LV Toroidal Transformers – CT1/CTD1


The toroidal transformer is installed between the source and the load. The system works on the current balance principle. In a correct installation the vector sum of the currents is zero and the relay will not trip.
 
In case of an insulation fault on the circuit a leakage current flows to earth. Now the vector sum of the current passing through the transformer is not zero, this imbalance is detected by the transformer, which induces a current in the secondary winding which is connected to the relay.
 
Earth Leakage Protection & Measurement Transformers for Low Voltage
 
  • To be used with ELR-B, ELR-3C, D30 and DM30 relays.
  • The transformer and relay assembly sensitivity is fixed by the relay.
  • The toroidal transformer CTD-1/28 is specifically designed for DIN rail mounting.
