What Is the Difference Between Medium and Low Voltage Cable Fault Tester and Traditional Tester
What Is the Difference Between Medium and Low Voltage Cable Fault Tester and Traditional Tester
Since the buried cable appeared in our life, cable fault detection has become a test of people's work. How to accurately find out the cable fault point through layers of soil requires not only the experience of maintenance personnel, but also corresponding equipment support. Cable fault tester is one of the commonly used detection equipment. Today, we mainly discuss the difference between the medium and low voltage cable fault tester and the traditional one. Difference analysis between medium and low voltage cable fault tester and traditional cable fault tester: first, introduction of fixed-point method of cable fault. There are two kinds of cable fault rough measurement methods: electric bridge method and pulse reflection method. There are the following methods for cable fault fixed point: 1. Acoustic measurement method: acoustic measurement method is used for fixed point, which is a common method for cable fault fixed point from the past to the present. And it is the most effective method. However, the instrument used has developed from a simple acoustic electric amplifier to an acoustic magnetic synchronous fixed-point instrument widely used now. The fixed point of acoustic measurement method is applicable to high-voltage cable, low-voltage cable, directly buried cable, cable trench cable, etc. 2. Step voltage method: step voltage method is adopted for fixed point, which is mainly aimed at the fixed point of outer sheath grounding fault with requirements for cable outer sheath insulation. Now, step voltage method can also be used for fixed point of grounding fault of some directly buried unarmored low-voltage cables and wires. 3. Electromagnetic method and audio method: it is feasible to fix the point with electromagnetic wave or audio method in principle. However, from the current situation, there is no fixed-point instrument with reliable performance and practical application. In other words, the fixed-point instrument using electromagnetic wave fixed-point is still being developed by various scientific research institutions, which needs to be further verified and improved in practice to reach the practical application level. 2、 Introduction to medium and low voltage cable detector (bridge tester): most of the medium and low voltage cable detectors in circulation in the market now complete the function of cable fault rough measurement. Its principle is generally using the electric bridge method, but now it has adopted computer technology and intelligent electric bridge. There are low-voltage bridge, high-voltage bridge and so on. Some instruments also use the principle of ultra-high voltage digital bridge. The voltage applied to the fault point is generally more than 200V, and the most Gao can be added to 20kV. For cable fault with low fault resistance (resistance less than 600m & omega;). The fault distance can be roughly measured with medium and low voltage cable detector. Scope of application: applicable to leakage fault test with low fault resistance value. It is generally used for cable fault test below 6000V & lt; Rough measurement of fault distance & gt Advantages: for cable faults suitable for testing, it is simple to use and has low technical requirements for users. Fool test. In addition, for some fault points, such as some cable joint faults, due to the long creepage distance of the fault point, the fault of flashover discharge cannot be formed. Because the pulse flash method cannot be used to roughly measure the fault distance, the electric bridge method has its advantages. In the actual test, when the insulation resistance of the fault point is lower than 100m, but the high-voltage flashover test (impulse voltage is greater than 20kV), the low-voltage measured discharge current displayed by the operation box does not exceed 5a, and the sound is clear when the ball gap is discharged, which indicates that the fault point has not formed flashover discharge, and the flash tester displays the full-length waveform of the cable. In this case, we can basically conclude that the cable intermediate joint is faulty. The middle head can be excavated directly, and the cable fault pointing instrument can be used for accurate pointing, so as to further diagnose the fault point.

How to Make a Handmade Vfl Fiber Tester
How to Make a Handmade Vfl Fiber Tester
Inspection with a red light source in a fibre optic network requires a number of connection / separation operations. Optical troubleshooting devices illuminate fibers that are defective or damaged connectors, patched cords, defective splices, splice trays that are too narrow, or fibers that are bent into gear trays. The choice between perm output mode for continuous error illumination or flash output mode facilitates fault locating. Visual Troubleshooting Devices (VFL) are an important tool for locating defective or in some cases excessive bending in fiber optic cables. A visual fault locator produces high-intensity red laser light when a fiber optic ends in a factory-polished fiber optic connector. VFLs are optimized for use with singlemode fibers called OS1 and OS2, but can also be used with the multimode fiber families OM1, OM2, OM3, OM4 and OM5. The VFL is also used as a tester to check fiber-to-cable continuity by tracing the fiber-to-fiber for faults such as brakes, faulty splices, sharp vessels, etc. In the fiber-to-fiber cable. A visual error locator, also known as visual error detection, is used to locate errors. And of course the technician must be able to see the cable to locate a fault. It is a cost-effective method to detect defects in the fiber optic, such as sharp curves, broken or faulty connectors, and other defects that transmit red or green light. A visual fault locator (VFL) is a basic fiber optic troubleshooting for fiber connections. It is also known as Visible Laser, Fiber Fault Detection, Fiber Fault Detection, or Visual Fault Detection and is available as a red laser or light design that injects visible light energy into the optical fiber. The optical time domain reflectionometer (OTDR) is used as a fiber optic cable tester to test optical losses. Using a high-intensity laser light that emits predefined pulse intervals and is connected to the cable at one end, the cable is guided through an OTDR to analyze the backscattering of the light