来提高冷却效率。结果，总线系统的总体温度降低。成形导体对导体弯曲之间的电流呈现更平滑的转变。这些平滑过渡改善了整个导体的电流分布，减少了皮肤的影响。由于热耗散改善和皮肤效应降低，维持相同载流量所需的铜量显着降低。磁屏蔽可以放在相邻的母线之间，减少邻近效应。

摘要： An automatic method of which days/hours represent good candidates for reducing demand to achieve potential savings and the amount of demand reduction that can be achieved with a tolerable level of disruption to status quo operations. Demand interval data including utility usage rate (UUR) values is received from one or more utility monitoring devices, and are sorted in descending order. A percent difference is calculated for each UUR value relative to the previous one, and a cumulative percent difference accumulates the percent differences from the preceding rows. The average cumulative percent difference is divided by the total number of UUR values in the measured period to produce a ratio. The standard deviation of time is determined, and from those demand data associated with ratios greater than a ratio threshold and standard deviations less than a standard deviation threshold the demand reduction amount and the number of control hours are determined.

摘要： A multi-master serial bus that connects multiple utility monitoring devices with multiple remote electronic display units. The display units include an I 2 C microprocessor with an integrated LCD controller for controlling an LCD display and a set of buttons for changing what is displayed on the LCD display. They also include an I/O to I 2 C driver for sending button key presses to the remote monitoring device, which communicates the requested data to be displayed back to the display unit via the multi-master serial bus. Each remote electronic display unit has a unique address assigned to it, and when a user input is detected on the I 2 C bus by the utility monitoring device, the controller in the utility monitoring device sends monitored data to the detected address for display on the remote electronic display unit.

摘要： A circuit breaker lock-off device is side-mounted to a circuit breaker case in a tenacious engagement. The lock-off device has a generally planar body carrying a lock-off arm pivotable in a plane parallel to the body to place an engagement tab extending therefrom into a position for preventing movement of the breaker handle without being physically attached to the breaker handle. The lock-off arm and the body further have complementary rings for accepting a padlock shackle in the locked off position. The invention allows a rugged lock-off accessory which is field installable and which can accommodate various breaker handle geometries.

摘要： An automated integrated monitoring (IM) algorithm that automatically puts data from a utility monitoring system into context by temporally aligning the data to a common reference point and by identifying the location of each monitoring device in a hierarchy relative to other devices. Frequency variation data is received from all meters. The data is automatically aligned to a common reference point, such as a precise zero crossing, using a cross-correlation algorithm to determine the time delay at which the data is most correlated. Once the data is aligned, power data is received from all meters in a hierarchy, and the monitoring system layout is auto-learned using a correlation algorithm to determine which two meters are most likely correlated with one another based upon their historical power readings. Once the layout is complete, additional decisions regarding hardware and software configuration can automatically be made by the IM algorithm.
