Characteristics of Underground Pipeline Detector
Most of the underground pipelines are metal materials, which can induce and transmit electromagnetic waves. With its superior performance and flexible and convenient detection methods, the underground pipeline detector has a large number of users in the fields of electric power, telecommunications, water supply, heat, gas, petroleum, chemical industry, urban public utilities and so on, It has played a positive role in improving the pipeline management level of relevant industries in China. The underground pipeline detector is characterized by multi-functional measurement and simple operation. Stable performance, full digital control, sufficient power, long continuous use time, portable design, suitable for field operation. Under the condition of no excavation, it can not only accurately measure the position of buried pipeline, but also accurately locate the damaged point. Even pipelines with branch pipes or forming a network can be effectively detected. Thus, the pipeline network diagram of * * is drawn, which provides strong support for urban construction and pipeline maintenance. Auxiliary functions of underground pipeline detector 1. Automatic adjustment of receiving gain: automatically adjust the gain of the receiver to make the receiver in an optimized state, avoiding the tedious manual adjustment. 2. Sound function: the tone change sent by the receiver through the horn directly reflects the measured signal size. 3. Pipeline state detection: when the transmitter is in injection mode, first detect the insulation resistance and residual voltage of the pipeline, and then apply the signal to the target pipeline. When the insulation resistance on the pipeline is small (close to short circuit to ground), the transmitter will automatically exit this mode. When the residual voltage is large, the transmitter will give an alarm, and the operator shall immediately stop loading the signal and turn off the transmitter. 4. Battery power detection: real-time detection of battery power. When the power is low to the protection value, an alarm will be sent out and the battery will be shut down automatically. 5. Power saving function: after the transmitter is turned on for about 30 seconds without pressing other keys, and after the receiver is turned on, if other keys are not pressed for about 10 minutes, the machine will shut down automatically to save battery power.

What Should Be Considered When Purchasing a Cable Fault Tester
What Should Be Considered When Purchasing a Cable Fault Tester
Cable fault tester is a common cable fault detection equipment, and its accuracy and detection speed are guaranteed. We are used to evaluating this thing before we buy it, from its performance, value, price and other aspects. After that, we will decide whether to buy it. So, what evaluation should be done when purchasing a cable fault tester? When selecting the cable fault tester, the cable fault tester needs to understand its performance. Is its overall performance stable, or is it convenient in the whole operation? If there are problems in the operation and unstable performance of the cable fault tester you choose, it will certainly lead to more problems in the whole use, not to mention that the cable fault tester you choose is a test suitable for your own use, which can not highlight its whole use value. Therefore, when selecting the cable fault tester, we should pay attention to these two points: 1. How about the performance? Before choosing a cable fault tester, you'd better understand and test several different cable fault testers, that is, find some early tests to see if they really have high usability. 2. Quickly detect the fault point and find the problem of your own equipment in a very short time, If you can, it can show that it is a very good cable fault test. If you can't meet this standard, you will waste more time and money, and the selected cable fault tester will not be suitable for your own use. Therefore, we can understand how to select a more appropriate cable fault tester. After selecting an efficient and suitable cable fault tester, the next step is how to use it. What if you can better operate the cable fault tester to enable you to quickly detect the fault point? 1. Understand the instructions of the cable fault tester. After you get a cable fault tester, you need to understand its operating instructions before preparing for operation. Some people feel that they have a certain understanding of the cable, so it is not necessary to understand its operating instructions when using it. In fact, this is not the case, Most of the time, my knowledge is very different from professional operation, so I can understand the contents of the operation manual in advance before use, which naturally has a very good guarantee for the whole operation after use. 2. Check the circuit. When using the cable fault tester, do you need to test in advance or find out if there is a problem with its circuit connection? If there is a problem that needs troubleshooting, you also need to know whether the whole connection is normal in advance, so as to have higher detection efficiency in the whole detection, know the problem of cable fault, and find a good solution, so as to ensure the working performance of the whole power system. Generally speaking, after the carefully selected cable fault tester, the equipment performance of the cable fault tester is guaranteed. In the process of cable fault detection, the corresponding fault results can be obtained according to the fault performance in the operation manual.
