Disconnect circuit interrupter circuit breakers w thermal ol circuit breakers w magnetic ol limit switches foot switches pressure vacuum switches liquid level switches temperature actuated. Here is an easy to use circuit diagram software coming with ready made circuit diagram symbols that makes it easy for. Electrical diagrams are archived in cdd as hpgl plot files.

The one line diagram is similar to a block diagram except that electrical elements such as switches circuit breakers transformers and capacitors are shown by standardized schematic symbols. Figure 2 circuit drawing line diagram. Locus diagram is presentation of impedance l or c or r where the r is on the x axis and the l c are on the y axis and can be used in the presention admittance and using ohms lw we can get the current in a circuit or voltage on that circuit. Using easy software to make pdf circuit diagram create circuit diagram from ready made symbols and export to pdf with 1 click.

Faraday s laws of electromagnetic induction concept of self and mutual inductance. Analogy between electrical and magnetic circuits. As the value x l is increased from zero i l is reduced and finally where x l is α current becomes zero and θ will be lagging behind the voltage by 90 as. Native cad files of st cv diagrams are also stored in cdd.

The purpose is to help electrical engineers gain a detailed understanding of how the circuit works.
