Overvoltage in power systems
Understanding Overvoltage in Power Systems
Test your knowledge on resonance over-voltages and ferro-resonance in power systems! This quiz consists of six multiple-choice questions designed to assess your understanding of these critical concepts in electrical engineering.
- Learn about resonance over-voltages and harmonics
- Explore the effects of ferro-resonance
- Understand the implications of intermittent ground faults
Resonance over-voltages happens only for one frequency value
True
False
The presence of harmonics increases the probability to have resonance over-voltages
True
False
Ferro-resonance can happen at different frequencies
True
False
Ferro-resonance can cause infinite overvoltage in a lossless line
True
False
Intermittent ground faults can appear only in solid neutral earthed systems
True
False
In a single-phase line, the maximum overvoltage due to intermittent ground fault is 4 times the peak nominal voltage
True
False
