KDZD300C cable sheath grounding current tester is a newly developed cable current testing instrument. Through the clamp type current transformer, the cable sheath grounding current is sampled to detect various AC electrical parameters in the operation of power cables.

1. Adopt high new signal processing technology and relatively new integrated circuit components to achieve excellent test performance.
2, a variety of transmission methods of measurement signals:
(1) Injection method: used for pipelines with injection points.
(2) Clamp method: It is used for the pipeline under test with an exposed section, which is easy to clamp the pipeline.
(3) Induction method: for no injection point or no exposed pipeline.
3, a variety of measurement frequencies: there are 480Hz, 7.7KHz, 31KHz and 61KHz four active frequencies and power cable 50Hz passive frequency; Users can choose according to the different environment (if you need to use special measurement frequency, please indicate in the order contract).
4. Different positioning modes and functions to improve test efficiency:
(1) Peak mode: By measuring a large value of the signal to determine the location of the route.
(2) Valley value mode: By measuring the small value of the signal to determine the location of the route.
(3) Route orientation: indicates the direction of the route intuitively and quickly.
(4) Insulation fault search (FF): find and locate the fault point caused by the deterioration of pipeline insulation.
(5) Stethoscope: Through the stethoscope head from many pipelines to identify the signal loading pipeline.
