HZ-B Underground Power Cable Fault Pinpointer

The HZ-B is a portable, ultra-quiet visual impact discharge receiver designed for precision fault location. It is specially developed for use in conjunction with a high-voltage impulse generator. The instrument incorporates leading technologies including background intelligent noise reduction and acoustic tracking, enabling continuous optimization and perfect sound reproduction. It records the characteristic sound of impact discharge and compares it with signals picked up on-site for accurate identification.

Technical characteristics

◆ Ultra-quiet noise reduction processing, excellent sound quality of discharge sound, the background is quieter, monitor earphones are used to quickly and reliably locate the fault location.

◆ Using ultra-quiet technology and BNR intelligent background noise reduction technology, you can adjust the impact discharge volume.

◆ Molded design of a special self-falling ground sensor, and equipped with a soft pavement, hardened pavement, lawn sensor joint.

◆ Reliable imported connectors are selected to ensure the purity of the sound, and the height-adjustable probe handle is humanized, which is very suitable.

Technical parameter:

◆ Sensor dynamic range: sound channel> 104dB.

◆ The impact discharge sound amplification factor > 90dB, and the upper limit of impact discharge volume is 84dB (A).

◆ Liquid crystal display: high-bright true color screen, 320 x 240 pixels, suitable for outdoor.

◆ Continuous working time on site: Alkaline replaceable battery, convenient for on-site use
