Looking Good Reading Electrical Diagrams
For electrical schematics that detail individual relays and contacts the components are always shown in the de energized condition also called the shelfstate.
Reading electrical diagrams. In order to learn how to read a circuit diagram it is necessary to learn what the schematic symbol of a component looks like. A lamp is usually represented as a circle with a cross inside it. Reading electrical schematics to read electrical system diagrams and schematics properly the condition or state of each component must first be understood.
An electrical schematic is a logical representation of the physical connections and layout of an electric circuit. Nets are lines that will show how components are connected. A well documented schematic outlines the functionality of an electric circuit and provides the basis for assembly and troubleshooting of a system.
A schematic can contain few or many symbols and connections and is normally read from left to right top to bottom. A drawing of an electrical or electronic circuit is known as a circuit diagram but can also be called a schematic diagram or just schematic. Familiarize with standardized electrical symbols knowing the meanings of basic electrical symbols in your electrical drawing will help you quickly understand and troubleshooting the circuit.
It is also necessary to understand how the components are connected together in the circuit. When the current passes through the lamp it will produce light. Recognizing connection and lines in electrical schematics understanding the representation of symbols and components is just the primary stage in reading electrical schematics.
