The AC/DC meter: 0-300V; The current meter: 100mA;
In the high pressed testing equipment,
Resistance: 30±20/5kΩ;
Output resistance: 500Ω±10%.
E. Turn on the power, the screen lights. Then rise the voltage
gradually by adaptor, and when the fault point has the
phenomenon of flashover, the current in the micro-amp meter
rises heavily and the indicator in voltage meter also alters
heavily. The wave form as below should be on the screen. From
the graph, the interval of t1and t2 should be the distance of the
fault points.
F. The voltage of high voltage flashover testing method could be
as high as thousand or ten thousand voltage and operators
should obey the operation rules like connecting the equipment
to the ground and high voltage equipment’s base line and
grounding line of the equipment should connect to the cable in
lead which is connected to the ground. Connect the lines as 9.3
and check the water resistance and voltage divider resistance in
the high voltage testing.
