Cable Identifier Manufacturers Popularize Science on Information Security of Power System
Cable Identifier Manufacturers Popularize Science on Information Security of Power System
China's science and technology are developing continuously and its economy is growing steadily. In this environment, the development speed of China's power industry is not the same as before. However, in today's society, facing the increasing demand for power in people's production and life, the power industry can ensure people's power consumption only by doing a good job in safe production. Now let the cable recognizer manufacturer popularize some knowledge about power system information security. In recent years, with the rapid development of power grid, especially power grid dispatching automation system, power dispatching control business has become the lifeblood of power system. According to the security protection regulations of power grid, power plant computer monitoring system and dispatching data network, the power control system must be effectively and safely isolated from the office automation system. The above-mentioned isolation means that the dispatching data network used by the power control system must be physically isolated from the public information network and the Internet, and a national power system information security protection system, security responsibility system and security joint defense system must be gradually established. The goal of power grid information security is to prevent the power grid, power plant computer monitoring system and dispatching data network from being attacked, prevent power system accidents caused by attacks, ensure the safe, stable and economic operation of power system, and protect the safety of important national infrastructure. Therefore, building the security protection system of dispatching automation system has become an important task of power grid dispatching automation in the future. Power grid information security has become an important link in the production, operation and management of power enterprises. 1、 Security protection scheme of main station of network dispatching automation system security protection strategy of main station of network dispatching automation system. Security zoning, network dedicated, horizontal isolation and vertical authentication are the basic strategies for security protection of power secondary system. Its core idea is two isolation, namely, effective and safe isolation between control system and office automation system, and physical isolation between dispatching data network, public information network and Internet. 2、 The basic principle of security protection of power real-time data network system. In theory, although the power real-time data network system with absolute security and confidentiality can not be established, if some reasonable principles are followed at the beginning of construction, the corresponding security and confidentiality will be greatly improved. When designing the security mechanism of power data network, we should follow the following principles from the perspective of Engineering Technology: among them, the integrity principle of network information security system comprehensively considers the factors such as security protection, monitoring and emergency recovery. Because the security and confidentiality of network information can not be guaranteed, it is required that when the network is attacked and damaged, the service of the network information center must be restored as soon as possible to reduce losses. Therefore, the security protection mechanism, security monitoring mechanism and security recovery mechanism of information security system should be included. Principle 2: Barrel Principle of security and confidentiality; It is necessary to consider the balance and comprehensive security protection of network data and information. The cable identifier manufacturer believes that it is a necessary prerequisite for designing the information security system to fully, comprehensively and completely analyze, evaluate and detect the security vulnerabilities and security threats (including simulated attacks) of the system.
Pulse Method of Cable Fault Tester
Pulse Method of Cable Fault Tester
Cable plays a very important role in daily life. If the cable fails, find the fault point in time and then repair it. Cable fault detector is the preferred tool for cable maintenance. It can accurately find the fault point, and then the construction personnel can carry out maintenance quickly, which is very effective in improving work efficiency. Today, we follow the cable fault tester manufacturer to understand what pulse method is. Working principle of power cable fault tester power cable fault tester consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the test end. The cable fault locator determines the location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, a pathfinder shall be used to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. The working principle of the application of arc reflection method (secondary pulse method) in cable fault location: firstly, a high voltage pulse with a certain voltage level and energy is applied to the faulty cable at the test end of the cable to make the high resistance fault point of the cable break down and burn arc. At the same time, add the low-voltage pulse for measurement at the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and reflects on the surface of the arc. When arcing, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will change obviously in impedance characteristics, so that the waveform of flashover measurement becomes a low-voltage pulse short-circuit waveform, making the waveform discrimination particularly simple and clear. This is what we call the secondary pulse method. The received low-voltage pulse reflection waveform is equivalent to the waveform of a complete short circuit between the core and the ground. Superimpose the low-voltage pulse waveform obtained when releasing the high-voltage pulse and when not releasing the high-voltage pulse. The two waveforms will have a divergence point, which is the reflected waveform point of the fault point. This method combines low-voltage pulse method with high-voltage flashover technology, which makes it easier for testers to judge the location of fault point. Compared with the traditional test methods, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into a simple low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. The multiple pulse method adopts the double impact method to prolong the arc burning time and stabilize the arc, which can easily locate the high resistance fault and flashover fault. Cable fault tester manufacturers believe that the multiple pulse method has advanced technology, simple operation, clear waveform and fast and accurate positioning. At present, it has become the mainstream positioning method of high resistance fault and flashover fault. The multiple pulse method is an upgrade of the secondary pulse method. The method is to first measure the reflected waveform of the low-voltage pulse without breaking through the fault point of the measured cable, then impact the fault point of the cable with the high-voltage pulse to generate an arc, trigger the medium voltage pulse when the arc voltage drops to a certain value to stabilize and prolong the arc time, and then send the low-voltage pulse, Thus, the reflected waveform of the fault point is obtained. After the superposition of the two waveforms, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stabilize and prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse method. Compared with the secondary pulse method, the triple pulse method does not need to select the synchronization time of arc burning, and the operation is also more simple. Cable fault tester is a comprehensive cable fault detection instrument. It can test the high resistance flashover fault, high and low resistance grounding, short circuit, cable disconnection, poor contact and other faults of the cable. If equipped with the acoustic method pointing instrument, it can accurately determine the position of the fault point. It is especially suitable for testing power cables and communication cables of various models and different levels of voltage. The above is the introduction of the pulse method by the cable fault tester manufacturer, hoping to provide help to those in need.