The Benefits of Using the Right Non Contact Voltage Tester
The Benefits of Using the Right Non Contact Voltage Tester
You hear continuous chirping and see a series of flashes confirming that the tester has detected the voltage. This type of voltage tester allows you to test voltage without having to open or splice wires. This tool can also be used to dim the basement in situations where the light does not work, a small but helpful feature as it is the only model we have tested.In fact, the mere presence of an electric field can trigger this type of voltage tester. Non-contact voltage testers work by measuring a small amount of current coupled to the circuit between the tester and ground. Since they are light, they can detect this current without direct contact.A contactless tester is a device which allows the user to check the voltage of a variety of electrical appliances without touching wires or parts. The functioning of these devices is based on the use of capacitor couplings to detect electric fields. The built-in sensors at the top of the tester detect the presence of voltage without touching the conductor, socket or power cable.Volt sticks are designed for a specific purpose: to detect the presence of AC voltage. The electric fields connected to the AC voltage are present in the current conductor, and the reason for this is the requirement of direct contact with the conductor. Another reason is that electric fields have to build up and collapse in order to induce a current in the volt rod circuit, which happens with alternating voltages.If you refer to the capacitors in the video above, you can see that the current flows at an AC voltage. With a DC voltage, the electric field must build up and remain in one direction until a current is induced in the voltage stick circuit, and since there is no volt stick in the circuit it does not indicate the presence of a DC voltage. This is the reason why testers do not work with DC capacitors and why transformers do not work with DC voltage.A few ticker markers, including the Southwire Dual Range non-contact voltage tester can detect two voltage ranges. The higher voltage range is the default, while the lower voltage range (tension range) at the upper end is kept at 1,000 V. Most voltage testers do not register voltages below, giving Southwire a significant advantage over simpler models.Electrical testers are a good value option with impressive IP67 water resistance. Mid-range models such as the SouthWire non-contact voltage tester are designed to withstand the elements. If you need an outdoor quality tester, you will appreciate the IP67 waterproof housing of these pins.The Small Non-Contact Voltage Tester (NCVT) is ideal for NCVT electricians working with HVAC, ventilation and air conditioning systems (HVAC). Not only is it the most reliable model in the price range of non-contact voltage testers, but also has the new Voltbeat technology that enables self-testing. When something goes wrong the problem can be detected by the sensor or from a device such as a nearby voltmeter or oscilloscope.
Working Principle of Cable Identification Instrument
Working Principle of Cable Identification Instrument
The working principle of the cable identification instrument needs to add a special signal to the identified cable, which should be received by a special receiver. Using this characteristic, the cable to be found can be identified. The cable identification instrument works according to the following principles: the cable identification instrument consists of a signal generator, a receiving clamp signal detector and an indicator. The signal generator mainly generates special pulse modulation signals, which are added to the stopped tested cable through the output line. The receiving clamp is used to find the tested cable on site. When the receiving clamp detector detects the special signal applied to the cable, The electric meter pointer on the signal detector swings synchronously with the frequency of the applied signal, while the signals detected on other cable lines are much smaller and in the opposite direction. It is easy to determine the tested cable by indicating the amplitude and direction of the electric meter. When the receiving clamp signal detector is used in combination with the signal generator, it can be used to distinguish the charged state of the cable, or assist in finding the short circuit position of the cable. When receiving clamp signal detector is used, clamp the cable with clamp.

