What are the common power problems?

In an ideal world, your wall socket would provide an infinite supply of perfect power, at constant voltage and cycle exactly once per second. Don't bet on it. The following are some of the most common electrical power issues and the UPS solutions that address them:

Power Failure

This complete interruption of the electrical supply, also known as a blackout, can be caused by a variety of factors such as utility equipment failures, storms, objects striking lines or poles, fire, and human error. Damage to equipment and data loss are common outcomes.

Power Sag

This sudden drop in normal voltage level frequently causes serious equipment malfunctions and is usually caused by transmission or distribution network faults, the connection of heavy loads, or the start-up of large motors.

Power Surge

Lightning, line or capacitor switching, and the disconnection of heavy loads cause these extremely fast voltage variations. They damage electronic components, causing data processing errors, data loss, and electromagnetic interference.

Undervoltage

This voltage drop, also known as a brownout, typically lasts a few minutes to a few hours and is usually caused by over demand or intentional "throttling" of electricity during peak demand. It has the potential to damage computers and other electronic devices.

Overvoltage

Data loss, screen flickering, and equipment damage are some of the consequences of these momentary voltage increases, which are typically caused by heavy load starting/stopping, poorly dimensioned power sources and poorly regulated transformers.

Line Noise

These superimposed high-frequency signals on the waveform are most often caused by electromagnetic interference or improper grounding, resulting in disturbances to sensitive electronic equipment, data loss, and data processing errors.

Frequency Variation

The most common cause of a loss of stability in a power supply's normal frequency of 50 Hz or 60 Hz is heavily loaded generators. Because of the issue, motors may run faster or slower, resulting in inefficiency, excess heat, and degradation.

Switching Transient

These transient voltages or current changes that can damage equipment are caused by lightning, switching of loads and capacitor banks, opening and closing of disconnects on energised lines, re-closure operations, and transformer tap changing.

Harmonic Distortion

This distortion of the normal power wave is typically transmitted by unequal loads and can cause resonance, overload, and overheating of cables and equipment, among other issues.
