3.5.3. VOLTAGE MEASUREMENT AND CURRENT CONNECTION
The CDP measures current using the MC1 or MC3 transformers with a
secondary current of 250 mA
Table 9: Current measurement transformer models.
Transformer models
MC3 – three-phase
transformer
MC1- 1 transformer per phase
Models 63, 125 and 250 A.
Models:
150/200/250A, 250/400/500A,
50/100/150A, 500/1000/1500A,
1000/1500/2000 A
Each transformer has 3 ratio ranges,
changing a connection cable and the
chosen ratio in the measuring unit.
