10 Common Power Problems
1. Power Failure
A total loss of utility power.
2. Power Sag
Short term low voltage.
3. Power Surge
Short term high voltage above 110% of nominal.
4. Undervoltage
Reduced line voltage for extended periods of a few minutes to a few days.
5. Overvoltage
Increased line voltage for extended periods of a few minutes to a few days.
6. Electrical Line Noise
High frequency waveform caused by RFI or EMI interference.
7. Frequency Variation
A change in frequency stability.
8. Switching Transient
Instantaneous undervoltage (notch) in the range of nanoseconds.
9. Harmonic Distortion
Distortion of the normal waveform generally transmitted by non-linear loads.
10. Common Mode Noise
Electrical Interference that is measured between ground and either line of an AC power line.
