A device, either physical or software-based, designed to compute the power, measured in kilowatts, utilized in a three-phase electrical system. It allows for the determination of electrical consumption based on input parameters such as voltage, current, and power factor. An example involves inputting values of 480 volts, 20 amps, and a power factor of 0.8 to derive the kilowatt value of the circuit.
The calculation of power in three-phase systems is fundamental for electrical engineers and technicians, particularly in industrial and commercial settings. Accurate power measurement is critical for load balancing, energy auditing, and preventing equipment overload. Historically, these calculations were performed manually using formulas, but modern calculators automate the process, improving accuracy and efficiency. This has led to better energy management and cost control across various applications.
