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 prime power team conducts a load survey to determine the amount of power a supported unit needs and what the distribution requirements are.

The units’ power-generation capability allows them to During war, the primary objective of prime power operations is to support force sustainment in the communications zone COMMZproviding power generation and power-related technical support to rear-area units, facilities, and activities. The use of prime power usually requires the construction of nonstandard distribution networks to take power to the users who need it.

Engineer prime power units provide nontactical power generation and power-related technical expertise in support of operations across the continuum of military operations. Supported units may use contracting channels to rent or lease these generators. In 5-22 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.

The prime power unit can train the requesting unit personnel to operate and maintain this equipment. A load survey is an analysis of power requirements. Make 6 connections per day to the secondary side of pole-mounted transformers.

Installation, operation, maintenance, and repair of prime power assets are the responsibility of engineer prime power units. 5-4222

For planning and estimating purposes, a team can Workload estimates for these tasks, which are provided below, are for planning and estimating purposes only and are highly dependent on controlling variables.


The prime power unit also designs temporary, ground-laid distribution systems. This includes making in-line cable splices but does not include making connections to distribution transformers.

The team can install and operate these plants in any of three modes. Prime power units have a limited capability to operate, maintain, and perform damage assessment mf some fixed commercial power plants, especially diesel-engine- and gas-turbine-driven plants. They also require the use of transformers, rm equipment, and switchgear for operation. In all cases, the prime power team should work with indigenous power-plant operators or contracted technicians who are familiar with the power plant.

Once installed and operational, these generators should be turned over to the supported unit to operate and maintain, thus freeing the prime power team for additional missions. Appendix A contains a discussion of power-generation concepts. Without it, many crucial systems cease to operate. The design includes sizing of conductors, breakers, switches, transformers, gm centers, and other devices.

When installed in parallel with commercial power, prime power can be used for either load sharing or standby. The portion of the continuum that is exclusively prime power represents power generation and distribution accomplished by prime power units with their organic equipment.

Prime power personnel can make connections to existing distribution networks. The result of this growing dependence f electricity is a continual increase in the quantity and quality of power required to support operations. The prime power unit commander is the theater’s subject-matter expert for electrical power.

The overlap between prime power and commercial power may occur when a prime power unit repairs and maintains part of a distribution network on a commercial grid or when the unit taps into a commercial power source to provide power to a user. This is useful in determining how much power is available on a system and whether the system is expandable or not.

During operations short of war, the primary objective of prime power operations is to provide prime power generation and power-related technical support 5–422 forward presence operations, contingency response, and disaster relief.

Engineer prime power units can produce large quantities of reliable power with their organic kW generators. In addition to 55-422 power, the prime power unit performs many other technical power-related 5422.


Chapter 4 contains information on the three modes of power generation.

They may also be encountered in facilities such as ports, fuel-storage complexes, hospitals, refrigeration warehouses, and rail-switching centers. The manpower requirements for construction, maintenance, and repair of nonstandard distribution networks depend on a wide diversity of variables. This is roughly equivalent to the distribution system of a small rural town. Prime power is reliable, commercial-grade utility power continuously generated by nontactical generators NTGs.

The mission of engineer prime power units is 54-22 generate electrical power and provide advice and technical assistance on all aspects of electrical power and distribution systems in support of military operations.

Commercial power is provided in the theater by the host nation or nations. It may also be installed in parallel with a commercial power source. Prime power teams can construct and maintain temporary, ground-laid or buried primary and secondary distribution systems.

Construction and maintenance of extensive overhead distribution systems should be accomplished through use of contracts. Vm or repair meters of ground-laid secondary distribution line per day. Each prime power team is equipped with four kW generators, giving the team a 3-MW peak power-production capability. Enter Your Email Address. Enter Your Email Address. The recommended power 5422 is determined based on the load survey. NTG power plants comprise the Army’s family of portable generators larger than kW.

Commercial power plants and their associated 5-42 and distribution networks are fixed nonstandard systems. Sign In Sign Out.

Army Regulation AR precludes the purchase of nonmilitary-standard generators without the express approval of the program manager-mobile electric power PM-MEP. All distribution systems are designed and constructed with approved material and methods and include appropriate devices.
