Relay Symbol Electrical Drawing
In electrical engineering a switch is an electrical component that can break an electrical circuit interrupting the current or diverting it from one conductor to another.
Relay symbol electrical drawing. Resistor capacitor inductor relay switch wire ground diode led transistor power supply antenna. Equipment these can vary dependent upon drawing package used. Symbols electrical symbols electronic symbols.
Reading and understanding electrical drawings. Typical electrical drawing symbols and conventions. Location symbols for general installations machine general symbol function etc load general symbol details motor starter general symbol indicates type etc.
A power circuit consists of the main power device a motor a generator or other power devices along with heavy power conductors contactors. Electrical drawings can represent anything from a single line power distribution to a power or control circuit and are prepared using various symbols for electrical devices and their interconnections with lines representing conductors or wires used for interconnections. 8 control power disconnecting device is a disconnecting device.
Most of the time a small voltage or current is used to switch other voltages or higher currents that may be electromechanical or fully electronic type. Electrical schematics are commonly classified into power circuit and control circuit.
