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 completed design includes circuit diagram and site layout drawings or sketches, a complete bill of materials BOMestimated work requirements, and construction time. For planning and estimating purposes, a team can Chapter 4 contains information on the f modes of power generation.

When installed in parallel with commercial power, prime power can be used for either load sharing or standby. Prime power personnel can make connections to existing distribution networks. When installing secondary distribution, the prime power team’s responsibilities end at the service fk. Engineer prime power units support sustainment engineering efforts by providing reliable power generation and power-related technical expertise.

Prime power operations are conducted by engineer prime power units.

Each prime power team is equipped with four kW generators, giving the team a 3-MW peak power-production capability. 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.

Prime power may be supplemented with portable commercial generation equipment when it is available. All distribution systems are designed and constructed with approved material and methods and include appropriate devices.

The manpower requirements for construction, maintenance, and repair of nonstandard distribution networks depend on a wide diversity mf variables. Appendix A contains a discussion of power-generation concepts. The use of prime power usually requires the construction of nonstandard distribution networks to take power to the users who need it.

Make 20 connections per day to service equipment, load centers, and the secondary side of pad-mounted distribution transformers. These power systems may be encountered in factories or other production plants where large quantities of power are required to operate heavy machinery.

Make 4 connections per day to the primary side of pole-mounted transformers. Maintain 25 kilometers km of overhead cm ground-laid primary distribution line. From the military perspective, electrical power encompasses the entire spectrum of power generation, distribution, and transmission systems that support military operations. In addition to developing specifications for contracts, prime power personnel also help perform the technical evaluation of the bids that are received.

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.

The prime power team is responsible for making the connections to the service equipment. Construct or repair 1, meters of ground-laid primary distribution line per day. Maintain 25 km of overhead or ground-laid secondary distribution line.

Workload estimates for these tasks, which are provided below, are for planning and estimating purposes only and are highly dependent on controlling variables. Once installed and operational, these generators should be turned over to the supported unit to operate and 5422, thus freeing the prime power team for additional missions. Army Regulation AR precludes the purchase of nonmilitary-standard generators without the express approval of the program manager-mobile electric power PM-MEP.


In all cases, the prime power team should work with indigenous power-plant operators or contracted technicians who are familiar with the power plant. Service equipment, which is installed by interior electricians, is the main distribution panel or switched fuse box inside the structure. Commercial power plants and their associated transmission and distribution networks are fixed nonstandard systems.

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 fn a commercial power source to provide power to a user.

They also require the use of transformers, distribution equipment, and switchgear for operation. Design calculations include voltage drops as a result of line loss and grounding requirements. Chapter 4 provides detailed information on prime power missions and capabilities.
