Introduction to Cable Fault Locator
Introduction to 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.

Knowledge About Frequency Counter & Crystal Tester Kit Circuit & Schematic
Knowledge About Frequency Counter & Crystal Tester Kit Circuit & Schematic
1. KSWG of frequency counter & crystal tester kit circuit & schematicKSWG (96.3 MHz) is a commercial FM radio station licensed to Wickenburg, Arizona. It is owned by Barna Broadcasting Company and airs a classic country radio format, using the moniker "Real Country 96.3." The station is considered a rimshot broadcaster because its transmitter is more than 50 miles from downtown Phoenix, Arizona. KSWG's signal is primarily heard in northwest suburbs of the Phoenix market.The studios and offices are on West Wickenburg Way in Wickenburg. The transmitter is off South Vulture Mine Road, also in Wickenburg.------2. History of frequency counter & crystal tester kit circuit & schematicKFMA, KMEO and KBSZToday's KSWG began life in September 1992 on 93.7MHz as modern rock station KFMA. The station was owned by Harold Shumway alongside KTIM 1250 AM, and as KFMA, it was run by former KUPD/KUKQ general manager Lloyd Melton. However, when KEDJ-FM was born months later, it pushed KFMA, with its partial-market signal, out of the format. Early in 1993 KFMA became KMEO, an easy listening music station using call letters made famous in Phoenix by KMEO-AM-FM (now KIDR and KMXP); Melton sued Shumway in Maricopa County Superior Court.On March 24, 1995, KMEO flipped to new age music as KBSZ "The Breeze". Geoff Stirling, a new age enthusiast and Canadian-American media mogul, had an unspecified stake in the station. KBSZ also made moves to increase its coverage; it picked up use of a translator from KEDJ at 96.3MHz, improving its signal in metro Phoenix. It also moved its main signal to 94.1 with increased power in March 1996; the KBSZ call letters also turned up on the AM station on March 1, 1996, where they remain today (even though the station has moved across the Valley to Apache Junction). However, low audience turnout for the last concert the station sponsored and low ad sales prompted Circle S to move in a new direction.KSWGIn July 1996, KBSZ-FM became KSWG "94 Country" with a classic country as KSWG. It was one of two new country stations in the Phoenix market that month, alongside KXLL/KBUQ "Young Buck Country".In 2006, KSWG relocated from 94.1 to 96.3. The station was sold to Barna Broadcasting in 2012.In 2017, an interference dispute lodged by KSWG against KXEG translator K241CS (96.1) prompted a counter-filing alleging that the facility on which KSWG was operating was not the one it was licensed for; it was directional toward Phoenix, and the tower was 57 feet (17m) higher than authorized.------3. Transfusion therapy (Sickle-cell disease) of frequency counter & crystal tester kit circuit & schematicRed blood cells (erythrocytes) from donors contain normal hemoglobin (HbA), and transfusion of normal red blood cells into people with sickle cell disease reduces the percentage of red cells in the circulation containing the abnormal hemoglobin (HbS). Although transfusion of donor red blood cells can ameliorate and even prevent complications of sickle cell disease in certain circumstances, transfusion therapy is not universally beneficial in sickle cell disease.------4. Practical Mechanics of frequency counter & crystal tester kit circuit & schematicPractical Mechanics was a monthly British magazine devoted mostly to home mechanics and technology. It was first published by George Newnes, Ltd., in October 1933, and ran for 352 issues until the magazine's termination in August 1963. Practical Mechanics was edited by Frederick J. Camm until his death in 1959.With an emphasis on things its readers could reasonably construct themselves, the magazine featured numerous articles on how to build things around one's house, such as a sink or bathtub. It also regularly featured more fanciful articles on how to build things with less obvious applications around the home, for example a Geiger counter, or an aeroplane for 25 (not including the cost of an engine).The early issues were in black and white. The magazine began printing in color at an unknown date.Practical Mechanics was one of a number of DIY British publications, including Practical Householder, Practical Motorist, and Practical Wireless, also founded by Frederick J. Camm.------5. CKHR-FM of frequency counter & crystal tester kit circuit & schematicCKHR-FM is a Canadian radio station that broadcasts community radio programming on the frequency 107.3 FM in Hay River, Northwest Territories.The station is owned by the Hay River Community Service Society. The current volunteer station manager is Mark Lundbek. Aside from broadcasting, Lundbek is also an internet professional who specializes in website design, social media management, telecommunications, video game development and international counter-terrorism.------6. WLTY of frequency counter & crystal tester kit circuit & schematicWLTY is a variety hits radio station licensed to Cayce, South Carolina and serves the Columbia, South Carolina market. The iHeartMedia, Inc. outlet is licensed by the Federal Communications Commission (FCC) to broadcast at 96.7MHz with an effective radiated power (ERP) of 9kW. Its studios are in Columbia (west of the Congaree River) and the transmitter is east of downtown Columbia------7. Types of transfusion therapy of frequency counter & crystal tester kit circuit & schematicThere are two main types of transfusion, simple red cell transfusion and exchange transfusion.Simple transfusionInvolves transfusing red blood cells without removing any of the patients blood. It is used when the patient's hemoglobin is much lower than normal, for example an aplastic crisis.Exchange transfusionExchange transfusion involves removal of the patients blood and replacement with donor red blood cells. It is used to treat life-threatening complications of sickle cell disease such as stroke or acute chest crisis.There are three main benefits of an exchange transfusion compared to a simple transfusion, these relate primarily to the ability to remove hemoglobin S containing red blood cells:Higher percentage of normal (donor) hemoglobin (HbA) containing red cells after the transfusionLarger volumes of donor blood can be given without increasing the hematocrit to levels that excessively increase blood viscosityReduced net transfused volume of red blood cells, which reduces iron overload.However, there are also potential risks associated with an exchange transfusion:Red cell alloimmunization due to increased donor exposureHigher costsNeed for specialized equipmentNeed for good venous access.Automated red cell exchangeThe exchange is performed using a machine (pheresis). This method rapidly and substantially reduces the concentration of sickle cells within the blood without increasing the overall hematocrit or blood viscosity.Manual red cell exchangeThe exchange is performed manually. It refers to manually phlebotomizing a percentage of the patients blood prior to or concomitantly with giving a red cell transfusion.Frequency of red cell transfusionsRed cell transfusions can be further classified as episodic or chronic.Episodic transfusionEpisodic transfusion is used either acutely in response to a complication of sickle cell disease such as acute chest syndrome or to prevent complications prior to surgery.Chronic transfusionChronic transfusion is used when sustained, low levels of HbS are needed to prevent sickle cell-related complications, most commonly stroke in children.

