Cable Grounding Troubleshooting and Precautions
Cable Grounding Troubleshooting and Precautions
There are three main reasons for cable grounding fault. First, cable manufacturing defects are unqualified products; Second, poor operating environment, natural aging and external damage; Third, the installation is not standardized and the wiring is rough. There is only one root cause of grounding fault --- the insulating material of the cable. China's large-scale ground power stations are generally located in the West. These places are generally desert, saline alkali land, large temperature difference in the daytime, serious rat damage and very humid environment. For cable buried laying, the filling and excavation requirements of cable trench are relatively high; The operating environment of the distributed power station cable is no better than that of the above ground. The cable will bear a very high temperature, which is measured and controlled by technicians. The roof temperature can even reach the high temperature of 100-110 ℃. The fire and flame retardant requirements of the cable and the high temperature have a great impact on the insulation breakdown voltage of the cable. Therefore, the following points should be considered in the type selection design: 1. The insulation performance of the cable 2. The moisture-proof, cold proof and weather resistance of the cable 3. The heat-resistant and flame-retardant performance of the cable 4. The laying mode of the cable 5. The conductor material of the cable (copper core, aluminum alloy core and aluminum core) 6. The Section specification of the cable
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.

Volume: 225 × one hundred and sixty-five × 125mm38. Weight: 2kg1 traditional cable fault detection method 1.1 measuring resistance bridge method this method has hardly changed for decades. For short circuit fault and low resistance fault, this method is very convenient. The bridge method is based on the principle that when the bridge is balanced, the product of the corresponding bridge arm resistance is equal, and the length of the cable is directly proportional to the resistance. 1.2 low voltage pulse reflection method low voltage pulse method, also known as time domain reflection method (TDR), means that the pulse reflector independently measures the low resistance and open circuit faults of the cable without passing through the high voltage impactor. 1.3 pulse voltage sampling method pulse voltage sampling method, also known as impulse high voltage flashover method, is a test method for measuring high resistance leakage and flashover faults. Firstly, the cable fault is broken down under the DC or pulse high voltage signal, and then the distance is measured by recording the time required for the discharge pulse to go back and forth between the measuring point and the fault point. Pulse voltage method mainly includes DC high voltage flashover (direct flashover method) and impulse high voltage flashover (impulse flashover method). 1.4 traditional method of cable fault location ①acoustic measurement method this method uses the breakdown and discharge sound of the fault point during high voltage impact to locate the * *. ② Dear customers: Hello, our company is a high-quality development group with strong technical force, providing high-quality products, complete solutions and superior technical services for the majority of users.

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.

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.
