Basic Electrical Power Fundamentals

Figure 1 1 shows the basic building blocks of an electric power system.

Basic electrical power fundamentals.

Understanding basic electrical theory. But what is electricity really. Then we will step through each of these topics in detail. Ac current is produced by all electric utilities.

2 fundamentals of electricity we will start with an overview to introduce you to the main points about these devices and the parts that make them. Basic electrical power fundamentals load reference kilowatts kilovolt amps power factor pf motors kw kva use nec 430 148 kw kva 6 95 and 430 150 to find current for given hp indancescant lighting use actual wattage kw kva 1 0 fluorescent lighting use 50va per 4 foot kw kva 95. It s also important to know who is responsible for what portion of your electrical service. Namely electric charge electric current and electric circuit.

No single discovery has affected our lives our culture and our survival more than electricity. Alternating current ac and direct current dc. The purpose of this info tec is to help you understand the fundamentals of electrical systems. Many problems encountered in service work are electrical problems or related to electrical problems.

Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. The system starts with generation by which electrical energy is produced in the power plant and then transformed in the power station to high voltage electrical energy that is more suitable for efficient long distance transporta tion. Let s start with three very basic concepts of electricity. There are two types of electrical current in common use today.

Electric charge refers to a fundamental property of matter that even physicists don t totally understand. Section title page number introduction to electricity 3 characteristics 3 current 4 voltage 5 resistance 6 review 1 9 ohm s law 10. In this four module program on electrical fundamentals we introduce for study the general physics or basic natural laws that govern the use of electricity.