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.

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.
Introduction to Relevant Knowledge of Power Cable Pathfinder
Introduction to Relevant Knowledge of Power Cable Pathfinder
Electricity has an incomparable position in our daily life. It can be said that without electricity, our life will be a mess. However, the power demand is so large that the cable will inevitably fail. In order to remove the fault in time, relevant detection equipment is essential. Today, Xiaobian will introduce you some relevant knowledge about power cable Pathfinder. In the power industry, due to the outgoing fault of power cable, it is necessary to determine the fault location. At this time, in order to accurately find the fault location and reduce the excavation quantities and search time, it is necessary to use the intelligent cable path detector to quickly and accurately determine the cable path. There are many communication cables and TV cables in the communication industry. When these cables have faults and need to be detected, their paths also need to be determined. In order to avoid damaging underground pipelines during excavation, reduce unnecessary economic losses and speed up the project progress, it is necessary to accurately know the location of buried pipelines. Due to the incomplete or missing data of underground pipelines in the past, the urban construction and planning department can not accurately grasp the distribution of pipelines under the city, resulting in many problems in the process of urban planning. In this case, the path of underground pipelines should be detected again and saved. Because the cable is directly buried or buried in the cable trench, it is difficult to observe the cable path direction when the GIS data is incomplete. Therefore, after pre positioning the cable, the next step is to use the Pathfinder to find the cable direction and find out the approximate location of the fault point, and the precise point at the back is meaningful. At present, the commonly used cable path detection method is audio induction method, that is, add audio current signal of specific frequency into the cable, the current signal generates magnetic field signal around the cable, sense the magnetic field signal with an induction coil, convert it into sound or waveform after filtering, and display it through earphone or display, Where there is sound or waveform display is where the cable passes, so as to detect the cable path. When using audio induction method to detect cable path, if you want to get a strong magnetic field signal on the earth surface, you must make some current pass through the earth, otherwise the magnetic field signal may be weak. The power cable Pathfinder is a device for detecting the underground cable path. It not only has the function of the old underground cable path detector, but also has some new functions, and has made a certain technical breakthrough. 1. Peak mode. In this mode, the relative position between the cable and the operator can be judged and the direction in which the operator should move can be indicated, Then find the buried location of underground cables. 2. Valley value mode, which has compass function, can judge the deflection direction between the operator and the cable, and prompt the operator to correct his direction in time until the position of the cable is found. 3. The automatic search and locking frequency function can search the signal frequency when the frequency input is unknown, so as to determine the access frequency and lock it. 4. Current and depth display can display the current and buried depth of underground cables in real time. 5. GPS positioning: when the location of the cable has been determined and the current geographic location information of the cable needs to be recorded, you can select the GPS positioning function to record the geographic location information of the current cable, and finally upload it to the computer for cable data management.
