The 10 Power Anomalies That Threaten Your Systems — Know What’s Affecting You

Power is an important foundation of any modern business. Despite its commonality, the quality and consistency of power can vary greatly. It’s crucial to recognize that not all power is consistent or stable, and even minor fluctuations in waveform, voltage, or frequency can have a significant impact. The initial step in protecting your business operations is to gain a thorough understanding of the different types of power issues that may arise. Whether your equipment consists of communication systems, production machinery, or sensitive data servers, they all rely on a continuous and dependable power supply to function efficiently and securely. The top ten power anomalies that can impact critical systems across various industries. Let’s delve deeper into each of these issues.

10 Common Power Anomalies You Should Know About:

1. AC Blackout: Complete utility disruptions lasting more than two cycles are referred to as AC blackouts. This type of power blackout is the most prominent and damaging. Lightning strikes, broken power lines, utility equipment failure, or planned shutdowns can all cause it. Blackouts can bring all power systems to a sudden halt, possibly destroying data, interfering with business operations, or even disrupting infrastructure that is fundamental to safety.
2. Power Sag: A short-term fall in the voltage levels is known as power sag. This is commonly seen in large equipment, such as motors and HVAC systems, creating a sudden spike of current that drops the voltage. Sages can be triggered by momentary overloads and utility switching. Even though they are a short-term dip, they still can cause voltage-sensitive device failure, flickering screens, or even unexpected system resets.
3. Voltage Surge: A voltage surge is a temporary spike in voltage that goes beyond 110% of the standard level and can last for multiple cycles. This kind of surge is mainly caused by the malfunction of the power system, lightning strikes, and switching operations. This surge can lead to circuit overload and cause permanent harm to the internal components in milliseconds; therefore, it is very dangerous for sensitive electronics components and computer equipment.
4. Burnout: A long-term drop in line voltage that can last for minutes or even several days is called burnout. Burnouts are purposefully produced by utilities in times of high demand to safeguard power. The equipment is usually stressed due to this prolonged low voltage that can cause overheating, compressor damage, poor lighting, and poor performance.
5. Overvoltage: This problem is caused by extended periods of high line volage. Issues with power distribution, transformer malfunction, or even improper setting up of utilities can lead to overvoltage. The life span of electronic systems can be reduced by prolonged exposure to higher-than-normal voltage, thereby causing overheating of the power supplies and other components.
6. Normal Mode Noise: The high- frequency electrical interference between the line (L) and the neutral (N) conductors is called the normal mode noise. These are mainly due to electromagnetic interference (EMI) or radio-frequency interference (RFI), which often originates from adjacent electronics or industrial machinery. This noise can cause issues such as communication problems, data transfer difficulty, or even odd device behavior.
7. Frequency variation: There is a standard frequency at which the electrical systems operate in North America and in other parts of the world. It’s 60 Hz in North America and 50 Hz in other countries. Variation in frequency happens when there are fluctuations due to inconsistent generation sources, such as the backup generators or unstable grids. These kinds of fluctuations can cause malfunction, desynchronization, or even overheating of sensitive devices.
8. Switching Transient: These are fast and high-voltage surges that only last for a very short period, typically microseconds. These are normally caused by sudden changes within the power system, such as lightning, inductive load interruption, or even capacitor bank switching. Transient switching can interfere with the clock process and can damage fragile circuits even though it only lasts for an instant.
9. Harmonic Distortion: A harmonic distortion is caused when the electrical waveform deviates from its ideal sine wave shape. This change is mainly caused by nonlinear loads like rectifiers, switch-mode power supplies, LED drives, and variable frequency drives (VFSs), leading to excessive heat, electrical noise, and disturbance to sensitive equipment such as motors and transformers.
10. Common Mode Noise: Common Mode noise is the interference between ground and either the line (L) or neutral (N). This can cause problems in the system that particularly depend on stable ground reference, like data centers and control systems. This can lead to communication loss, equipment lockup, and mistakes in sensitive measurement devices.
