Basic Knowledge of Cable Installation
Basic Knowledge of Cable Installation
Whether the cable is installed correctly or not is directly related to our personal safety, so it is very important to learn the correct cable installation method. First of all, we need to understand the precautions for cable installation: first, when the mining cable is placed in parallel with the heating pipeline, it shall be connected with a distance of 2m, and when interleaved, it shall be connected with a distance of 0.5m. Second, when the cable is placed in parallel or interleaved with other pipelines, it shall be connected with a distance of 0.5m. 3、 When the cable is directly buried, the direct burial depth of 1-35kV cable shall not be less than 0.7m. IV. when the cables of 10kV and below are placed in parallel, the clear distance between each other shall not be less than 0.1M, 10-35kV shall not be less than 0.25m, and the distance during interleaving shall not be less than 0.5m. V. the minimum bending radius of the cable shall not be less than 15d for multi-core cable and 20d for single core cable (D is the outer diameter of the cable). 6、 Discussion on 6kV and above cables. A. When placing the cable terminal, the semi-conductive barrier layer must be stripped off. The insulation shall not be damaged during operation. Knife marks and the environment with high and low resistance shall be prevented. If necessary, it shall be polished with sandpaper; The end of the barrier shall be flat, and the graphite layer (carbon particles) shall be broken and cleaned. B. The copper barrier and steel armor at the end of plastic insulated cable must be well grounded, and this criterion should also be observed for short routes to prevent electromotive force at the end of steel armor during three-phase unbalanced operation, even ignition and burning of sheath. Tinned braided copper wire shall be adopted for grounding outgoing line. Soldering iron shall be used for soldering when it is adjacent to cable copper strip, and blowtorch shall not be used for sealing welding to avoid burning insulation. C. The three-phase copper barrier shall be connected with the ground wire respectively. The detailed barrier ground wire and steel armor ground wire shall be led out separately and insulated from each other. The position of the welding ground wire shall be as low as possible. 7、 Fundamental requirements for cable terminal and center discussion: A. excellent conductor connection; b. The insulation is reliable. It is recommended to adopt radiation crosslinked heat shrinkable silicone rubber insulation material; c. Excellent sealing; d. Sufficient machine strength can comply with various operation conditions. 8、 The cable end must be waterproof and corroded by other corrosive materials to prevent breakdown caused by aging of insulation layer caused by water tree. 9、 Crane or forklift must be used for cable loading and unloading to prevent horizontal transportation and placement. Cable car must be used for large cable placement to avoid external force damage to the cable or scratch the insulation layer due to manual drag. 10、 If the cable cannot be laid in real time for some reason, it shall be stored in a dry place to prevent sunlight exposure, water inflow at the cable end, etc. Secondly, it is also a link that can not be underestimated, that is, it is necessary to conduct acceptance inspection on the installed cables to see if there are omissions. 1、 First, the user shall check and accept the cable to see if it is damaged, and the construction personnel shall test the resistance and insulation resistance of each cable with a multimeter to confirm whether the cable resistance and insulation are normal, and record it. 2、 The supervision personnel of the user are invited to accept the whole laying. The main acceptance items are: a) whether the insulation layer is laid smoothly; B) If reflective film is installed, check whether the laying of reflective film is smooth; C) Whether the barbed wire mesh is installed smoothly and fixed. D) After the heating cable is energized, check whether the surface temperature of the cable has increased significantly, and sign on the acceptance sheet for confirmation.
