1. ApplicationThe dry, siliconic rubber moulded, toroid transformers are made for fitting on 3-phase, remote controlled, exteriortype, SF-6 insulated surge arresters, together with protection devices. The transformers comply with SR EN 60044-1:2002 / A2:2003

2. SymbolizationTransformer symbolization is made using letters and numbers representing the transformer type:

CTP – 0,72: Current Transformer for Protection, maximum voltage of 0,72 kV, followed by the transformation ratio, precision power and precision class.

3.
