An interactive tool for analyzing three-phase power systems
A mathematical technique that transforms complex three-phase power systems into simple, balanced components for easier analysis and system design.
Three equal magnitude phasors, separated by 120° intervals, rotating in the normal phase sequence (A-B-C). Represents the balanced portion of the system that generates useful torque.
Three equal magnitude phasors, separated by 120° intervals, rotating in the reverse phase sequence (A-C-B). Creates opposing torque and indicates system imbalance.
Three equal magnitude phasors aligned in phase (0° separation). Indicates ground faults and would not exist in a perfectly balanced three-phase system.
Enables precise diagnosis of different fault types in power systems.
Allows for designing relay systems that respond appropriately to faults.
Quantifies the degree of asymmetry in power systems for correction.
Simulates behavior under various unbalanced conditions.
