Cable identification: It is designed for power cable engineers and cable workers to solve technical problems of cable identification. Can be used to identify live cables and outage cables. Users can use the instrument to accurately identify a target cable among multiple cables to avoid serious accidents caused by accidentally sawing live cables. When identifying cables, 10 cables can be pre-calibrated at the transmitting end and then received and identified at the remote end, which greatly saves engineering personnel time for round-trip calibration operations and improves work efficiency. If the cable identification is successful, it will be marked as √, and if the non-target cable is marked as ×, the target cable can be quickly and automatically identified. This function is implemented by the signal transmitter, receiver, signal transmitter clamp, connecting test wire, flexible caliper and stethoscope. The stethoscope can be used when calipers are not convenient.
Pipeline ground fault finding (optional function): It can accurately locate ground insulation faults in directly buried power cables, directly buried communication cables, directly buried optical cables, etc. When the traditional high-voltage flashover method is applied to ground faults of directly buried cables, since the discharge energy at the single-phase metallic ground fault point is proportional to the square of the discharge current and the ground resistance, the discharge sound when the fault point penetrates the gap is relatively soft. It is impossible to accurately locate, and even in most noisy outdoor situations, it is impossible to accurately capture sound waves, resulting in impossible positioning. The cable ground fault location is based on path detection instruments and A-frames, and the step voltage method is used for measurement. The results are stable, easy to use, and the location is accurate. It can accurately detect ground faults in directly buried cables in multiple scenarios. , with arrow direction indication.
Ground resistance test: Use the precision 4-wire method to measure the ground resistance on site, and introduce FFT (Fast Fourier Transform) technology and AFC (Automatic Frequency Control) technology to automatically identify interference and select the measurement frequency to minimize the impact of interference. The maximum rated output current is 6mA, and the measurement range is 0.001Ω~2000Ω. The function is realized by the cooperation of the receiver and the connecting test line.
Insulation resistance test: specially used for insulation testing in the laboratory or on site. It is suitable for measuring the resistance value of various insulating materials such as the insulation resistance of transformers, motors, cables and electrical equipment. Embedded high-precision microcurrent measurement system, digital boost system, automatic discharge circuit, etc. The rated output test voltage range is 100V~2500V, and the insulation resistance measurement range is 0.01MΩ~2.50TΩ. The function is realized by the signal transmitter and the connecting test line.
Signal transmitter: used for pipeline path detection, cable identification and insulation resistance testing. This device can add identification signals to the target cable through direct output, caliper coupling, induction method, etc. The signals include 577Hz, 640Hz, 1280Hz, 2.56kHz, 3.20kHz, 4.09kHz, 8.19kHz, 10kHz, 33kHz, 66kHz, A total of 12 different pulse signals are available, 82kHz and 201kHz. The maximum signal output power is 10W, adjustable in 10 levels, adapting to different application environments, making pipeline detection and cable identification more accurate and reliable. The instrument has a built-in high-power rechargeable lithium battery, automatic impedance matching, and fully automatic protection. The transmitter adopts an integrated special tool box design. The box can withstand about 200kg of pressure. The host has a 5.4-inch color LCD display that dynamically displays the signal output status and battery usage in real time.
Launch clamp: suitable for caliper coupling method. The transmitting clamp couples the signal from the transmitter to the target cable. The clamp size is Φ150mm. The transmitting clamp is directional. The transmitting signal flows in from the direction indicated by the arrow on the transmitting clamp.
Receiver: used for pipeline path detection, cable identification and ground resistance testing. Built-in multiple shielded 3D antennas, which can detect 577Hz, 640Hz, 1280Hz, 2.56kHz, 3.20kHz, 4.09kHz,
8. A total of 12 different pulse coded current signals of 19kHz, 10kHz, 33kHz, 66kHz, 82kHz and 201kHz can be effectively identified. It can also identify 50Hz and 250Hz power frequency signals and radio frequency signals with center frequencies of 33kHz and 82kHz. Using a 3.5-inch color LCD screen, it dynamically displays 360° all-round pipeline path indication, depth, current and relative position of the pipeline in real time.
A-frame (optional accessory): A-shaped voltage signal sensor designed for locating ground faults in directly buried cables. The two probes or probe coils on the A-frame can accurately receive the step voltage signal transmitted from the transmitter. After being transmitted to the receiver for data analysis, the cable ground fault point can be accurately located. The probe or probe coil is designed to be independent and interchangeable. The probe is suitable for soil floors and the probe coil is suitable for cement pavements that cannot be directly inserted into the earth. The A-frame lead wire is designed with an aviation socket, which can be connected to the receiver with the aviation plug cable. It can be disassembled at will and is compatible with independently designed handles, allowing the A-frame to work independently for other functions.
Flexible current clamp: for cable identification. This current clamp is a Rogowski coil, which has excellent transient tracking ability and can quickly identify the pulse width frequency signal generated by the transmitter. It is suitable for thick cables or irregularly shaped conductors. The inner diameter of its jaws is about 200mm, and it can clamp cables below Φ200mm without disconnecting the circuit under test. The measurement is non-contact, safe and fast.
Stethoscope: for cable identification. Similar in shape to a mouse, it can quickly sense and identify current signals in transmitters or cables. The arc-shaped sensor design fully fits the surface of the cable. With the transmitter and receiver of this product, most functions of the flexible current clamp can be realized, and it can replace the flexible current clamp for cable identification in most occasions. When in use, just place the stethoscope close to the cable under test along the direction of the cable. It is suitable for testing situations where it is inconvenient to use flexible current clamps.
Special reminder: When identifying power-off cables, it is strictly prohibited to connect them to live cables. Live cable identification is only applicable to three-core armored cables. During identification, transmitting clamps and receiving clamps cannot be mixed, and the direction of the input signal must be consistent.
