Earth fault monitoring or Residual Current Monitor (RCM) plays an increasingly important role in today's applications, with their strict requirements on high energy quality and availability.
Potential applications can be found in almost every market segment. Sensitive processes with strict requirements on energy quality and availability can be found in areas such as data centres, hospitals and semiconductor plants. In combination with other electric parameters such as voltages, currents and outputs, this provides a good impression of conditions/// in the local grid.
In electric networks, from industrial grids to office buildings, interferences occur when electrical and electronic loads are used. Network interference arises when the original, "pure" voltage or current sine shape changes.