Instructions for Use of Cable Fault Tester
Instructions for Use of Cable Fault Tester
When using the cable fault tester, we should first look at some simple waveform diagrams to analyze different cable faults, and then find out the fault points through the corresponding methods. The following is our simple analysis and description. 1. Test the low resistance grounding, short circuit and open circuit faults of the cable with the low voltage pulse method. A. no other auxiliary equipment is needed at this time. A clip wire is directly connected to the input and output interface of the cable fault location host. Clamp the red clamp of the clamp wire on the faulty phase core wire of the faulty cable, and the Black clamp on the sheath ground wire of the cable. B. Start the power switch of the instrument, the screen saver picture will appear on the screen, and click to enter the interface automatically. At this time, the default state of the instrument is "low voltage pulse method". The use method shall be selected according to the type and length of the tested cable on site and the fault nature preliminarily judged. When it is set to "low voltage pulse method", wave velocity measurement can also be carried out on this interface, and historical files can be opened to view previous test results. C. After setting the equipment parameters, click the "sampling" button, and the instrument will automatically send out test pulses. This interface will display the (open circuit) full-length waveform of the cable (as shown in Figure 5) or the low resistance grounding (short circuit) fault waveform (as shown in Figure 6). If the waveform is not good, the operator shall adjust the "median" and "amplitude" and observe the collected echo until the operator thinks that the amplitude and position of the echo are suitable for analysis and positioning. Basic information such as instrument parameter setting is also displayed at the bottom of the screen. During operation, pay attention to the operation status at the bottom of the screen. D. Waveform positioning reading distance. It is easy to judge the distance of low-voltage pulse, as long as the cursor is positioned to the starting point of transmitted and reflected waves respectively. E. When "saving", the test results need to be retained or reserved for comparison. The "saving" function in the instrument should be used to save the measured waveform in the instrument database. If the tester thinks it is necessary to save the test results, he can click "save" and operate according to the prompt in the submenu. 2. The high resistance leakage fault (including high resistance flashover fault) of the cable is tested by the impact high voltage flashover method. The instrument can test the high resistance leakage fault of the cable by the impact high voltage flashover method. Impulse high voltage flashover method is a popular traditional detection method in China. Many users are used to this method. The external circuit is relatively simple, but the waveform analysis is more difficult. Only on the basis of a large number of tests and some experience can we master it skillfully, but it is still an effective test method. Connect the current sampler attached to the instrument with the host with the signal wire and place it next to the grounding wire between the cable and the high-voltage equipment. As long as the output voltage of the impulse high voltage generator is high enough, the fault point will be broken down under the impulse of this impulse high voltage, and the radio wave reflection will be generated in the cable. The current sampler transmits the induced reflected wave obtained from the current signal on the ground wire through magnetic coupling to the cable fault location host for a / D sampling and data processing, and displays the collected waveform on the screen for fault distance analysis. After the cable type and sampling frequency are determined, you can click the "sampling" button to wait for sampling. Once the high-voltage generator has impulse high-voltage flashover, the instrument will automatically carry out data acquisition and waveform display. The red waveform at the top of the screen is the waveform after local amplification, and the blue waveform at the bottom is the full picture of the test waveform. When the ideal waveform is collected, the "waveform scaling" and displacement and moving cursor can be operated to calibrate the fault distance. The operation method is consistent with the low-voltage pulse method. 3. Wave velocity measurement cables produced by different manufacturers, although the models are the same, the differences in process and medium formula will lead to the differences in radio wave propagation velocity. If the average wave propagation speed given by the instrument is directly used, it will cause a certain test error. In order to test the fault distance more accurately, it is often necessary to recheck (test) the radio wave propagation speed of the cable.
