FM 5-422 PDF

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 .

NTGs require site preparation for installation. The mission of engineer prime power 5–422 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. The prime power team performs analyses of existing distribution networks to determine their capacity and characteristics.

Construction and maintenance of extensive overhead distribution systems should be accomplished through use of contracts. For planning and estimating 5-42, a team can The indispensable nature of electrical power compels commanders and planners to recognize their electrical power needs and to ensure that those needs are met. AFCS is discussed in Chapter 4.

FM – Engineer Prime Power Operations –

This includes making in-line cable splices but does not include making connections to distribution transformers. From the military perspective, electrical power encompasses the entire spectrum of power generation, distribution, and transmission systems that support military operations. Each prime power team is equipped with four kW generators, giving the team a 3-MW peak power-production capability. These power systems are part of the infrastructure, as are other utility systems. Prime power operations are conducted by engineer prime power units.


This is roughly equivalent to the distribution system of a small rural town.

The prime power team can install, operate, repair, and maintain nonstandard portable generators when they are available. This is useful gm determining how much power is available on a system and whether the system is expandable or not. Some weapons systems are dependent on electrical power for operation.

Prime power teams can construct and maintain temporary, ground-laid or buried primary and secondary distribution systems. When installed in parallel with commercial power, prime power can be used for either load sharing or standby. 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.

Chapter 4 provides detailed information on prime power missions and capabilities. In addition to producing power, the prime power unit performs many other technical power-related tasks.

The completed design includes circuit diagram and site layout drawings or sketches, a complete bill of materials BOMestimated work requirements, and construction time. An important consideration when using nonstandard equipment is the availability of service and repair parts. This mission statement encompasses military operations across the entire continuum of military operations to include 5-42 relief, humanitarian assistance, and other operations short of war.


Maintain 10 km of buried primary distribution line.

FM Table of Contents

The recommended power source is determined based on the load survey. Maintain 10 km of buried secondary distribution line. Engineer prime -5422 units can produce large quantities of reliable power with their organic kW generators. It is also useful in identifying potential electrical hazards that could result in damage to connected equipment, electrocution, or electrical fire.

Maintain 25 km of overhead or ground-laid secondary distribution line. Design calculations include voltage drops as a result of line loss and grounding requirements. The load survey is a vital preliminary step vm providing prime power support. Make 4 mf per day to the primary side of pole-mounted transformers. When installing secondary distribution, the prime power team’s responsibilities end at the service entrance.

Prime power unit personnel cannot operate nuclear and fossil-fuel steam-powered plants or hydroelectric plants. Table shows the various possible configurations and the manpower requirements for continuous operation. Nonstandard generators are nonmilitary, commercial-type generators.

A load survey is an analysis of power requirements.

Make 6 connections per day to the secondary side of pole-mounted transformers. In addition to developing specifications for contracts, prime power personnel also help perform the technical evaluation dm the bids that are received.
