Cable Fault Locator (MegaSeek)
A. Introduction
MegaSeek is a device to
detect the fault points as inverted Type Murray Bridge method.
It shows excellent ability of
location in following case.
(1) Between Conductor
and shield ……. Electrical breakdown
of insulator
(2) Between Shielding
and Ground …… Poor insulation in
corrosion-poof layer
(3) Between Conductor
and Ground …. Poor insulation in
cable without Shielding
MegaSeek has two ways to locate a fault point.
One is to locate at terminals and the other is
needle-electrode method to pinpoint
a fault point along cable route in combination with the signal voltage
generator.
Two methods could be used either alone or
together.
B. Features
1. Excellent in detecting sensitivity.
The unit is capable of detecting even a faulty spot resistance
value of 1,000Kohm(1Mohm) at a detecting error of 1%.
For 10% error, a resistance value of 10Mohm can be detected.
Therefore,
work involved for carbonizing by DC current to reduce the faulty spot
resistance value becomes unnecessary.
2. Free from electric shocks
Since the unit operates on a dry battery of
only 1.5V, it is quite safe without any danger for the operator to have electric shocks.
3. Usable in the absence of external
power source
Owing to the measuring power supply
incorporated, the unit can be used in
places without any AC power sources.
4. Operative even if the cable is spaced from the operator.
Since it is not
absolutely necessary to use
particular measuring lead wires as required in the conventional bridges,
there is no
problem even when the cable to be tested
is spaced a certain distance from the operator of the unit.
5. Easy to carry about
Everything required for cable fault
detection has been accommodated in one
compact unit of MegaSeek.
Since the unit can be easily carried about by one person, it is possible
not only to save labor,
but also to effect quick
dispatch of a service man.
