Power, definitions electric generation

The next step of demonstration and pioneer plants from the standpoint of the utility industry is appropriate to provide 50-100,000 barrel quantities of these new fuels to complete the definition by the utility industry to transport, store, handle and utilize in electric generating equipment to generate power. 

When appropriate, the chain is extended further upstream to include production of brine, for example by solution mining. Also, because the chlor-alkali plant is a major user of electric power, it is sometimes convenient to include the power generation plant within the chain. For the purposes of this chapter, however, the definition of the vinyl chain shall be restricted to the five processes listed above (Fig. 21.1). 

VAC-U-MAX Compressed-Air Powered Vacuums, are the first-line offerings for Class II, Division 2 environments due to their bumper-to-bumper grounded and bonded design and their reasonable cost and availability. These vacuums meet the NFPA 77 and 654 requirements for grounding and bonding. These vacuums also meet the definition of an intrinsically-safe system". VAC-U-MAX air-powered vacuums do not use electricity and do not generate any heat from operation. 

A. Definitions. The following definitions from 1926.968 relate to work on or near electric power generation, transmission, and distribution lines and equipment and the electrical hazards they present. 

An electrical element or network is said to be passive if the power delivered to it, defined in accordance with Eq. (2.14), is nonnegative. This definition exploits the requirement that the terminal voltage v(t) and the element current i t) appearing in Eq. (2.14) be in associated reference polarity. In contrast, an element or network to which the delivered power is negative is said to be active that is, an active element or network generates power instead of dissipating it.
