Path meter parameters:
pathometer is composed of transmitter and routing receiver. This instrument is a special instrument for fault location test of low voltage cable. Its main function is to detect the cable path. Detection depth ≤ 3m; Routing error <5cm.
1) Transmitter:Output frequency: 9.82kHz
Output power: 2W
2) Routing receiver:Input frequency: 9.82kHz
Detection route error: ± 2cm
detection depth error: 5cm
battery: 9V laminated battery; Continuous operation for 8 hours
3.Fixed-point instrument parameters
ultra-quiet noise reduction, excellent discharge sound quality and quieter background. Monitor headphones
are selected to quickly and reliably point the fault point.
1) sensor dynamic range: sound channel> 104dB.
2) impulse discharge sound amplification factor> 90dB, impulse discharge volume upper limit 84dB(A).
3) LCD: highlight true color screen, pixel 320 x 240 suitable for outdoor.
4)on-site continuous working time: alkaline replaceable battery battery, convenient for on-site use
4.Integrated High Frequency and high voltage power supply for cable test
This product is mainly used for high resistance fault waveform sampling impulse discharge and impulse discharge when fault point precision is determined for power cable fault test of 35kV and below, it can also be used for burning through high resistance faults of power cables and accurate fixed-point use of the outer sheath of ultra-high voltage cables above 110kV. The burning through capability can burn through the breakdown point in a short time and reduce the resistance of the breakdown point.touch screen man-machine interaction, simple setting and operation, intuitive and convenient instrument status display;
