A Guide to Cleaning Non Contact Voltage Tester - Do-it-yourself
A Guide to Cleaning Non Contact Voltage Tester - Do-it-yourself
The presence of alternating voltage can be detected by the tester by finding the current flowing through it. Take a voltmeter - a voltmeter that measures the difference in electrical potential between two nodes in a circuit.There are digital voltmeters that allow you to display the dial digitally. On a large scale, the voltage adjustment is called V. V measures the AC voltage, while V measures the DC voltage.It costs a little more than most other voltage sniffers, but it's worth the price. 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 did not buy a voltage sniffer that runs on button batteries, as they are hard to find.A non-contact voltage tester is a safe method to ensure that the current touches the wire. You do this by testing one of the wire connections and then a second probe on the other connection to find the voltage. You hear continuous chirping and see a series of flashes confirming that the tester has detected voltage.The non-contact tester lights up and beeps in combination when it comes into contact with a power cable or socket. Other hot wires are the wires that lead to other electrical appliances in the house that happen to cross the path of the switch. You can place the dead wire between the live wire and the dead wires by setting up a voltage sniffer on the electric field between the dead and the living wires.A voltage tester is a device that detects or indicates the presence of voltage on power cables, power cables, lights, circuit breakers, wires, sockets, etc. Non-contact voltage detectors are, as the name suggests, voltage detectors that do not have to come into contact with cables, cables or sockets. This works with AC mains supplies, junction boxes and when installing a new device, you can, for example, switch off the mains supply and check the voltage on the control panel.For non-contact voltage testers testing with a spring-frequency voltage sensor or voltage tester known to them, the safest way to ensure electrical conductors do not have voltage is to touch conductors before they are electrocuted.Non-contact voltage testers, also known as inductance testers, allow you to check the voltage of a wire or device without touching the wire or part. They are the safest testers and also the easiest to use.Manufacturers of voltage sniffers recommend holding the tester with bare hands and keeping it close to the body. They also recommend testing with a known power source to verify correct functionality each time you use the testers. A voltage tester is a socket analyzer that can be used on cables, wires, circuit breakers, lights, sockets, switches, etc.It is also a good practice to touch the wire bare end with an insulated tool, not a finger. As an additional precaution, if you do not work with the certainty that it will not cause any damage, turn the nut around the end. In this way, you are protected by switching off the current if the tester makes an incorrect measurement.If you work with a luminaire that has two switches, such as a three-way test, you have a switch in the upward position. Be sure to follow the instructions for the maximum amount of current that the meter can handle. As soon as you receive a reading from your meter, check if it has a switch called DC.Routine tasks such as changing sockets and lights are manageable and safe as long as you respect the current rights of the tool. Get used to taking the time and effort to provide yourself with double or triple protection. If you fill in a CAPTCHA to prove that you are a human being, you get temporary access to web properties.The best way to pay for electricity in your own home and protect yourself from zapping is to use a combination of non-contact circuit tester and working switch socket light. Touch-free testing equipment is the best tool for double-checking performance when working with sockets, switches, boxes and related devices. It is easy to find tools in retail stores, socket voltage testers and continuity testers are the most popular among mechanics, and most consider the latter to be the most reliable.We talked to a 20-year-old electrician who spent eight months testing seven LED models and found the Klein NCVT-3 is the best. The top three recommendations for the best value are Sperry STK001 non-contact voltage tester and Outlet Tester Kit, two tools that offer a variety of voltage detection applications and many features and offer the best value in their price range.

