H Tinsley has introduced the 5762N high resistance fault locator.
H Tinsley has introduced the 5762N high resistance fault locator.
It is claimed it can be used in the factory to find faults in stock cable or in the field to locate faults in an installed system, including underground cables and can be mains or battery powered.
The portable instrument will find the position of a single shorting fault between two conductors, or between one conductor and the cable sheath or ground.
A fault is located by a manually adjusted potentiometer in combination with a bridge circuit to pinpoint the fault as a percentage of the cable length.
Faults up to 200 MOhms can be found and accuracy is 0.5 percent, which equates to tracing a fault to within just a few inches in a cable run of several hundred feet claimed Tinsley.
The instrument is housed in a visible moulded case that is rated to IP67 when closed.
A rechargeable battery is included.