The cable tracker helps us find the best angle for watching TV and even lets us pause while we cook dinner.Cable tracking devices can help you with many tasks around your house like finding the right position for an antenna or measuring distance between two points. They are inexpensive and easy to use.The specifications of cable trackerCable tracker is a device used to measure the distance between a point and a cable laying on the ground. It consists of a rod, an "O" ring, and an attached meter.The cable tracker was developed by Alfred J. Butler in 1883 and patented in 1885. It was originally meant for measuring the distance between two points on a long piece of wire. However, it became popular after being adapted for use with cables.A favorite use for this device is to measure the height of trees by running it through each tree's trunk, taking care not to come in contact with the metal rods inside which could damage them or cause rusting that would eventually lead to breaking off branches.The product instructions of cable trackerThe product instructions of cable tracker is a website that helps customers to choose the perfect cable and subscription for their needs.

State of the Industry Report: Cable TV Tracker
The introduction of cable tracker is one of the most significant developments in the television industry. The introduction of cable tracker every month to track and manage all cable channels was a step forward in the digitalization of TV. Now you can directly track your favorite shows, find out which shows are trending and which ones are on their way down, take action on new shows that will be available to watch later, see what is happening with your favorite channel and more.Cable providers have become the center of a new world, and there are many companies that are trying their best to be in the leadership. But it's not easy, because there is a lot of competition and they have to adapt quickly. In this article we will take a quick look at some of the most interesting products.Cable providers have long been in the business of delivering content to their customers. With the increasing speed of data availability and the rise in internet usage, they need to determine who is using their services and how much they are paying for it.With the rise of cable companies, most of us have been exposed to cable television. Since we are the ones that pay for these services, we should be able to get information about them as well.1. This section is dedicated to all cable providers, whether it is a local TV channel or a national cable company. What are the best ways to use your online customer database? What are the different methods of collecting information from your customers? Which data should you collect and how do you determine what kind of information to collect?2. This section is dedicated to all cable providers that want to improve their customer service by using data analytics and analytics software. How can they use this data in order to increase the overall efficiency for their customers? How can they improve their tracking abilities so that they will be able to better understand their customers' needs and wants? How can they identify trends in their customer's behavior and work towards improving it with actual data instead of guessing at what people want and need?Cable providers have a lot of cable channels that they have to pay for, and instead of spending too much money on them, they would like to find some alternatives.Unfortunately, they are not allowed to stream the content on their own servers anymore, since copyright infringement is punishable by law. Someone else has to be responsible for it, and that someone is the Cable Tracker.The Cable Tracker allows people who own a cable provider account or a satellite provider account (as long as they can see the satellite channel) to browse every single cable channel in their area and tell them what has been streamed on it. The user can easily create an alert if there is something that he thinks he should be aware about: when a movie is being played or if someone has accessed his account without his permission. After allWhat is Cable Tracker?Cable Tracker is a web based tool that allows cable providers to track viewer’s viewing habits across all of their channels. It provides them with a dashboard where they can view and analyze their subscriber’s viewing history.It seems like cable providers are focused on providing quality TV service to their customers. However, they are not the only ones to provide this service. Comcast, Aereo etc have faced similar issues of poor quality content that is being provided by their competitors even after paying for the content.There are 2 essential benefits of using these units:1. No need to spend money on continuous deployment and roll out of new technologies as there will always be a market for cable operators to offer their services. The same model can be replicated for any other industry or business sector because it doesn't require any investments in software development and deployment which can cost millions of dollars in order to implement new technology successfully. This also means that the overall investment required by an organization for new technology is minimal compared with other products or services thatThe idea is that a cable company will pay for the services of a cable picker who will go to different locations and collect the cables that are likely to go through a specific area.
Principle and Application of Cable Oscillation Wave Test
Principle and Application of Cable Oscillation Wave Test
1、 Principle of cable oscillation wave test through cable oscillation wave test can not only diagnose the overall insulation of cable, but also test partial discharge and locate defects. The principle is LCR damping oscillation principle. On the basis of completing the cable pressurization, a damping oscillation voltage wave is formed through the built-in high-voltage reactor, high-voltage solid-state switch and the test cable. A sinusoidal voltage wave similar to the power frequency is applied to the test cable to excite the partial discharge signal at the potential defect of the cable. Based on the pulse current method, the partial discharge signal is detected with high sensitivity, and the detection, acquisition and upload of partial discharge signal are completed with high-speed data acquisition equipment. The single test process is about one minute, with high test efficiency and no damage to the tested cable. On the basis of obtaining the partial discharge data, the data analysis software automatically completes the cluster analysis and traveling wave positioning, which is convenient for users to comprehensively evaluate the cable state. 2、 Purpose: the cable oscillation wave test standard passes the field test to check the insulation condition and internal partial discharge condition of the cable without damaging the insulation of the cable itself, so as to evaluate the cable insulation. The high voltage unit of cable oscillation wave test can generate oscillation wave high voltage signal, and the high voltage generator can generate any high voltage of 0-30kv; For the partial discharge test device with no blind area from the partial discharge signal, there is no blind area, and it can detect the cable below 250m for partial discharge test; One laptop can be used for control; External safety control units such as operation software (Chinese / German / English version); Analysis software (Chinese / German / English version); A 7.5m high-voltage connecting line without partial discharge, with anti falling off safety design; The partial discharge under system voltage is less than 1pc III. cable oscillation wave test case analysis through the above understanding, let's talk about examples below, so that you can better understand its actual field use. Firstly, connect the test line according to the instructions, and then turn on the power supply. The waveform diagram during the test is as follows: through a waveform analysis, we found a damaged gap in the outer sheath at about 132M in the field survey, which is the cable insulation damage caused by external construction force. After disassembly, the main insulation is damaged
