OPERATION AND FUNCTION INTRODUCTION
PCLD-904P support both the acoustic-magnetic synchronization pinpointing.
The acoustic-magnetic synchronization pinpointing support both intelligent pinpointing and waveform pinpointing. When use the intelligent pinpointing method, device will auto display the acoustic-magnetic delay value and when use the waveform pinpointing method, we need to make sure the cursor position and measure the delay value.
 

1. ACOUSTIC-MAGNETIC SYNCHRONIZATION INTERFACE AND FUNCTION

Principle:

Electromagnetic signal transmit by light speed and the time transmit from cable to the sensor could be ignore. The acoustic transmission speed is much lower only several hundred per second. So we can distinguish the faulty points distance by the time difference between magnetic signal and the acoustic signal.

 

There are two interfaces, intelligent pinpointing and waveform pinpointing interface when use the acoustic-magnetic pinpointing method. The intelligent pinpointing will display the acoustic-magnetic value by intelligent calculation method. It makes the pinpointing more easy and quicker, and need low requirement for the user.

Device also keep a traditional interface which more suitable for the profession staffs with experience. Then the user need to measure the acoustic-magnetic delay value by the cursor position. Refer below display interface:

 

Pictures:

Along with the low-voltage pulse reflectometry, our systems implement advanced high-voltage pre-location technologies that allow to determine the distance to faults of various types with a minimal harmful effect on the cable lines.High level of safety during the testing with our cable test vans and mobile systems is ensured by built-in protection against overcurrent, overvoltage and overheating, as well as by the use of a continuous grounding monitoring, vehicle door closure sensors and self-health check monitoring.
High speed sample system and high bandwidth input circuit are integrated in the tester to get the exact reflection curve of signal so that the distance of fault point to signal sample point can be calculated in high accuracy and high resolution Special sound location tester configuration can be applied to locate the fault point more exactly.
The cable fault tester is suitable for measuring power cables, high-frequency coaxial cables, local telephone cables, street lamp cables, low-resistance of short-circuit, open-circuit disconnection faults, and various materials of various materials with different cross-sections and different media. Leakage and high resistance flashover faults. A powerful cable management system that automatically generates test reports.
It can test a variety of 35KV under different voltage grade, different sections, different media and all kinds of material of power cable faults, including: open circuit, short circuit, low resistance, high resistance, high resistance leak flashover fault.
It can be any cable length measurement of radio wave propagation in the known speed.It can test the power cables buried path and buried depth.route tracing evaluation of electric lines and cables.
