DGD-SD5 of cable fault fixed point instrument

After the sound and magnetic pulse signals are received, the corresponding indicator light on the fixed point instrument will light up.


Fixed point instrument

Product description

product overview

DGD-SD3 synchronous fixed point meter uses acoustic method to determine the fault point of power cable.

• Electronic flashover is generated by means of impulse discharge generator.

• The acousto-magnetic signal of the electronic flashover wave is picked up and amplified by the corresponding probe, which is judged by hearing and vision.

• After the acoustic and magnetic pulse signals are received, the corresponding indicator lights on the pointing device will light up.

• The time when the sound pulse reaches the fixed point instrument is indicated by the four-digit LCD display to indicate the distance between the fault point and the operator, so as to guide the operator to detect the fault point and finally locate the point.


Performance Parameters

Work Type: "I and II" files are used when determining the location of cable fault points; The "Ⅲ" gear cooperates with all types of "path signal generators" to detect the path of buried cables.

• It can synchronously receive sound waves and electromagnetic waves generated when the fault point is discharged.
