Description
CTG is a family of “core balance transformers”.
These devices detect the difference in the current flow on the lines running through the coil.
They work on either single phase or three-phase mains.
When the vectorial sum of the current flowing to the load and the one flowing on the NEUTRAL cable (if present) is different from “0” (zero), a current on the CT secondary circuit is generated.
The current difference is usually caused by a leak which may cause an hazard.
The output signal can be used by a residual current monitoring device which will disconnect the monitored load or send an alarm signal.
Benefits
• High sensisitivity.
• Wide range.
• Easy installation.
