It is the most common type of electrical drawings and are mostly used in implementing electrical circuits by technician. Related Post: Types of Fire Alarm Systems and Their Wiring DiagramsĪ power wiring diagram, also known as an electrical power distribution diagram, is a schematic representation of an electrical system that specifically focuses on illustrating the distribution of electrical power within a facility, a complex electrical network or specific electrical circuit.Each block is a complicated circuit that can be explained using other drawings techniques described below. The block diagram provides an idea how the process is done by not delving too deep into the electrical terms but it is not enough to implement a circuit. It is quite a complicated process but this diagram simplifies the process into blocks for better understanding. This block diagram shows a 3 phase AC power supply conversion into a DC which is again converted into a controlled AC supply. Practically, the FM transmitter does not look like this, because the block diagram omits the individual components. Each block process the signal and pass it to the next one. It is pretty simple and easy to understand. This diagram shows the process of converting an audio signal into frequency modulated signal.
#KINDS OF DIAGRAM DRIVER#
The following two examples of block diagram show an FM transmitter and a variable frequency driver VFD. This is why electricians do not rely on block diagram. It only represents the main components of the system and ignores any small components.
It lacks the information about the wiring and placement of individual components. It is the simplest form of electrical drawings as it only highlights the function of each component and provides the flow of process in the system.īlock diagram are easier to design and is the first stage in designing a complex circuit for any project.
