Power quality has found a renewed interest in many different industries due to changing power generation modes and consumption dynamics in today’s electric infrastructure. Implementing a power quality solution comes with many challenges – for which Analog Devices provides a simple solution.
Power Quality (PQ) in the utility space largely refers to the quality of the voltage delivered to the consumer, however, by definition, it denotes both voltage and current. While the voltage is easily controlled by the generation side, the current is governed largely by consumer side usage. The concept and implications of PQ issues are rather widespread, but in general they have a large, negative economic impact on the results of many business sectors.
For many business sectors, PQ monitoring is a critical cost-saving strategy. For others, it is an activity which simply cannot be avoided. However, monitoring PQ efficiently and effectively at scale is no easy task. It involves having highly trained personnel and expensive equipment installed on multiple points all along the electric system for long or indefinite periods of time.
Analog Devices Pre-Certified IEC Class S Power Quality Solution
ADI has developed a complete solution that provides PQ measurements according to the IEC 61000-4-30 Class S standard. The ADE9430 is a highly accurate, fully integrated, polyphase energy metering IC, which significantly reduces the development time and costs for PQ monitoring products. Thanks to high accuracy and the tight integration of acquisition and calculation engines, ADI’s solution simplifies the implementation and certification of energy and PQ monitoring systems.
