Voltage Regulation Calculator
Calculate voltage regulation, voltage drop, and power loss in electrical circuits and transformers. Essential for electrical engineers, technicians, and DIY enthusiasts working with AC/DC systems.
Step 1: Electrical Parameters
0.9
Standard Voltage Levels
Residential: 120V/230V. Industrial: 400V/480V. Transmission: 11kV-765kV. Power factor should be ≥0.9 for efficient systems.
Step 2: Cable & Load Specifications
5%
Optimal Voltage Regulation
For residential circuits: ≤3%. For industrial circuits: ≤5%. For transmission lines: ≤10%. Higher regulation causes voltage fluctuations and equipment issues.
