Australian New Zealand electrical symbols for drafting. Sometimes these lines can also indicate in combination with suitable additional symbols a mechanical interlocking between two or more devices such as contactors or circuit breakers. Power transformers circuit breakers isolators instrument transformers CTs VTs etc by their graphic symbols in the connection schemes.

A preview of the DWG file download. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuitIts basic function is to interrupt current flow after a fault is detected. Whether you are a novice or a professional engineer these basic symbols can help create accurate electrical and circuit diagrams in minutes.

You can depict a complex electrical circuit with the standard and simplified electrical symbols. Single busbar system with sectionalisation. Graphic symbols of substation elements.
