Correct Use of Live Cable Identifier
Correct Use of Live Cable Identifier
The cable identifier has the main function of identifying a cable from a bundle of cables. The utility model is composed of a receiver and a connector of a signal generator and a sensor. It is commonly used in cable erection, migration, maintenance and fault handling. It is divided into live cable identifier and non live cable identifier. Let's talk about their own search methods. 1. Search method of live cable recognizer: when the line is live, we can't affect the normal operation. When identifying the cable with points, we use the induction method to measure. The high-frequency signal is transmitted through the caliper. After receiving the signal characteristics, the receiver filters through software and hardware. During phase identification, when the receiving caliper clamps the cable according to the current direction, the identified cable ammeter deviates to the right, Accompanied by audible and visual indication. The current direction of other cables is opposite to that of the identified cable, and the ammeter pointer deviates to the left. No audible and visual indication. This reflects the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. Since the signal current strength on the identified cable is the same throughout the line, the electromagnetic signal strength received by the receiving caliper along the cable is the same. In principle, the identified cable is not limited by the length of the identified cable. 2. Search method of dead cable identifier: the search method of dead cable identifier is basically connected with live identification. The generator feeds periodic unipolar voltage pulses into the cable to be identified. The cable needs to be grounded at the far end to ensure that enough current flows through the cable. The direction of pulse current fed into the cable can be used as an obvious identification standard, The outgoing current only passes through this cable. All other adjacent cables flow through the return current, but their polarity is opposite. The direction and size of the current flowing through the cable are detected through the receiver. It is equipped with an amplifier and connected in series in the circuit. The sensor clamps the measured cable. The magnetic field generated by the current flowing through the cable induces a voltage in the coil of the sensor, The voltage polarity is determined by the current direction and the direction of the sensor coil, so as to identify the cable. Since the cable shielding layer is usually connected to the ground, if other cables in the cable bundle are also connected to the public ground, the black output jack on the generator can be connected to the public ground. The return current is distributed in several cable shielding layers and divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear, The difference means that the output current and its divided return current are in the same channel.
Operating Steps of Live Cable Identifier
Operating Steps of Live Cable Identifier
1. Connect the transmitting source: the live cable identifier inserts the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamps the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. Both ends of the identified cable shall be reliably grounded. For cables that do not operate, the core wires at both ends can also be grounded. 2. Turn on the power switches of the transmitting source and receiver to check the direction: on the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At this time, the pointer of the receiver ammeter must deflect to the right, and there is an audible and visual prompt at the same time. If the arrow of the receiving caliper B points to the transmitting source end, there will be no audible and visual prompt, and the pointer of the current meter will deflect to the left. Remember the deflection direction of the receiving caliper gauge. 3. Identification: at the identification point, use the receiving caliper B to identify each cable. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time. On other cables, the pointer of the receiver current meter must deflect to the left without audible and visual alarm. The pointer of the current meter of the receiver deflects to the right, and the audible and visual alarm prompt is the cable to be searched and identified. This test result is unique. That is, no matter how many cables there are in the cable trench, when each cable is identified with the receiving caliper B, only the receiver current meter pointer on one cable (the cable to be found and identified) deflects to the right and gives an audible and visual alarm.

Intelligent cable fault tester is an important tool for maintaining various cables. It adopts a variety of fault detection methods, applies contemporary advanced electronic technology achievements and devices, adopts computer technology and special electronic technology, and combines the long-term successful experience in developing cable tester. It is a high-tech, intelligent and fully functional product. The intelligent cable fault tester is composed of three parts, which is used for the test of various faults of power cables, the search of cable path and cable burial depth, the daily maintenance and management of cable archives, as well as the fault test of railway and airport signal control cables and street lamp cables. Cable fault finding is generally divided into four steps: fault nature diagnosis, fault location, path detection and fault location. The methods of fault location mainly include: first, the bridge method, mainly including the traditional DC bridge method, voltage drop comparison method and DC resistance method; The second is the low-voltage pulse method, also known as the radar method, which is to input the low-voltage pulse signal into the cable through the instrument at one end of the cable. When the fault point with mismatched wave impedance is encountered, the pulse signal will be reflected and returned to the measuring instrument. This method has the advantages of simple operation and high test accuracy. It is mainly used to test line breaking and low resistance faults, but it can not test high resistance faults and flashover faults; The third is the pulse voltage method, which needs to apply DC high voltage signal to the faulty cable; Fourth, pulse current method, which needs to apply DC high voltage signal to the faulty cable; The fifth is the secondary pulse method.

Model Prototype: OXO Handheld Screwdriver
Model Prototype: OXO Handheld Screwdriver
This project focused on creating a low-fi 3D prototype of a potential design for a OXO electric handheld screwdriver with the following specifications:variable speed control you decide the mechanism/interaction and whether it is fluid or distinct settingsscrew-driver selection mechanism (either digital or non-digital your choice) allows you to automatically select and switch between either Phillips or flathead shape and five different sizes of each shape (for 10 total screwhead choices)screw-driver direction selection mechanism (non-digital) to either screw in or unscrewdigital readout (monochromatic, non-touch sensitive) of number of screws screwed and screws unscrewed for tracking your progress as a handypersoncan be used right or left-handedproduct dimensions are a minimum of 6 inches long and must be able to contain a rechargeable batteryproduct weight is between 11.5 poundsFor each of the feature criteria above, I came up with an idea for how I would implement it onto the prototype:Trigger pressure or wheel to control speedDouble wheel selection to change between head type and sizeA switch to control screw and unscrew optionsA digital number display to show the digital readoutA charging port and the end of the handleHere are my sketch ideas for how the features would look on the device:After sketching the prototype, I thought I had a pretty good idea of the layout of the controls but there were some things I realized as I was conceptualizing the design. There were a lot of features to implement onto the screwdriver that would be difficult to fit onto a handheld device so as I was sketching, I tried to consider space as a constraint. Another thing I noticed was that there was a big difference in readability between putting numbers side-by-side and one top of the other.PrototypeTo build my prototype I used cardboard and tape. I made the prototype larger than the actual size it would be so that I could clearly display the features and test the interface functionality with a user. Here is what the prototype looks like:AnalysisTo test this prototype, I sat down with a participant and asked them to screw in and unscrew a screw at a specified setting while vocalizing their thought process. The user was able to complete the task but there were a few features that were unclear.Features that were unclear to the user:Used the Phillips instead of a flat head on the screwThought the unscrew/screw switch was to activate the screw driverSuggested moving the placement of the controlsThings that went well:User was satisfied with the easy controlsWas easily held and comfortable in their handsAble to complete the task without major issuesThe prototype worked well to complete specified tasks but it was a challenge trying to fit all the features onto a small device. Another challenge was how to test a trigger that would rely on users pressure. Without outright telling the user how the device is reacting to their actions, it can be difficult to simulate. I would improve the layout of the controls by minimizing their size and moving the size selection to the handle. I would also use text instead of symbols to show the different screw head types because it seemed to confuse users during testing RELATED QUESTION What are POP materials when it comes to advertising?

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.