How to Ensure the Correctness of Cable Identification by Live Cable Identification Instrument
How to Ensure the Correctness of Cable Identification by Live Cable Identification Instrument
In the 21st century, with the rapid development of railway, the speed per hour is faster and faster, and the marshalling operation is more and more intensive, it is necessary to ensure the normal operation of electrical service system. How to ensure the correctness of cable identification by live cable identification instrument, we will discuss and explain this problem below. In the electrical service support, the fault and construction of signal cable shall be tested and identified quickly. If the identification is wrong, it will have a very serious impact and cause train accidents. So let's talk about the identification of electrical service system. 1、 Current situation and disadvantages of signal cable identification in telecommunication system target cable identification is required in field work such as emergency repair, relocation and replacement of signal cable. Since there is no suitable instrument, most of our signal cable maintainers use the following methods to identify. First, wait for the skylight point, and remove the signal cable sheath when the skylight point; Secondly, two core wires are selected as the identification wire, and the two core wires are also found at the end; Finally, use the blade to cut the skin of the selected two core wires for short connection, and use the external meter to measure whether the selected two core wires are short circuited at the end. If they are short circuited, it means that the identification is accurate, otherwise, the identification is wrong. However, there are many disadvantages in using this method for identification: 1. Generally, such work is rush repair, which must be completed in the skylight point. If it takes up the time in the skylight point for identification, the rush repair time will be greatly reduced, and some even need to apply for two skylight points to complete a work; 2. After the selected two core wires are short circuited, the two core wires found at the end may not correspond, resulting in wrong results; 3. The outer skin and copper shield of the cable shall be broken. After identification, this place shall be restored. In the future, this place is a joint and a potential fault point. 4. The most important thing is that this identification often produces wrong results, resulting in operation accidents. 2、 Current status of cable recognizer 1. Current status of identification equipment (identification and attached identification): status of identification 1: conventional cable recognizer is designed for power cable identification and is widely used in the power field. Whether imported or domestic, it has two service conditions: 1) it has high requirements for the loop resistance of the target cable, Generally, it shall not exceed 50 ohms. If it exceeds the range of this circuit resistance, the equipment will not work normally, which is beyond the range of equipment use; 2) Disconnect at least one end of the outer armor grounding (same as shielding grounding) at both ends of the target cable, so that the applied signal cannot return from the target cable. Therefore, this power cable identification instrument is not suitable for the identification of electrical signal cables. Identification status II. When promoting digital path tester, some manufacturers publicize that the equipment has identification function. In fact, when using the digital path tester to identify, if the receiver touches the identified cable, which signal is the strongest, that is the identified cable. This recognition method has a single judgment basis in recognition, only the signal size, no signal direction, and can not be used as the final judgment. Moreover, such equipment has great attenuation on the signal cable, and the identification of long-distance signal cable can not be done at all. 2. Conclusion: the use conditions of power cable identification instrument and digital path tester determine that these two types of equipment are not applicable to the signal cable of electrical service system. 1) For the signal cable of electric service. The cable is very long, with a length of more than 5km, and some can reach more than 20km; The wire core is very thin, generally 1mm ² , The resistance is 23.5 Ω per kilometer, and the cable body resistance of more than two kilometers has reached the critical value of equipment test, so the loop resistance problem has become a hard wound of the conventional identification instrument. 2) In the electrical service system, it is very inconvenient to open the outer armor grounding (the same as shielding grounding) of the signal cable. The regulations of each Railway Bureau and railway line are inconsistent. Some cannot be opened, some must be opened in the skylight point, and must be restored before the end of the skylight point. Based on the above two points, the conventional cable identifier and Pathfinder can not meet the requirements of signal cable identification of railway electrical service system. 3、 During the test of railway signaling cable identifier, the requirements for loop resistance can reach 1000 Ω, and there is no requirement for armored grounding or ungrounded of the target cable. The utility model solves the difficult problem of identifying the signaling cable. The railway communication cable is specially designed and can be used online. It has the characteristics of micro power transmitting signal, has no crosstalk and interference to the data transmission of adjacent cables, and accurately finds out the required cable. The size double jaw configuration can not only identify the cable, but also identify the wire pair in the cable. Color large screen LCD, live voice prompt, friendly intelligent man-machine interface, and its unique intelligent orientation can indicate the signal direction, which makes the operation simple and practical. It is especially suitable for field use. Even untrained personnel can use it quickly. Through live measurement, it is not necessary to apply for night skylight time to cut off and repair cables. Workers in the front-line electrical service workshop can measure during the day, including when high-speed rail / Bullet train passes, which improves the timeliness and operability of detection.

