KEW LEAKAGE CLAMP METERS
Broadly speaking, there are two methods of leakage current measurement. One is designed to measure leakage current by directly
clamping on an earthing conductor and the other is intended to
measure leakage current by clamping on two-way wires together.
Please refer to Fig.1 for respective measurement methods. The
principle of measurement involving the clamping of two-way wires
together is meant to find out the difference of current flowing
between the incoming wire and outgoing wire and display the
result. If there is no leakage on the load side, the instrument display reads zero. If the leakage occurs on the load side, the leakage
current will flow back into the power supply through earth, resulting
in the difference of current flowing between the two-way wires
which will then be displayed on the instrument as a value of leakage current.

KEW LEAKAGE CLAMP METERS
This is a full range of our leakage clamp meters.
Use of highly sensitive transformer jaws permits AC current
measurements in the order of milliamps. These instruments
can measure not only earth leakage current but also leakage
current flowing in live conductors of single and three phase
systems by directly clamping them together.
The most outstanding feature of the Kyoritsu leakage clamp
meters is that all models have a frequency selector switch to
check for the harmonic content of the current under test.
