Key Concepts

Reference Voltage in Calculations

When a permitted percentage voltage drop is specified, it is critical to use the correct reference voltage for accurate computation. In most practical applications, the load voltage is used as the reference because it represents the voltage that the electrical devices receive, ensuring that any voltage drop remains within acceptable operational limits.

Load Voltage

Load voltage is the voltage available at the point where the electrical load is connected, after accounting for losses along the supply path. In voltage drop calculations, the percentage line voltage drop is typically computed based on the load voltage, as it reflects the actual operating voltage of the equipment.

Voltage Drop

Voltage drop refers to the reduction in voltage as electrical current travels through the various components of a circuit, such as conductors and connections. It is an important factor to consider in electrical system design because excessive voltage drop can adversely affect the performance of connected equipment.
