2) Leakage Current Measurement

(1) Leakage current measurement at grounding line. The operation is the same

manner as line current measurement.

(2) Leakage current measurement except for grounding line clamp CT to two wires at

single phase and three wires at three phase in a lump.

3) Phase Current Measurement of Hi-Voltage Circuit (with shielded grounding line)

(1) Measurement of CVT Cable

In case of CVT cable as the right drawing, this

instrument can measure phase current by

clamping 1/2 CT to one phase.

CAUTION FOR MEASUREMENT



The measurement by this mode is for estimated

value detection and use it to judge circuit condition

with no loading or loading

△

WARNING



This instrument is for low voltage circuit and never

use for hi-voltage cable without shielding.
