HIGH VOLTAGE (22KV) CLAMPMETER
High Voltage Clampmeter is connected with insulation rod, which can be used for
measuring current at high voltage that is upto 22KV, on-line current measurement,
Model KM 8000
also having peak measurement,data storage, and other functions, and its specialy
designed clamp makes it easier for clamping the testing wire by pressing or pulling
back the insulation rod, time-saving and fast, widely used in transformer substation,

N
power plant, industrial and mining enterprises as well as the inspection station and
electrician maintenance departments for electrical current detection and field
electrical operations. It can also replace the H. V. Transforming ratio tester, that is to
detect the high & low current for primary circuit and secondary circuit separately.
The insulation rod is light and convenient, with the advantages of anti-moisture, high
temperature resistance, anti-impact, bending resistance, high insulation, flexibility
and other characteristics.
SPECIAL FEATURES :
?
High Voltage AC Current Measurement.
?
Leakage Current Measurement.
?
Low Voltage AC Current Measurement.
?
On-Line AC Current Supervision.
