4.5 Connecting to the Lines to be Measured (Preparing for Current Measurement)

64

Applying current sensors to lines to be measured

OK

Example: CT7136

Source side

Line

Load side

Current flow

direction arrow

Always clamp the instrument around only one conductor. Clamping the instrument around

two or more of conductors in a bundle prevents the instrument from measuring any current
regardless of whether the measurement target is a single-phase or three-phase circuit.

Make certain that the current flow direction
arrow points toward the load.
