Below, we will analyze in detail the impact and possible causes of each type of power problem
1.①Lightning ESD、 Switching and troubleshooting of power supply faults may result in transient phenomena such as transient pulses, which may cause data loss/damage and system shutdown;
② Switching between inductive or capacitive loads may result in transient oscillations, which may cause data loss/damage.
2. ① Rectifiers or power supply failures may result in DC bias, causing transformer heating, ground fault currents, and annoying tripping;
② Nonlinear electronic loads may generate harmonics, causing transformer heating and system shutdown. For details, please refer to “Harmonic Hazards in Power Grids”;
③ Harmonic waves may occur in control signals, faulty equipment, frequency converters, frequency converters, induction motors, and arc devices, causing light flickering, heating, and communication interference;
④ The variable speed transmission device, arc welding machine, and dimmer may have burrs, causing system shutdown and data loss;
⑤ Radio transmitters, faulty equipment, unreliable grounding, and proximity to EMI/RFI sources may cause noise, resulting in system shutdown and data loss.
3. Unreliable grounding, proximity to EM/RFI sources, radio transmitters, and faulty equipment may cause voltage fluctuations, resulting in system shutdown and data loss.
4. Intermittent operation of load equipment may cause frequency jitter, resulting in system shutdown and flashing lights.
5. ① Voltage sag may occur during load startup and faults, resulting in system shutdown, data loss, and downtime:
② Mains power failure and load changes may result in undervoltage, causing system shutdown, data loss, and downtime.
6. ① Load changes and mains power failures may cause temporary voltage surges, resulting in annoying tripping, equipment damage/shortened lifespan;
② Load changes and mains power failures may result in overvoltage, causing equipment damage/shortened lifespan.
7. Power interruption may occur due to switch switching, mains power failure, circuit breaker tripping, and component failure, resulting in downtime, data loss/damage.
The widespread use of electronic products has aroused people’s attention to power quality and its impact on key electronic devices used by enterprises. Especially with the increasing integration of data centers, they rely more and more on small microprocessors, which are very sensitive to small power fluctuations. Automated mechanical equipment is usually controlled by microprocessors and packaging production lines that cannot be shut down. The simplest way is to use UPS power supply to limit or eliminate the impact of power quality disturbances. Regardless of the size of the enterprise, its goal is to shorten equipment downtime, reduce production costs, and increase profits. By using APC UPS to ensure the quality of equipment power supply, it will help find better ways to achieve business goals.
