Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.
Lotus 1-2-3 was the leading spreadsheet when DOS was the dominant operating system. [12] Microsoft Excel now has the largest market share on the Windows and Macintosh platforms. [ 13 ] [ 14 ] [ 15 ] A spreadsheet program is a standard feature of an office productivity suite .
Wireless overhead power line sensors hanging from each of the three phases of a 4160 Volt powerline in a residential neighborhood, in Palo Alto, California. A Wireless powerline sensor hangs from an overhead power line and sends measurements to a data collection system.
A distribution management system (DMS) is a collection of applications designed to monitor and control the electric power distribution networks efficiently and reliably. It acts as a decision support system to assist the control room and field operating personnel with the monitoring and control of the electric distribution system.
The term “power system” describes the collection of devices that make up the physical systems that generate, transmit, and distribute power. The term “instrumentation and control (I&C) system” refers to the collection of devices that monitor, control, and protect the power system. Many power-system automation are monitored by SCADA.
Excel has many built in functions that can help break down data and also separate data by scenarios. The user can easily download and add files to their Excel sheets to use for their data. Other tools Excel offers is the use of conditional formatting and basic pivot tables and charts. Excel allows the user to reference other cells which ...
One of the first consequences of implementing the industrial internet of things (by equipping objects with minuscule identifying devices or machine-readable identifiers) would be to create instant and ceaseless inventory control. [30] [31] Another benefit of implementing an IIoT system is the ability to create a digital twin of the system ...
Figure 8 from US patent 4858141 showing how differences in reactive power can help distinguish one appliance from another. The system can measure both reactive power and real power. Hence two appliances with the same total power draw can be distinguished by differences in their complex impedance. As shown in figure 8 from the patent, for ...