How to Use Network Cable Tester_ Application Method of Network Cable Tester
How to Use Network Cable Tester_ Application Method of Network Cable Tester
Now cables are used in all aspects of people's production and life, so mastering the operation method of network cable tester is the most basic requirement for cable users. So how to use network cable tester?Application method of computer network cable tester1. Insert the two ends of the network cable above the main and auxiliary survey lines respectively, and you can insert any head at will;2. Then turn on the switch of the line measuring instrument;3. Observe whether the indicator lights of 1-8 on the main and auxiliary line measuring instruments are on, and the order of lights is correct.4. For example, 1 light on the main survey line instrument should be on, and 1 light on the auxiliary survey line instrument should also be on. If the 1 light on the main line measuring instrument is on and the 2 light on the auxiliary line measuring instrument is on, it indicates that there is a problem with the network cable and it can not be used normally;5. Among the eight lights, as long as the lights 1, 2, 3 and 6 are on, the network cable can be used, because the data is transmitted through these four lines, and the other four lines are not used to transmit data.There are two standards for the order of network cables:1: The standard of t568-b is orange white, orange, green white, blue, blue white, green, brown white and brown.2: The standard of t568-a is green white, green, orange white, blue, blue white, orange, brown white and brown.The first standard is generally used.Second, insert the crystal heads at both ends of the network cable into the RJ45 port of the main tester and the remote test end respectively, and turn the switch to "on" (s is slow gear). At this time, the indicator heads of the main tester and the remote test end should flash one by one.Test of direct connection: when testing the direct connection, the indicator lights of the main tester should flash one by one from 1 to 8, and the indicator lights of the remote test end should also flash one by one from 1 to 8. If this is the case, it means that the connectivity of the through line is OK, otherwise it has to be redone.Test of interleaved lines: when testing interleaved lines, the indicator lights of the main tester should also flash one by one from 1 to 8, while the indicator lights at the remote test end should flash one by one in the order of 3, 6, 1, 4, 5, 2, 7 and 8. If so, the connectivity of interleaved lines is OK, otherwise it will have to be redone.If the line sequence at both ends of the network cable is incorrect, the indicator lights of the main tester still flash one by one from 1 to 8, but the indicator lights of the remote test end will flash one by one according to the order of the line numbers connected with the main test end. In other words, the remote test end cannot flash in the order of the above steps.Phenomenon of wire open circuit testWhen one to six wires are open circuit, the indicator lights of the corresponding wire number of the main tester and the remote test end are not on, and other lights can still flash one by one.When 7 or 8 wires are open circuit, the indicator lights at the main tester and remote test end are not on.Phenomenon of wire short circuit testWhen two wires are short circuited, the indicator lights of the main tester will still flash one by one in the order from 1 to 8, while the indicator lights corresponding to the two short circuits at the remote test end will be lit at the same time, and other indicator lights will still flash one by one in the normal order.When three or more wires are short circuited, the indicator lights of the main tester still flash one by one from 1 to 8, while the indicator lights corresponding to all short circuits at the remote test end are not on.

A Guide to Cleaning High Voltage Detector Tester - Do-it-yourself
A Guide to Cleaning High Voltage Detector Tester - Do-it-yourself
A non-contact voltage tester is a safe method to ensure that no current touches the wire. It is lightweight, makes no noise and has a hot wire covered with plastic insulation.If you hear continuous chirping or see a series of flashes, this confirms that the tester has detected voltage. A voltage tester is a simple device that checks whether electric current is flowing through a circuit.A voltage tester is helpful when performing electrical work such as wiring, installing lights or troubleshooting household appliances, as it can warn you of unsafe situations by detecting currents that you might find the hard way. You can also use voltage testers to check that wires have enough voltage to power certain electrical devices or machines. The simplest type is the neon-colored two-wire tester, which measures from zero to 500 volts.If the voltage exceeds 9.6 volts, this means that the battery has become sulphate and can no longer absorb any charge. High voltage detectors that detect AC and DC voltages have a longer service life and the tungsten carbide tip is protected by a plastic cap when not used.If you wish, you can take the test a little further and deactivate the ignition injection in order not to start the engine. This will allow you to crank up the engine, but we suggest that it lasts no longer than 1.5 seconds.When the battery is fully charged, the voltmeter should indicate that it maintains a voltage of 9.6 volts or higher. If your voltmeter shows a voltage between 12.4 and 12.8, this means that your battery is in good condition.A voltage of 12.9 volts is a good indicator that your battery has an excessive voltage. If you have a voltmeter with a