ISO 14617 Graphical symbols for diagrams is a library of graphical symbols for diagrams used in technical applications. [1] ISO 14617 consists of the following parts: Part 1: General information and indexes; Part 2: Symbols having general application; Part 3: Connections and related devices; Part 4: Actuators and related devices
ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)
Ayrton shunt switching principle. The Ayrton shunt or universal shunt is a high-resistance shunt used in galvanometers to increase their range [1] without changing the damping. [2] The circuit is named after its inventor William E. Ayrton. [3] Multirange ammeters that use this technique are more accurate than those using a make-before-break ...

In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant.
Dynamic voltage restoration (DVR) is a method of overcoming voltage sags and swells that occur in electrical power distribution. [1] [2] [3] These are a problem because spikes consume power and sags reduce efficiency of some devices.
Generator separately excited by battery Self exciting generators Series on left, shunt on right. A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited).
It differs from the ISO control pattern only in that SAE controls exchange the hands that control the boom and the stick. This control pattern is standardized in J1814 [ dubious – discuss ] . In the SAE control pattern, the left hand joystick controls Swing (left & right) and the Main Boom (up &down) , and the right hand joystick controls the ...
