Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

Symbols

Three-phase conductor group

A conductor group represents the documented phase conductors of a circuit shown individually. Drawing the phase conductors individually expands a system that may also appear as one line in an SLD. The individual view makes terminations and phase mapping visible.

Drawing use: SLD / Schematic
Application: Power distribution
Reference family: Manufacturer

A distinction that matters

A three-line group is different from a single-line equivalent representation of the same system.

Symbols

Power converter / inverter

A power converter changes electrical power between the circuit forms specified for its application. In a battery energy storage system, a power conversion system commonly provides the interface between DC storage and an AC system. Direction of power flow and operating capabilities are product-specific.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

Inverter, converter and PCS can denote different equipment boundaries. Define what is included in the represented assembly.
