Figure 128: Parallel feeding of large load
Example: 2700 A current load is fed by 3 equal parallel cables. In order to measure current, we
can embrace only one cable with clamps, and select: Current transformer, Primary current: 3 A,
Secondary current: 1 A in clamp menu.
Note: During setup current range can be observed by “Measuring range: 100% (3000 A/V)” row.
Indirect current measurement
Indirect current measurement with primary current transducer is assumed if user selects 5 A current
clamps: A 1588 or A 1037. Load current is in that case measured indirectly through additional primary
current transformer.
In example below we have 100 A of primary current flowing through primary transformer with ratio 600
A : 5 A. Settings are shown in following figure.
