Description
Surge Wave Receiver SLE200-Z is a highly sensitive equipment to exactly locate the fault point in a short time. It can be used
on low, medium and high voltage power networks effectively.
The success of locating exact fault point on the underground cable depends on the search carried out on the lay of the cable.
This calls for an indication to guide the operator to walk precisely on the cable route.
Application
The SLE 200-Z Surge Wave Receiver is an easy operation device used to pinpoint the fault point. It integrated the function of
acoustic magnetic synchronization method, the step voltage method, the magnetic field strength method to make the pinpointing
accuracy.
Key Features
- Perfect functions, suitable for pin-pointing all kinds of cable faults and detect cable path.
- High accuracy
- Synchronous sensing of acoustic and magnetic signals of the fault with high ability to anti-interference.
- Waveforms displayed on large LCD
- With the assistance of the earphone, direct and easy to identify the fault.
- High Acoustic & Magnetic field sensitivity
- High Performance electronic suppression of external noise and interference
- Automatic contactless turn off of the Headset, as the hand approaches the handle
- Indication of the direction to the fault -. Compass
- Comparison of last and the new measurement
- Low batt indication.
- Graphical indication of the magnetic field
- Indication of the acoustic signal detection
- Indication of all adjustments and settings
- Fault distances measurement
- Measure of magnetic field and sound coincidence with acoustic selection and calibration of the measuring range.
- Indication of cable position in respect to the sensor.
- Cursor to identify the time of delay between the acoustic signal and the magnetic signal, thus to confirm the fault range
- Automatic switch between different work modes
- Automatic gain adjustment
- Indication of cable position in respect to the sensor
- With back light, automatic power-off and overcharge protection functions. Easy to operate
Working Principle
Acoustic magnetic synchronous pinpointing method is a
accuracy and based on traditional audio magnetic pin-pointing
method but with improvement.Traditional method use the high voltage generator to impact
the fault cable by DC high voltage to make the fault point
breakdown and discharge. The mechanical vibration from this
delivered to the earth and be collected by the sensor, which is
synchronous with the special sound.
The traditional method only use the earphone to monitor and
use the meter pointer to help to distinguish the discharging
sound. Because this discharging sound is fleeting and difficult
o distinguish from the environment noise, it common requires
rich experience user.
To modify the traditional method, we now use acoustic
magnetic synchronous pinpointing method.
Because the magnetic transmission velocity is much quicker
than the acoustic transmission velocity, It's definitive sample to
find the faulty point by testing the time difference between
magnetic signal and audio signal. Keep moving the sensor to
find the point with min. time difference, and this will be the fault
point.
Please also notice, because there's no exact data for the
acoustic velocity in the cable and have no exact data of the
cable depth, it is difficult to calculate the distance between the
sensor and the faulty point.
