Here are the facts regarding power problems one through ten!
You may experience any or all these problems in your home.
1. Surges
Short term high voltage
2. Radio Frequency Interference (RFI)
High Frequency waveform – often referred to as noise.
3. ElectroMagnetic Interference (EMI)
Also a high Frequency waveform – often referred to as noise.
4. Harmonics
Distortion of the normal waveform, generally transmitted by non-linear loads.
5. Sags
Short term low voltage.
6. Brownouts
Reduced line voltage for extended periods of a few minutes to a few days.
7. Over Voltage
Increased line voltage for extended periods of a few minutes to a few days.
8. Transients
Instantaneous high voltage increase in the range of nanoseconds.
9. Blackouts
A total loss of utility power.
10.Frequency variation
A change in frequency stability.
