IG Transformers Series
Model: TOROIDAL RESIDUAL CURRENT TRANSFORMERS Series
The Series IGT range is 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 50 to 400Hz. Maximum ambient temperature +70 degreesC. The lower earth current sensitivity limit is in the region of 3 to 5mA.
The recommended maximum distance between a residual current transformer and the Earth Current Monitoring Unit is generally 100meters. If the distance exceeds 5meters, or the connecting cable is exposed to heavy stray electromagnetic fields, the cable (minimum 0,4sqmm) should be shielded. The shield should be grounded to protective earth (PE) at the end closest only to the monitoring unit.
