Working Principle of Cable Fault Tester
Working Principle of Cable Fault Tester
Working principle of power cable fault tester consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, a pathfinder shall be used to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. The working principle of the application of arc reflection method (secondary pulse method) in cable fault location: firstly, a high voltage pulse with a certain voltage level and energy is applied to the faulty cable at the test end of the cable to make the high resistance fault point of the cable break down and burn arc. At the same time, add the low-voltage pulse for measurement at the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and reflects on the surface of the arc. When arcing, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will change obviously in impedance characteristics, so that the waveform of flashover measurement becomes a low-voltage pulse short-circuit waveform, making the waveform discrimination particularly simple and clear. This is what we call the "secondary pulse method". The received low-voltage pulse reflection waveform is equivalent to the waveform of a wire core completely short circuited to ground. Superimpose the low-voltage pulse waveform obtained when releasing the high-voltage pulse and when not releasing the high-voltage pulse. The two waveforms will have a divergence point, which is the reflected waveform point of the fault point. This method combines low-voltage pulse method with high-voltage flashover technology, which makes it easier for testers to judge the location of fault point. Compared with the traditional test methods, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into the simplest low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. The triple pulse method adopts the double impact method to prolong the arc burning time and stabilize the arc, which can easily locate the high resistance fault and flashover fault. The triple pulse method has advanced technology, simple operation, clear waveform and fast and accurate positioning. At present, it has become the mainstream positioning method of high resistance fault and flashover fault. The third pulse method is an upgrade of the second pulse method. The method is to first measure the reflected waveform of the low-voltage pulse without breaking through the fault point of the measured cable, then impact the fault point of the cable with the high-voltage pulse to generate an arc, trigger the medium voltage pulse when the arc voltage drops to a certain value to stabilize and prolong the arc time, and then send the low-voltage pulse, Thus, the reflected waveform of the fault point is obtained. After the superposition of the two waveforms, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stabilize and prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse method. Compared with the secondary pulse method, the triple pulse method does not need to select the synchronization time of arc burning, and the operation is also more simple.
Fiber Optical Tester - How to Use the Best One for Your Needs
Fiber Optical Tester - How to Use the Best One for Your Needs
Small portable microscopes were once developed to test fiber optic cables. One of the best applications of such a device was the identification of trace fibres to determine the correct connection. This made it possible to find a specific fiber in a multifiber cable for proper connection and installation.Fiber optic is a fantastic medium for spreading light signals, but it needs to be amplified in contrast to copper cables. High-quality singlemode fibers have attenuation and a power loss of only 0.1 dB per kilometer. The signal power (measured in dB) is higher at the head of the network connection than at the end of the customer connection, and it is impossible to suffer light degradation over the length of the connection.When testing fiber optic cables for optical losses, the fiber tester must be connected to a test source that provides optical light on a standard launch cable calibrated to a 0 dB loss reference. For example, when the light source operates at a wavelength of 1310 nm, the optical power meter for testing should be set to 1310.A power meter at the other end of the circuit measures the test source for each fiber tested and quantifies the loss (dB) of each fiber during the test. For double-end loss tests, attach the cable to be tested to two reference cables connected to the source, one per meter. This allows you to measure the two connectors lost at one end for each power cable in the cable.If your electricity meter has an internal memory for data recording, make sure you know how to use it. Use your equipment in the office to test one of your reference tests (bridging cables in each direction) and use the end loss test to make sure it is good.Connect the optical source to Jumper 1, testing one end of the system fiber. Apply the adapter and insert the second jumper for the test, Jumper 2, which contains the same size fiber as the first, and an optical power meter. For the receiver, a separation cable is attached to the receiver socket to measure the performance of the meter.The power of the fiber optic cable or optical return loss is the light pulse that enters the end of the fiber optic core and the percentage of light reflecting back to the source. Optical fiber loss varies according to wavelength, so the optical power meter uses the same wavelength as the light source. The optical performance at the end of the fiber is the basis for the loss measurement, and the power source is presented to the receiver.Both singlemode and multimode fibers (VCSEL) are sensitive to optical return losses (ORL) expressed in decibels (dB). It affects the fiber and laser light source and reduces the data transmission speed.The OTDR test measures the backscattering of light to assess the quality of fiber optic cables. If the light at the other end is not visible, fractures or other problems may occur along the length of the fibre strand.The best way to test such impurities is to use a fiber optic or fiber optic microscope, a special microscope developed for inspection of fiber optics. Fiber optic communication systems operate in the electromagnetic spectrum in the infrared range which is invisible to the human eye.Fiber optic cables have become a more popular choice than Ethernet for network and telecommunications applications due to their high data transmission speeds over long distances. Fiber is the dominant medium for all types of mission-critical data center connections, backbone buildings, and remote campus networks. As the popularity of bandwidth-intensive applications increases, demand for fiber-optic installations and infrastructure is accelerating.Fibre optic cables play an essential role in the telecommunications industry. Testing fibre optic cables is considered one of the most confusing and misunderstood stages of installing a fibre optic system, but it is one of the last and most important procedures for installing a fibre optic network. For optimal savings in system performance, it is important to select a fiber optic cable that is matched to a spectroscopic analysis system.AFL Optical Fiber Identifier (OFIS) is a robust, easy-to-use test instrument that detects the presence of signals in optical fibers. The OFI is an important tool for field technicians to ensure live fibres are not separated and provides the ability to track the fiber from end to end.The optical time domain reflection (OTDR) is used as a fiber optic cable tester to test optical loss. The fiber optic cable is guided to one end through an OTDR to analyze the backscattering of light returning to the source using a high-power laser light that emits a predetermined pulse interval and is connected to the cable. This is the one-sided fiber test method used by fiber optic testers to analyze losses and pinpoint their location for installation, maintenance and troubleshooting.Fiber optic testing requires special tools and instruments to select the appropriate components and cables for the equipment to be tested. The most important test of insertion loss in an installed fiber optic cable system is carried out with a light source power meter (LSPM) and an optical loss tester (OLT), which is required by international standards to ensure that the cable is not lossless within the acceptance and installation budget.If it is a long installation cable with intermediate connections, you should verify each individual connection with an OTDR, as this is the only way to ensure which is the best. For this purpose, the loss testing method specified in OFSTP 1.4 is tested for losses in the installed cable system. Power Meter Optical Loss Test Set (OLT) Test Kit With the right equipment and adapter, the cable system you are testing (e.g.

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.
Basic Functions of Cable Fault Locator
Basic Functions of Cable Fault Locator
The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable. Dear customers: the company also has products such as underground cable fault tester, cable identifier and cable tie tester. You can call the company's service phone through the web page to learn more product details. Perfect and beautiful service is our pursuit. New and old customers are welcome to buy their favorite products at ease. We will serve you wholeheartedly!