What Are the Test Steps for Cable Failure
What Are the Test Steps for Cable Failure
The detection of cable fault generally goes through four steps: diagnosis, ranging, path finding and fixed point. 1. Diagnose the nature of cable fault, that is, determine the type and severity of fault, so that testers can suit the remedy to the case and select appropriate cable fault location and fixed-point methods. Measure the fault resistance with a megger and multimeter to determine whether the cable fault is high resistance or low resistance; Flashover or closed fault; Whether it is grounding, short circuit, disconnection, or a mixture of them; Is it single-phase, two-phase or three-phase fault. 2. Ranging cable fault location, also known as rough measurement, uses instruments to determine the fault distance at one end of the cable. The common fault location methods on the site include classical bridge method and modern traveling wave method. Use jcd-971 cable fault locator or cd-71 cable fault locator. 3. Use pd2000 cable path identifier or cd-12 / 22 cable path identifier produced by Zibo Electric Co., Ltd. for path finding. 4. Fault location acoustic magnetic synchronization method: use cd-81 cable fault locator to synchronize with the discharged electromagnetic signal and digitally sample the sound signal, The sound waveform at the moment of discharge is displayed on the LCD screen. The waveform can be maintained continuously for the operator to distinguish carefully, avoiding the disadvantage of transient sound. Moreover, the actual discharge waveform is obviously different from the surrounding noise. More importantly, the sound waveforms of multiple discharges are very similar. When the sound waveforms of multiple discharges are observed to be the same, It can be clearly judged that the discharge sound has been collected. Because the response range of acoustic measurement method is generally very small, when the discharge sound is heard, it is very close to the fault point, generally not more than 5m, or even within 1-2m
Cable Fault Detection and Search Method
Cable Fault Detection and Search Method
For direct short circuit or broken cable fault, the multimeter can be used for direct measurement and judgment; For indirect short-circuit cable fault and grounding cable fault, use a megger to telemeter the insulation resistance between core wires or the insulation resistance between core wires and ground, and judge the cable fault type according to its resistance value. The following describes the method of cable fault finding: zero potential method. Zero potential method is also known as potential comparison method. It is suitable for short cable core to ground fault. This method is simple and accurate, and does not need precision instruments and complex calculation. The measurement principle is as follows: connect the cable fault core wire in parallel with the comparison wire of the same length. When applying voltage ve at both ends of B and C, it is equivalent to connecting the power supply at both ends of two parallel uniform resistance wires. At this time, the potential difference between any point on one resistance wire and the corresponding point on the other resistance wire must be zero. On the contrary, the two points with zero potential difference must be the corresponding points. Because the negative pole of the micro voltmeter is grounded and equipotential with the cable fault point, when the positive pole of the micro voltmeter moves to the point when the indicated value is zero on the comparison wire, it is equipotential with the cable fault point, that is, the corresponding point of the cable fault point. S refers to single-phase knife switch, e refers to 6e battery or 4 No. 1 dry batteries, and G refers to DC microvolt meter. The measurement steps are as follows: 1) connect battery E on phase B and C core lines, and then lay a comparison conductor s with the same length as the fault cable on the ground. The conductor shall be bare copper wire or bare aluminum wire, with equal cross section and no intermediate joint. 2) The negative pole of the micro voltmeter shall be grounded, and the positive pole shall be connected with a long flexible conductor. The other end of the conductor shall be fully contacted when sliding on the laid comparison conductor. 3) Close the knife switch s, slide the end of the flexible conductor on the comparison conductor, and the position when the microvolt meter indicates zero is the position of the cable fault point. High voltage bridge method high voltage bridge method is to measure the DC resistance of cable core with double arm bridge, then accurately measure the actual length of cable, and calculate the cable fault point according to the positive proportional relationship between cable length and resistance. For direct short circuit between cable cores or short circuit point, the contact resistance is less than 1 & omega; The judgment error is generally not greater than 3m, and the contact resistance at the fault point is greater than 1 & omega; The resistance can be reduced to 1 & Omega by increasing the voltage and burning through; Next, measure according to this method. When measuring the circuit, first measure the resistance R1 between core wires a and B, R1 = 2RX R, where Rx is the phase resistance value from phase a or phase B to the cable fault point, which is only the contact resistance of the short contact. Then move the bridge to the other end of the cable and measure