The external Residual Current Sensors are available in 500:1, 1000:1, 2000:1 and 10.000:1 ratio and are limited for the output voltage to max. 27 Vrms. High voltages in the case of loose or broken wires are thus avoided. The Current Sensor measures the residual ground fault current according to the Core Balance principle, in that all the current carrying conductors, including the Neutral wire, are fed through the sensor. Normal Core Balance Transformers are made from 2 possible metal groups, mu-metal or Silicon Iron and have an as low as possible winding count to make sure that a high amplification factor is maintained. Both metals have their drawbacks:
Modern electronics, with some precautions, can overcome the standard problems with Silicon-Iron materials. The drawbacks of mu-metals are material related and cannot be handled by electronics and are most dangerous to use due to lock-up and low temperature behaviour.
Our state-of-the-art Ground Fault protection devices consisting of Silicon-Iron core material with a small cross-section area to save material and highly integrated electronics makes it possible to have an accurate trip current range from 30 mA to 60 A and a Short Circuit detection of over 160 A using one and the same Current Sensor.
These sensors are compatible with all ground fault relays produced by GFS: DGF7-types, DGF10, DGF100, GFU20 and GFU21.