voltage of 12.2 volts, you should consider dripping a charge into your battery. In this case, switching on a high beam deprives the surface charge of excessive voltage.The CAT voltage specified on the tester or accessory must match the electrical environment in which you are using it. Be sure to test the absence of voltage before performing any tests that are necessary for PSA. If the absence of the voltage test proves that the circuit is dead, it should be considered as activated.In older homes, do not assume that a wire box is a dead circuit breaker. Your digital multimeter should last long before it breaks or wears out. Testing a lead temperature sensor with a fuse, for example, does not work.The conductor of the circuit board wired into the device must be checked to ensure that the device is on. Place a tip of the probe at the end of the conductor, where the fuse must be checked. If one of the components of a circuit board is switched off, the device should switch off the current by separating one end of each component from its circuit.Some products have remote displays or wireless contactless tools that help you get out of danger by allowing measurements to be made without the activated part making contact. The live-to-dead or live test method requires you to test the functionality of your devices without knowing the voltage source before making measurements. Use this method to ensure that your instrument is working properly before you take any measurements.If you would like to repair cars or electronics and electrical appliances, a multimeter is a handy accessory for your DIY kit. If you do not have it, you can use a voltage detector (instead of a voltmeter) or a continuity tester (instead of an ohmmeter). When used correctly, the multimeter indicates whether the white or black wires in the reverse socket are grounded when the cable enters the box that feeds the socket.Working with the main power supply can be dangerous and you may suffer shock and electrocution if you do not take appropriate precautions. Read and understand your multimeter's manual and the warnings it contains before using it to measure main current and voltage.If you are experiencing faulty wiring or any type of damage, repairs or alterations should be performed by a qualified electrician after further testing or conversion work has been carried out.Once the conversion work is complete and the power supply is restored, perform a few basic tests to make sure the switches and sockets work. If you test a wall socket powered by a wall switch known as a switch socket (a common means for powering a floor lamp, for example), you can use a non-contact voltage detector to check the wall socket is in the position of the wall switch. Use a socket tester on the outlet to search for switches and a non-contact voltage tester to place any kind of electrical load on the circuit.You can add the creation of it to a beautiful piece of it: you can wear it by using a lock, uni-T voltage detector, pen detector, sound light, alarm LED flashlight, cute little pony cupcake packaging that makes children giggle, layer of chevron counting from the innermost layer to the perforation in the outermost layer, bachelor train, 125 specialty, beautiful silverwork, 5 citrus stones in addition to rainbow-pleasing shades.
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.

The Evolution of the Handheld Laser Measuring Device in China
The Evolution of the Handheld Laser Measuring Device in China
The Great Wall of China, the Taj Mahal, the Roman Colosseum and the pyramids are just some of the largest and small gauges in the world in critical buildings. The development and mastery of these tools has been crucial to the evolution of the human species. Laser pointers are also used in robotics, for example, laser guidance guides a robot into a target position using a laser beam. Green laser pointers are used for similar purposes in daylight and over long distances. Another common use of lasers in entertainment is the special effects used in laser shows. Clubs, parties and outdoor concerts often use high-power lasers as security for the spectacle. For example, construction companies use high-quality laser pointers to increase the accuracy of displaying certain distances when working on large-scale projects. In astronomy, laser pointers can be mounted on a telescope to align the telescope at certain star locations. Green laser pointers are also used by astronomers for star parties or lectures on astronomy. Laser rangefinders have built-in processing capabilities that allow them to triangulate, calculate and measure distances, as well as calculate area and volume. They are accurate enough to measure long distances and display fast measurement results, compared to traditional bands used for measurement applications. With the various functions that digital handheld meters offer, the demand for these devices via tape increases. A major factor in the growth of hand-held laser rangefinders is the growing construction sector. Noyafa is committed to scientific and technological applications of laser detection. The growing demand for digital measuring instruments for precise measurements and the resulting growing demand for hand lasers and distance meters in the construction industry is a key factor in the growth of the market for hand lasers and distance meters worldwide. Measuring tools continue to evolve with technological advances such as lasers. With the development of mass production of integrated circuits (IC), the measuring tapes have become digital. This is different from 100-foot measuring tapes, which are made of fabric and used to mark the exterior dimensions of large buildings.
