Chapter 1. OVERVIEW. ELECTRICAL POWER. Electrical power is an essential element of military operations. Without it, many crucial systems cease to operate. Field Manual (FM) supports engineer, Army, and joint missions throughout full spectrum operations. This FM provides a doctrinal basis for planning. FM The training and experience of prime power NCOs give them an in- depth working knowledge of electrical and electromechanical systems. Each 52E .

The load survey is a vital preliminary step in providing prime power support. In some cases, nonstandard generators may already be installed as backup. Administrative, health service support HSSand logistical support operations would be seriously jeopardized without it.

FM – Engineer Prime Power Operations –

These power systems may be encountered in factories or other production plants where large quantities of power are required to operate heavy machinery. During operations short of war, the primary objective of prime power operations is to provide prime power generation and power-related technical support to forward presence operations, contingency response, and disaster relief.

The prime power team performs analyses of gm distribution networks to determine their capacity and characteristics. Enter Your Email Address. Make 4 connections per day to the primary side of pole-mounted transformers. The design includes 5-422 of conductors, breakers, switches, transformers, load centers, and other devices. NTG power plants comprise the Army’s family of portable generators larger than kW.

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

Prime power personnel can help develop specifications for electrical performance contracts and purchase contracts for electrical material. Chapter 4 provides 5-422 information on prime power missions and capabilities.

The prime power team conducts a load survey to determine the amount of power a supported unit needs and what the distribution requirements are. Prime power may be employed as a stand-alone power source.

Table shows the various possible configurations and the manpower requirements for fmm operation. The team can configure its generators into one large power plant or two smaller plants. 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 5-4422 in support of military operations.


Supported units may use contracting channels to rent or lease these generators. Because the prime power teams have working knowledge of multiple power systems, they are able to repair, maintain, and operate industrial power systems and their associated controls. This mission statement encompasses military operations across the entire continuum of military operations to include disaster relief, humanitarian assistance, and other operations short of war.

Sign In Sign Out. The prime power team is responsible for making the connections to the service equipment.

This is useful in determining how much power is available on a system 5-242 whether the system is expandable or not. Nonstandard generators are nonmilitary, commercial-type generators. In this role, he acts as an electrical -5422 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.

The team 5-242 also repair and maintain airfield lighting and other specialized illumination systems. Maintain 25 kilometers km of overhead or ground-laid primary distribution line. Prime power personnel can make connections to existing distribution networks. The result of this growing dependence on electricity is a continual increase in the quantity and quality of power required to support operations.

For more complex projects, a critical path method CPM diagram is also produced. The prime power team does conduct a safety inspection of the interior branch circuits and connections before energizing the service equipment. These power systems are part of the infrastructure, as are other utility systems. Responsibility for providing, operating, and 5-42 the generators lies with the user. Performance contracts are needed when a power project exceeds the construction capabilities of the prime power unit or when contracted services are preferred over troop labor.

In all cases, the prime power team should work with indigenous power-plant operators or contracted technicians who ffm familiar with the power plant. Construct or repair 1, meters of ground-laid primary distribution line per day. Prime power units have a limited capability to operate, maintain, and perform damage assessment of some fixed commercial power plants, especially diesel-engine- and gas-turbine-driven plants.


Construction and maintenance of extensive overhead distribution systems should be accomplished through use of contracts. This includes making in-line cable splices but does not include making connections to distribution transformers.

During war, the primary objective of prime power operations is to support force sustainment in the communications zone COMMZproviding power generation and 5-422 technical support to rear-area units, facilities, and activities. Once installed and operational, these generators should be turned over to the supported unit to operate and maintain, thus freeing the prime power rm for additional missions.

Prime power teams are not normally used to perform interior electrical work such as interior wiring. It is also useful in identifying potential electrical hazards that could result in damage to 55-422 equipment, electrocution, or electrical fire. An important consideration when using nonstandard equipment is the availability of service and repair parts. Commercial power plants and their associated transmission and distribution networks are fixed nonstandard systems. The prime power unit also designs temporary, ground-laid distribution systems.

This function is performed by the vertical construction platoon of the combat-heavy, engineer-battalion line companies and by engineer utilities detachments. AFCS is discussed in Chapter 4. Chapter 4 contains information on the three modes of power generation. Make 6 connections per day to the secondary 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.
