This simulation demonstrates how differential protection works by comparing currents on both sides of a protected zone. Adjust the sliders to see how the protection responds to different current conditions.
Status: Normal Operation
Operating Current (|I1-I2|): 0 | Restraining Current (|I1|+|I2|): 8
Differential Current for Status: 0
Differential protection is a fundamental protection scheme used in power systems to detect faults within a protected zone. It works by comparing the currents entering and leaving the protected element (such as a transformer, generator, or bus).
Key Principles:
Restraint and Trip Curves: The characteristic curve shown in the plot represents the threshold between normal operation and trip conditions. Points below the curve represent normal operation, while points above the curve indicate a fault condition that would trigger the relay.
