The power utilities business is changing globally. Where once the main provides of electrical power were coal, gas, oil and nuclear power stations, today renewable sources of power, such as wind and solar are becoming significant. This is driving huge changes in all aspects of the electrical power industry, including new power quality and metering challenges requesting a new current measurement approach.
Basics Zero-Flux Technology
The Zero-flux principle was discovered in the 1980s and used for air gap magnetometers. The First Zero-flux DCCTs were built in the 1960s by the Danish company DANFYSIK, amongst others. Today, the technology facilitates highly accurate current measurements from DC up to the megahertz range. Likewise, a few mA up to 40 kA can be measured with highest precision, accuracy and stability. The basic measurement principles are explained in this whitepaper.