Analyze the Problems That May Be Encountered in the Fault Detection of Pipeline Detector
Pipeline detector is one of the important equipment for underground pipeline survey. It can accurately and quickly detect the direction and location of various underground facilities under the condition of ensuring the integrity of ground covering soil. What we want to know today is the purchase method of the detector and some problems that may be encountered in the fault detection of the pipeline detector. You can study it carefully. The pipeline detector can quickly and accurately detect the position, direction and depth of underground water pipeline, metal pipeline and cable, as well as the position and size of the damage point of the anti-corrosion coating of steel pipeline without damaging the ground covering soil. It is one of the necessary instruments for water supply companies, gas companies, railway communications, municipal construction, industrial and mining, capital construction units to transform, maintain and survey underground pipelines. How to choose a pipeline detector? Here, I share my views with you, hoping to be helpful to you. 1. According to your own needs: many pipeline instruments are only suitable for some detection requirements. When selecting, you should understand the application scope of pipeline instruments. 2. Understand the test method of the pipeline instrument, whether the operation is simpler and the interface is more intuitive. 3. Understand the function of the pipeline instrument and whether the sounding capacity meets your needs. 4. Whether the configuration of accessories is complete, such as clamp (generally used for cable detection in dense areas), rechargeable battery (saving detection cost), etc. 5. The sustainable development of the instrument and the ever-changing technology are also a test standard of the instrument. 6. The compatibility of the instrument, whether the reception and transmission frequencies are wide, which is conducive to detection and expansion of use. In urban construction, urban underground pipeline data is very important. Pipeline detector manufacturers understand that many underground pipelines are troubled by aging and drawing changes during construction. At present, the detection work has been carried out in an all-round way. With the help of pipeline detector, supervise the whole process of project quality, project progress, operation safety and achievement archiving of underground pipeline detection. After the general survey, the results table will be prepared, the data function of the pipeline detector will be used, and the database and underground pipeline information management system will be established. It is a common situation for us to carry out detection in the completed area, which is a common problem in the fault detection of pipeline detector. For example, the general urban exploration work will encounter the interference of many urban buildings. At this time, it is necessary to rely on the sensing function of the pipeline detector for underground exploration. In the completed area, the operation procedure of the pipeline detector is: first, use the geophysical method to detect the category pipe diameter of each pipeline or the items of the inner bottom, upper pipe and outer top of the cross-section pipe (ditch) on the spot, and mark each characteristic point on the spot, then use the total station or RTK to measure the three-dimensional coordinates of each characteristic point, and then use the mapping software to draw the collected data on the topographic map for editing.
Take Measures to Prevent Cable Failure
Take Measures to Prevent Cable Failure
According to the cause analysis of insulation, accessories and outer sheath faults, it can be seen that the cable line project is a systematic project. Only by managing the whole process from the aspects of design, construction, operation and maintenance can its safe operation be guaranteed to the greatest extent. (1) From the beginning of the design, the grounding system used by the cable shall be fully understood, and the cable conforming to its voltage level shall be selected to avoid the cable working under long-term overvoltage. The selection of outer sheath shall meet the requirements of service environment and service life. At the same time, the selection of cable sheath protector shall meet the principle that the protector can reliably pass through the grounding current without damage during relative grounding. (2) The selection of cable route shall avoid the influence of external environment such as overheating, corrosion and external force damage on the cable. At the same time, it shall also avoid the influence of internal factors causing overheating due to too concentrated cable laying, resulting in the failure of timely diffusion of heat. In addition, the cable path of double circuit power supply is not recommended to be laid in the pipeline of the same path to prevent simultaneous damage and large-area power failure. (3) Strengthen the selection of cables and cable accessories, manufacturer supervision, arrival acceptance and other work to ensure the quality level of cables and cable accessories. During the on-site inspection, the manufacturer, the construction party, the supervisor and the project competent department shall be present, check one by one according to the packing list, timely record the problems found and put forward rectification suggestions, which shall be signed and approved by many parties. After the inspection, the parts susceptible to moisture shall be sealed in time to prevent moisture from affecting normal use. (4) Strengthen personnel training, conduct necessary business qualification and technical evaluation for cable head fabrication personnel, and work with certificates. In case of two consecutive failures due to manufacturing reasons within the warranty period, the cable head manufacturing qualification shall be cancelled, and it can be re employed only after passing the re training and assessment. (5) Strengthen the acceptance of concealed works and intermediate links in all links of cable engineering, strictly control the quality acceptance, thoroughly rectify the defects and hidden dangers found in the acceptance of civil engineering, electrical and other projects, make various records, and leave photos, films and other materials if necessary. (6) Advanced on-line monitoring technologies such as outer sheath circulation on-line monitoring technology, on-line optical fiber temperature measurement technology and on-line partial discharge detection technology are used to strengthen the real-time on-line operation monitoring of cables, find hidden defects in advance and avoid power failure.
