The result of this growing dependence on electricity is a continual increase in the quantity and quality of power required to support operations. Installation, operation, maintenance, and repair of prime power assets are the responsibility of engineer prime power 5-422. These power systems may be encountered in factories or other production plants where large quantities of power are required to operate heavy machinery.

The prime power unit provides power-related technical advice to the appropriate engineer staffs. Make 4 connections per day to the primary side of pole-mounted transformers.

Army Regulation AR precludes the purchase of nonmilitary-standard generators without the express approval of the program manager-mobile electric power PM-MEP. Prime power teams can construct and maintain temporary, ground-laid or buried primary and secondary distribution systems.

The load survey is a vital preliminary step in providing prime power support. For planning and estimating purposes, a team can 5-4422 power unit personnel cannot operate nuclear and fossil-fuel steam-powered plants or hydroelectric plants. Maintain 25 kilometers km of overhead or ground-laid primary distribution line.

Continuous operation of large fixed plants exceeds the manpower capabilities of the team. These power systems are part of the infrastructure, as are other utility systems.

Prime power is reliable, commercial-grade utility power continuously generated by nontactical generators NTGs. Nonstandard generators are nonmilitary, commercial-type generators. The recommended power source is determined based on the load survey.

From the military perspective, electrical power encompasses the entire spectrum of power generation, distribution, and transmission systems that support military operations.


Prime power units have a limited capability to maintain overhead distribution systems. In this role, he acts as an electrical engineer staff officer to the theater engineer in a mature theater, or to the supported headquarters when a theater engineer is not available, providing information and recommendations on power-related issues.

It ranges from the power produced by the smallest tactical generators TACGENS through prime power to the power produced and distributed by the largest commercial power plants and their associated transmission and distribution networks.

Command, control, communications, and intelligence C 3 I functions are highly reliant on dependable electrical power. A thorough load survey must be completed before work can begin on the installation of a power plant or the design of a distribution system. Commercial power plants and their associated transmission and distribution networks are fixed nonstandard systems.

Make 12 connections per day to the primary side of pad-mounted distribution transformers.

In addition to developing specifications for contracts, prime power personnel also help perform the technical evaluation of the bids that are received. The prime power team conducts a load survey to determine the amount of mf a supported unit needs and what the distribution requirements are.

Electrical power is an essential element of military operations. This is roughly equivalent to the distribution system of a small rural town. AFCS is discussed in Chapter 4. Output capacity of ffm power plants may vary from a few megawatts MW to several thousand MW. For more complex projects, a critical path method CPM diagram is also produced.

FM Chptr 1 Overview

The prime power team can perform damage assessment of nonstandard power-generation equipment and, fj to availability of repair and service parts, repair the equipment and return it 54-22 operation. The prime power team does conduct a safety inspection of the interior branch circuits and connections before energizing the service equipment.

Make 6 connections per day to the secondary side of pole-mounted transformers. NTGs require site preparation for installation. The mission of engineer prime power units is to generate electrical power and provide advice and technical assistance on all aspects of electrical power and distribution systems in support of military operations.

This includes making in-line splices but does not include making connections to distribution transformers, load centers, or service equipment. Prime power may be employed as a stand-alone power source. Engineer prime power units can produce large quantities of reliable power with their organic kW generators. Engineer prime power units support sustainment engineering efforts by providing reliable power generation and power-related technical expertise.

Make 20 connections per day to service equipment, load centers, and the secondary side of pad-mounted distribution transformers.

Responsibility for providing, operating, and maintaining the generators lies with the user. In some cases, nonstandard generators may already be installed as backup. Each prime power team is equipped with four kW generators, giving the team a 3-MW peak fn capability. The indispensable nature of electrical power compels commanders and planners to recognize their electrical power needs and to ensure that those needs are met.

All distribution systems are designed and constructed with approved material and methods and include appropriate devices. The load survey also determines the level of vm required and identifies any special power requirements or problems. Without it, many crucial systems cease to operate. The prime power unit also designs temporary, ground-laid distribution systems. They provide a mobile source of power to units operating in the field. The team can install and operate these plants in any of three modes.

Prime power units satisfy the critical electrical requirements above the capability of TACGENS and below the availability of commercial power.

Sign In Sign Out. Prime power teams are not normally used ffm perform interior electrical work such as interior wiring. The team can also repair and maintain airfield lighting and other specialized illumination systems. The completed design includes circuit diagram and site layout drawings or sketches, a complete bill of materials BOMestimated work requirements, and construction time.
