RDZ-3
Load resistors dedicated for energy meters circuits
Modern energy meters characterises very low burden of measuring inputs. On the other hand current or voltage transformer works properly if its secondary winding burden lays between 25 - 100% of its rated output. In case of old type transformers the situation of not enough burden can occur. Load resistors RDZ-3 are installed in order to add extra load of secondary winding of current or voltage transformer. The RDZ-3 resistors can be also applied in order to eliminate ferro-resonance phenomena. RDZ-3 resistors are able to work in outdoor metering cabinets of ingress protection degree min. IP 40.

Product description

Construction

Particular resistive components of RDZ-3 resistors set are made in thick-film technology which allows to reduce inductance. Resistors are very reliable, they withstand high temperature conditions and pulse loads. Load resistors set contains three resistors (for three phase network) enclosured in special purpose casing with lock for industrial purposes and possibility of sealing. The resistors are connected to measuring circuit with terminal block type UK5 TWIN of Phoenix Contact. The terminal can be configured for Y or delta connection.
