Course Description

UNDERGROUND LINE DESIGN AND SUBDIVISION LAYOUT: The components of underground distribution systems, along with their application and limitations, will be discussed. The student will learn how to layout subdivisions, specify pad-mounted equipment, and design sectionalizing systems. This course will also cover conduit systems and the correct methods for calculating pulling tensions relative to conduit bends and cable runs.

  1. Underground cable
  2. Components
  3. Pad-mounted switchgear
  4. Over-voltage protection
  5. Cable pulling in conduit systems
  6. Designing underground systems

SIZING TRANSFORMERS AND CONDUCTORS: The seminar will focus on basic electric theory, and the methodology to correctly size transformers and service conductors for standard residential and small commercial loads. The student will learn how to perform basic calculations for current, voltage, power, and voltage drop.

  1. Basic electric theory
  2. Transformers
  3. Transformer sizing
  4. Service voltage drop
  5. Computer programs

BASIC SECTIONALIZING AND LINE EQUIPMENT: The seminar will give the student a basic understanding of fault currents, sectionalizing devices, voltage regulators, and capacitors. The focus of this section will be to teach the staking technician how to apply and locate these devices on the distribution system when the line is being staked.

  1. Principles of over-current protection
  2. Fault current calculations
  3. Over-current protection
  4. Transformer protection
  5. Line coordination
  6. Regulators
  7. Capacitors

CONSTRUCTION CONTRACTS: Accurate accounting of materials and close monitoring of the contractor’s progress are essential to completing a project on time and on budget. The student will learn how the construction contract affects every aspect of the project, how to prepare special conditions and units, and how to administer the contract terms and conditions for a successful outcome.

  1. RUS construction contracts
  2. Plans and Specifications
  3. Staking for a construction contract
  4. Contractor observation
  5. Contract closeout
