How do I read electrical diagrams?

Electrical diagrams are schematic drawings used to describe electrical circuits. These drawings are created for any product that uses electricity, from electrical equipment throughout the building. The terms and symbols used are consistent regardless of the application. Electrical diagrams are usually created by electrical engineers for products and architects for buildings.

When reading electrical diagrams, you must remember three things about all electrical circuits. The first item is that all circuits must move electricity from one place to the other. From a practical point of view, each circuit has a clear beginning and purpose.

The second item is the control. There must be a way of controlling the amount of electrical force in the circuit. The third item is that each circuit must begin and end for a voltage source. These sources may not be the same, but there must be a complete loop.

Electrical diagrams use internationally Acccept Standard Symbols to represent different items. Most electricThe drawings include a legend or key, providing an explanation of each symbol. These symbols are consistent worldwide and provide a quick method to identify the way the circuit work and solve problems with potential problems.

For example, a line of a line with a coil around it is a relay or an automatic switch. The legend provides an accurate image with a letter code, such as "C" for the coil. Each picture of the coil will have the same symbol, but will be uniquely numbered in the order. Inside the picture is a circle used to record a letter that corresponds to a set of contacts that are operated by this coil. The amount of electricity in the circuit is written in volts along the circuit line.

If there are any limitations of the perimeter or electrical output voltage, this value is written on the actual item. The switch or control is displayed by interrupting the direct circuit at an angle of 20 degrees. It turned out thatE space indicates a turning point, the line is restarted on the opposite side and continues to the source.

When reading an electrical diagram, start with the main energy source. Follow the perimeter with your finger and find out where it is going and what it is doing. Repeat this process with all circuits. This method takes time, but provides a valuable insight into the circuit operations as connected and the basic product design.
