Protection relays and transformers Protection transformers Selection table of the type of transformer, in accordance with the list of transformers between the nominal current of the primary (Ip) and secondary (Is) 5 000/5 4 000/5 - There are two types of transformers: }} TRM: Measurement transformers en- CIRCUTOR offers a complete range of current transformers encapsulated in resin. One of the advantages of this type of transformers is that they increase the degree of robustness (high mechanical resistance, high electrical rigidity, tropicalization, etc.). In addition, this range fully prevents...

Protection relays and transformers the measurement unit. Induced power must be equal to or more than the line losses plus the power consumed by the measurement equipment. in measurement transformers and at 100% of the nominal power. In the case of protection transformers, only at 100% of the nominal power. The transformer's response to saturation Power losses due to the transmission of current through the cabling resistor RL of the secondary cabling circuit of the transformer. Factors that must be taken into account: }} Secondary current. PL = RL • I 2 }} Cable diameter. RL is inversely pro-...