Voltage Detector Pen: a History of Voltage Detector Pen
Voltage Detector Pen: a History of Voltage Detector Pen
The tester is designed to detect the main voltage and does not provide any indication of low voltage control circuits as used in doorbells and HVAC controls. A voltage detector is used to detect sockets, power supplies and insulated wiring. Unlike a tonne or an ammeter, which detects changes in a magnetic field, a detector uses the current flowing through the wire in question as it detects alternating electric fields emitted by the AC conductors.In order to reduce the potential for false alarms on low voltage devices, I recommend inspectors to use a voltage tester starting at 90 volts. I don't buy voltage sniffers that run on button batteries because they're hard to find.It costs a little more than most other voltage sniffers, but it's worth the price. I've had it for three years and it's the most reliable and robust non-contact electrical tester I've ever owned. The non-contact voltage tester is a great voltage tester that can be called Fluke, and is characterized by a compact design that is easy to use.A good voltage tester should be small enough to carry and provide an accurate measurement that tells the user whether voltage is present or not. Each time you use the tester, voltage sniffer manufacturers recommend testing with a known power source to ensure proper function.To use a non-contact voltage tester, touch the tip of the tester with the wire you test with the socket and the tip must be placed with a small slot on the front panel. Manufacturers of voltage sniffers also recommend holding a tester with bare hands and keeping it close to the body. Fluke 1AC-II Non-Contact Voltage Test Tip: A bright red beep that sounds when voltage is detected.The invention of the non-contact voltage tester described above is a kind of voltage indicator that produces a signal of limited duration when the operator switches on to turn the tester on, which is operated by the user when no voltage at the probe tip is detected. The signal tells the operator that the battery is on, indicating that the device has a light or sound source at work. The use of voltage testers consists of touching one probe on a wire connection and the other probe on the opposite wire connection.Under certain circumstances, the voltage sniffer may not be able to detect the current if you do not hold it down, as shown in the following clip. In the United States, the Consumer Product Safety Commission states that the button can remain pressed during a power-to-power cycle, causing the tester to work incorrectly.Voltage is the potential difference between the two conductors and the ground. Measured as voltage in phase, a phase of zero volts indicates that the two energized conductors are in the same phase.The reading is the product of the current flowing through the circuit and is calibrated to read the voltage in kilovolts. The test lamp, the test light or the main test meter is an electronic tester used to determine the presence of electricity in the device under test. A test light is a simple but expensive measuring instrument, such as a multimeter, which is sufficient to check the presence of a voltage in a conductor.Choose a detector that displays the power level with an acoustic, visual or vibrating signal. Find a variety of Grainger voltage detectors to test battery and circuit integrity.CAP-40 houses the battery [41], which supplies the voltage detector circuit with energy (Fig. The additional energy from the lamp and the power amplifier is supplied by a small internal battery that does not flow through the user's body.The socket tester is about the size of an electrical plug and works by plugging it into the socket. They have grooves that hook into the surrounding wires and detect the voltage of the lead wire at the point where the tester checks the contact with the socket. The tester can test voltage and polarity and check the outlet wire, but it is not able to test the circuit directly at the outlet itself.Techineer is not responsible for any import duties or taxes, including VAT, that occur when a shipment reaches your destination country, and these are only your responsibility as a customer.We approach each case on a case-by-case basis and try our best to find a satisfactory solution. After talking to a 20-year veteran electrician and testing seven leading models for eight months we found that the Klein NCVT-3 was the best model.