and return to the source location. It locates errors in the OTDR (dead zones) and allows the identification of fibers from one end to the other. The One-End Fiber Test is a method used by fiber optic testers to analyze a loss and determine its location for installation, maintenance and troubleshooting. The Hobbes Fiber Checker Pro and Visual Fault Locator (VFL) can be used to inspect and detect fiber optic cable defects. With VisifaultTM and VFL you can diagnose and repair simple fiber connection problems and flukes in the network. Whether it's installing new fibers or troubleshooting an existing network, the Visual Fault Identifier is a useful and convenient kit. You can diagnose fiber-optic connection problems with fiber-optic cables or fiber-optic pigtails using a visual troubleshooting device. Some fiber optic troubleshooting devices are equipped with adapters that are not compatible with your connector type, so use an additional adapter if necessary. VFI and VFL are ideal tools for locating the large number of problems that can occur at connection points and fiber optic cabinets hidden from OTDRs, blind spots and dead zones. Sharp curves, breakages, faulty connectors and other faults such as leaks and lamps allow technicians to quickly detect defects. Colors can be difficult with red laser light, but optical error localizations such as brown, black and green (e.g. The signal transmitted in fiber optic cables is between 1,300 and 1,650 nm wavelength, which is invisible to the naked eye. Lower wavelengths such as 630 nm and 635 nm are bright enough to locate disturbances easily, but cannot travel much higher than 670 nm wavelength. Several manufacturers choose wavelengths below 650 nm for their optical fault spot specification, which can cover a distance of 5-8 km from the center of a singlemode fiber with minimal attenuation. The Noyafa Power meter uses absolute and relative power measurements at 50 and 26dBm at 850, 980, 1300, 1310, 1490, 1550, 1625 and 1650nm wavelengths. The Fiber Checker Pro is a pen-like design case that makes it a portable and practical tool for checking fiber optic cables. Rhodium Plated 925 Silver 1 Nut Pendant 2.4 Necklace Leader Metal Impeller Integration for Superior Durability. The vinyl we use is designed for outdoor vinyl for 10 years, 3 AA batteries are required (not included). Easy to assign and show a new look, contact us for return / exchange permission within three days of delivery date and mark me on your photo with sugar. Filled non-commercial plaster on glass tube, topped with a layer of natural sand and hooded raincoat to facilitate any outdoor activity. The same attention to cleanliness applies to reference cables and test equipment connections. When using a VFL as an optical fault location fiber tester, fault location and eye safety are important. The VFL uses a high intensity laser light source and its fiber core is illuminated so that it can be viewed with the naked eye.
How to Diagnose and Solve Cable Leakage with Cable Fault Tester
How to Diagnose and Solve Cable Leakage with Cable Fault Tester
How can the cable fault tester diagnose and solve the cable leakage? As the main cable fault, when the power cable leaks to the earth, it will produce a strong to weak directed electric field gradient around the fault point on the ground. The amplitude and direction of the signal can be measured by Bao Shun Tong cable fault measuring equipment along the cable path. Before and after the fault point, the direction pointed by the galvanometer pointer is opposite, so as to find the fault point of the cable and achieve the purpose of accurate positioning. 1. Cable fault diagnosis depends on the nature of the fault. Cable fault can be divided into low resistance grounding or short circuit fault, high resistance grounding or short circuit fault, wire break fault, wire break and grounding fault and flashover fault. Cable fault diagnosis can determine the type and severity of cable fault, and it is also convenient for testers to test it with different test methods according to different fault types. For example, for high resistance faults, the impulse flash method can be used to locate the fault location. 2. Cable fault location. Cable fault location is also called rough measurement. There are two rough measurement and location methods: electric bridge method and wave reflection method. At present, wave reflection locator is more popular. However, several cable faults are difficult to find by wave reflection method, such as insulation defect points of high-voltage cable sheath, steel tape armored low-pressure cable, PVC cable and short cable can not be located. In addition, some high breakdown points cannot be broken down under impulse voltage and are difficult to locate. 3. Cable fault point. It is also called precise measurement. The cable fault can be accurately fixed through the methods of acoustics, electromagnetism, electronic signal processing and electronic cancellation theory. The LCD can display the sound pulse, magnetic pulse and the distance between the fault point and the probe test point at the same time. At present, the cable fault can be accurately fixed by the following four methods: (1) Acoustic measurement method: the high-voltage pulse generator discharges the fault cable, the fault point generates an arc and generates a discharge sound. When the cable is directly buried, it generates a seismic wave. The acoustic probe of the pointing instrument picks up the seismic wave signal and amplifies it and outputs it through the headset or meter head. (2) Step voltage method: it is mainly aimed at the fixed point of outer sheath grounding fault with requirements for cable outer sheath insulation. Now, step voltage method can also be used for the fixed point of some directly buried unarmored low-voltage cables and wire core grounding fault. (3) Electromagnetic method and audio method: fix the point with electromagnetic wave or audio method, that is, determine the fault point by using the change of electromagnetic wave signal or audio signal at the front and rear points of cable fault. (4) Acoustic magnetic synchronization method of cable fault tester: it is the comprehensive application of acoustic measurement method and electromagnetic wave method. Then, according to the above operation methods, we believe that the fault point can be found soon, and we can quickly repair and restore the normal operation of 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.
