A capacitive load bank or capacitor bank is similar to an inductive load bank in rating and purpose, except leading power factor loads are created, so reactive power is supplied from these loads to the system instead of vice versa. Hence for a mostly inductive load this can bring the power factor closer to unity improving the quality of supply.

Battery energy storage systems are generally designed to be able to output at their full rated power for several hours. Battery storage can be used for short-term peak power [2] and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages. They are often installed at, or close to ...

A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
In the United States, the perfect tender rule refers to the legal right for a buyer of goods to insist upon "perfect tender" by the seller. [1] The rule appears in the Uniform Commercial Code (UCC) § 2-601. [2] The UCC was designed "to simplify, clarify, modernize, and make uniform the law of commercial transactions." [3]
