The power supply is not stable and causes a number of problems, which are described below:

Power Outages (Blackout)
It is the total loss of electricity supply. It can be caused by various events; lightning, power line failures, excessive demands, accidents and natural disasters. Interference generated by loads such as lifts, lifts. Cranes, arc welding equipment, speed equipment… Human error, accidents on power lines, connection interruptions, short circuits, acts of sabotage, etc. can cause damage to electronic equipment (hardware), loss of data, or total system shutdown. Translated with (free version)

Momentary voltage dips or microbursts (Sag)
It is the momentary voltage drop, generated by the starting of large loads, starting of heavy machinery, equipment failure. It occurs similarly to blackouts but in repetitive waves. Momentary voltage dips can mainly cause hardware damage and data loss.

Voltage Spikes or Momentary High Voltage (Surge)
Peaks can be produced by a rapid reduction of loads, when heavy equipment is switched off, by voltages going above 110 % of nominal. The results may be irreversible damage to the hardware.

Undervoltage (Undervoltage)
Sustained low voltage on the line for long periods of a few minutes, hours or even days. They may be caused by an intentional reduction in voltage to conserve energy during periods of peak demand. Sustained low voltage can mainly cause damage to the hardware.

Overvoltage (Overvoltage)
Over voltage on the line for long periods. It can be caused by lightning and can increase the line voltage up to 6000 volts in excess. Overvoltage almost always results in data loss and hardware damage.

Electrical Noise (Line Noise)
Means high frequency interference caused by RFI or EMI. They can be caused by interference from transmitters, welding machines, printers, lightning, etc. Introduces errors in programs and files, as well as damage to electronic components.

Frequency Variation (Frequency Variation)
Refers to a change in frequency stability. Result of a generator or small co-generation sites being charged or discharged. Frequency variation can cause erratic equipment operation, loss of information, system crashes and equipment damage.

Switching Transient (Switching Transient)
It is the instantaneous voltage drop in the nanosecond range. The normal duration is shorter than a peak. It can cause strange computer behaviour and places stress on electronic components, making them prone to premature failure.

Harmonic Distortion
It is distortion of the normal waveform. It is caused by non-linear loads connected to the same network as critical equipment, computers and/or applications. Motors, copiers, fax machines, etc. These are examples of non-linear loads. It can cause computer overheating, communication errors and hardware damage.

And this poor supply of electricity results in the impact on the profits of companies, as they are not able to make a profit:

  • They generate losses
    Electrical problems disrupt business continuity, causing significant losses to companies.
  • Affects productivity
    Company outages affect productivity and revenue generation.
  • Destroy information
    A variation in power flow can damage confidential data, daily operating documents, statistics and financial information.
  • Damage to infrastructure
    Every variation in voltage decreases the lifetime of: personal computers, servers, machine controls, workstations and computer networks among others.
  • They generate stress
    The constant interruptions in the continuity of work and the consequent drop in productivity generate stress and demotivation in human resources.
