Power quality can be defined as the interaction of electrical power with electrical equipment. If all the equipment operates correctly and reliably without being damaged or stressed, the electrical power is of good quality. The most important parameters to technically define power quality are: • Voltage magnitude • Power • Frequency • Voltage events ( e.g.loadshedding) • Harmonics & inter-harmonics Power quality measurements and analysis are important to diagnose power system problems. Without correct and adequate measurements, these problems may be overlooked. Therefore, using high speed & accurate power quality analysis is crucial in the measurement process. The diagnosis stage needs experience on different types of load characteristics and problems. The power quality measurements are taken, and analysis is made according to the following specifications: • EN50160, • Class AIEC • NRS 048 • ENA Engineering Recommendation G5/4-1 • Latest RSA Grid Code requirements With the help of advanced measurement, analysis and simulation tools, our experienced technical team provides tailor-made solutions to our customers’ specific needs in the fields of switchgear, motor starting, power quality, reactive power compensation and harmonic filtering, analogue/digital control systems, remote monitoring, HMI systems, etc. KEY FUNCTIONS WE PROVIDE • Active harmonic filtering • Power factor correction • Voltage variation control and flicker mitigation • Load balancing in three-phase systems CUSTOMER BENEFITS • Energy savings between 25 - 40% • Reliable plant operation and reduced maintenance costs • Extended lifetime of electrical and mechanical equipment • Additional electrical capacity in existing electrical network • Compliance with G5/4, EN 50160 and other power standards and quality recommendations • Quick return on investment
