Power quality is important for everyone
The reason for this lies with the consumers, since their utilization of energy has an influence on the power quality. Devices such as frequency converters, switching power supplies, and other power electronics can, in some cases, cause large harmonic oscillations. These devices are used more and more frequently, as electronics have spread to almost all areas of business. Harmonic oscillations result in additional voltage in the network. In the past decade, power quality decreased worldwide, almost unnoticed by the public. The consequences are unspecific, which is why affected parties often do not realize that the problem is due to poor power quality. In fact, energy quality is a strategic issue for companies. The consequences can often be extremely expensive for system operators. Typical effects in companies and public institutions include:
- Overheated motors and lines
- Energy losses resulting from harmonic content and reactive power
- Increased wear on power packs and other components
- Device and system failures
- Computer and network failures
- Lines and networks that cannot be fully used
- High energy costs for no apparent reason
- Quality problems due to disturbed electronic controls
COMPANIES MUST TAKE ACTION !
- Ensure the operational reliability of all systems
- Ensure compliance with standards
- Better use of existing networks
