Description
IGTx & IGRx series are used as sensor to detect earth
leakage current in Megacon Earth Fault Systems for selective monitoring
and protection.
The transformers measuring accuracy and repeatability is high and is not
influenced by the relative position of the individual conductor passing
through the transformer core.
Nominal measuring range is 40 to 70Hz. Maximum ambient temperature +70 °C.
The lower earth current sensitivity limit is in the region of 3 to 5 mA for the IGTx series and 5-10mA for the IGRx series.
The recommended maximum distance between a residual current
transformer and the Earth Current Monitoring Unit is generally 50meters.
If the distance exceeds 3meters, or the connecting cable is exposed to
heavy stray electromagnetic fields, the cable (minimum 1mm²) should be
shielded.
The shield should be grounded to protective earth (PE) only at the end closest to the monitoring unit.