the DC resistance R2 between A1 and B1 core wires, then R2 = 2R (l-x) r, and R (l-x) is the phase resistance from A1 phase or B1 phase core wire to the cable fault point. After measuring R1 and R2, short circuit B1 and C1 according to the circuit shown in Figure 3, and measure the DC resistance value between B and C core wires, then 1 / 2 of the organization is the resistance value of each phase core wire, expressed by RL, RL = RX R (l-x), from which the contact resistance value of the fault point can be obtained: r = R1, r2-2rl table. Therefore, the resistance value of the core wires on both sides of the fault point can be expressed by the following formula: RX = (r1-r) / 2, R (l-x) = (r2-r) /2. After the three values of Rx, R (l-x) and RL are determined, the distance X or (l-x) between the fault point and the cable end can be calculated according to the proportional formula: x = (Rx / RL) l, (l-x) = (R (L-2) At the end of the cable, measure the capacitance currents IA1, IB2 and IC3 of the core wire of each phase to check the capacitance ratio between the intact core wire and the broken core wire, and preliminarily judge the approximate point of the broken wire distance. According to the capacitance calculation formula C = I / (2 & PI; Fu), when the positive voltage U and frequency f do not change, C is directly proportional to I. because the frequency of power frequency voltage is f (frequency) Constant, as long as the applied voltage is kept constant during measurement, the ratio of capacitance to current is the ratio of capacitance. If the total length of the cable is l and the distance of the core wire breaking point is x, then IA / ic = L / x, x = (IC / IA) 50. In the process of measurement, as long as the voltage remains unchanged, the reading of ammeter is accurate and the total length of cable is measured accurately, the measurement error is relatively small. The so-called sound measurement method is to find out according to the discharge sound of faulty cable. This method is more effective for the flashover discharge of high-voltage cable core to insulating layer. The equipment used in this method is DC withstand voltage tester. TB is high-voltage test Transformer, C refers to high-voltage capacitor, ve refers to high-voltage rectifier silicon stack, R refers to current limiting resistance, Q refers to discharge ball gap, and l refers to cable core. When capacitor C is charged to a certain voltage value, the ball gap discharges to the cable fault core, and the cable core discharges to the insulating layer at the cable fault, producing a loud and loud spark discharge sound. For open laying cables, it can be found directly by hearing. If it is buried electricity For cable, first determine and mark the cable direction. When searching, put the pickup close to the ground and move slowly along the cable direction. When the sound of Zi and Zi discharge is the largest, this is the cable fault point. Pay attention to safety when using this method, and assign special personnel to monitor at the end of the test equipment and the end of the cable. The cable fault locator produced by our company can not only measure the sound, but also To detect the magnetic signal, the signal strength is displayed visually and synchronously, which can locate the cable fault point faster and more accurately.
How Does the Cable Fault Tester Solve Various Cable Faults
How Does the Cable Fault Tester Solve Various Cable Faults
Cable fault tester is a comprehensive cable fault detection instrument. It can detect common faults such as high resistance flashover of cable, grounding device of high and low inductive load, short circuit fault, disconnection and looseness of cable. If equipped with point instrument specified by acoustic measurement Law, it can accurately measure the position of common fault point. It is very suitable for testing wires, cables and power cables with various models, specifications and different levels of working voltage. When testing the common faults of high resistance of cables with this set of machinery and equipment, the impulse flash method is selected. The common fault points must be charged and discharged and there is fire. During the detection, attention must be paid to prohibit the detection in the natural environment of high coalbed methane and high concentration combustible gas. In this case, please contact the manufacturer and use other methods for detection. Due to the continuous upgrading and improvement of instruments and equipment, the appearance design of instruments and equipment will be slightly different from the instructions, but the basic principles and steps of actual operation are basically the same. It is very important to show you that this tester is an integrated design scheme with solid program flow and high credibility. Therefore, when it is not connected with high-pressure machinery and equipment, it can safely compare the operating instructions, constantly learn and train the actual operation, and grasp its role without worrying about the harm to instruments and equipment. When there are all problems or stuck in the actual operation, it can be calibrated or standby to start again. We firmly believe that if we carefully study the instruction training of the cable fault tester, we will quickly grasp the actual operation and effect of the cable fault tester, understand the series parameters such as the cable fault test standard, and at least know the fault performance well and be handy in use.

