High-speed electrical events—like switching surges, lightning strikes, and equipment energization—can severely affect system performance and protection if not properly modeled. Electromagnetic Transient (EMT) studies simulate these fast events in microsecond detail, helping prevent insulation failure, misoperations, and equipment damage.
Models fast voltage spikes during circuit breaker operations, capacitor switching, or transformer energization—crucial for protecting insulation systems and surge arresters.
Simulates magnetizing inrush currents and nonlinear behaviors that can trip protection devices or damage transformers during energization.
Ensures that surge arresters and insulation ratings are properly matched to expected overvoltages, optimizing system safety and cost.
Uses advanced electromagnetic transient programs to model millisecond-scale behavior in complex systems with high accuracy.
While RMS (steady-state) studies show average behavior, EMT studies reveal critical sub-millisecond transients that can cause insulation stress, malfunctions, or equipment failure—especially in modern systems with sensitive electronics and fast protection.
They help prevent nuisance protection trips, insulation breakdowns, misoperations of relays during switching, and failures related to ferroresonance or transformer energization.