[closed]Hey. I actually have the same setup at my work. I must say it does not have sense, if you use QC only to store defects. If you need bug tracking, you can stick with Jira. But you must understand that QC is tool dedicated for QA and it does much more. So it has sense to have Jira and QC if you (I mean QA at your work ) use all/most of QC features and you have Jira plugin that synchronizes defects between QC and Jira (I know about two plugins for Jira like that).[end of answer] If you are thinking 'but why the fck QA needs this stupid tool?' let me uncover a bit about QC for you.

I assume that most people (programmers) here know Jira, so I will uncover a bit about QC for you: P.S. It is a big tool, used properly works great, otherwise it sucksCan People Fool Benevolent Brother's 'Alibi Trackers' and Escape?As Angel pointed out, the system as you described is vulnerable to MitM and proxying attacks.For a secure alibi, we need the process to work like this:CT then knows these things:The following tricks are therefore avoided:Light speed is 300,000 km/sec, so 10km is 10/300,000 seconds, or about 33 microseconds. 66 for a round trip.The inaccuracy of cell triangulation is quite high: only to the nearest 1000m (about 3 light-milliseconds). So we can only calculate transmission times to the tower with an accuracy of about 3ms.Still, if a signal is delayed by 33 microseconds each way, that's 10 times the deviation we are willing to accept, and it means there's something up.With a system like this, proxying as described by Angel could work, but only within at most 1000m of where you are meant to be. You might be able to get a few more meters out of it, if instead of a single proxy, you put one on each triangulating cell tower, with a directional antenna to speak only to that tower. But it would not help much.Worse, the 1000m becomes MUCH less in areas where there are a lot of cell towers so triangulation is more accurate. And you can never tell how many towers there are, since they could be hidden. It would be in BB's interest to have lots of them.Benevolent Brother is not stupid.In the case of sophisticated tricks, no alarm would sound, no paddy-wagons get sent out. That's for people who just put on tin-foil hats and call it a day, not for sophisticated hackers. Benevolent Brother knows that everything like this is an arms race: once people know that their clever tricks do not work any more, they go to ground until they can develop cleverer and cleverer tricks. So it's important to let them think they are winning the arms race, so they do not develop better tricks.So, BB is unlikely to act overtly against someone using Angel's proxying trick, and instead will focus other surveillance methods on them until it's certain that everyone involved in producing the system has been identified, and he knows what they are planning. .. which he might even allow to continue. Since anyone who made proxying or spoofing equipment would be known, and all uses of the equipment would be of highest interest to BB, anyone getting hold of the equipment for a sophisticated trick would likely already be under very close surveillance before even using it.So, if you can not fool it, what can you do?I think the answer is obvious. They are tracking the movements of your head, your phone, your car, your public transport use, your creditcard use. They are using facial recognition on the surveillance cameras on every corner, and every cellphone and car is also a surveillance camera. They will know if you go anywhere you should not be.So if the smuggler's den is under a big farmer's market, take up an interest in fresh fruit and veg, and then you are just visiting the market. Well, it's the weekend, why not visit some museums and galleries? Why it's practically your civic duty to gaze upon those portraits and busts of Benevolent Brother every now and then.To evade the Alibi Tracker, you do not need fancy technology hacks. You need... an ALIBI
