Advantage Analysis of Cable Fault Tester

With the development of the market, cable fault tester is mainly divided into common and three pulses. What are the advantages and functions of these two kinds? Yuange will explain them to you. [functional advantages of common cable fault tester] 1. It can measure high and low resistance faults of all cables below 35KV, with wide adaptability. 2. It has user-friendly software and full Chinese menu. Key definition is simple and clear. The measurement method is simple and fast. 3. Excellent fault detection success rate, test accuracy and test convenience. As the display terminal, the 4.8-inch color LCD touch screen has strong data processing ability and friendly display interface. 5. Sampling high voltage protection measures are provided. The test instrument will not crash and damage in the impact high-pressure environment. 6. With computer communication interface, it is convenient to save data and graphics in the computer. 7. No test blind area. 8. The built-in power supply can test the open circuit and low resistance short circuit faults of the cable in the environment without power supply. [functional advantages of triple pulse cable fault tester] 1. It can measure high and low resistance faults of all cables of 35kV and below, and has a wide range of adaptability. 2. The "three-stage pulse method" and "three-stage multiple pulse method" are adopted. At the same time, it also has the traditional high-voltage flashover method and low-voltage pulse method. 3. Any high resistance fault presents simple waveform characteristics similar to low voltage pulse short circuit fault, which is very easy to interpret. 4. It has user-friendly software and full Chinese menu. Key definition is simple and clear. The measurement method is simple and fast. 5. The central control unit is used for one key control to trigger three levels of signal output in sequence to ensure safety and success rate. The central control unit can prompt the operation steps and monitor the work process. 6. It has the function of test waveform storage, which can easily store the waveforms tested on site in the instrument according to the specified sequence for call and observation at any time. A large number of field test waveforms can be stored. 7. The measured fault point waveform and good phase full-length open circuit waveform can be displayed on the screen at the same time for the same screen comparison and superposition comparison, and the fault distance can be judged automatically. 8. 11 inch bright color touch LCD display, with strong data processing ability and friendly display interface. 9. Sampling high voltage protection measures are provided. 10. With 232 computer communication interface and USB communication interface, it is convenient to save data and graphics in the computer. 11. The built-in power supply can test the open circuit and low resistance short circuit faults of the cable in the environment without power supply. [functional advantages of cable fault locator] 1. The data display part adopts a highlighted 4.3-inch OLED color LCD to make the display interface clearer. 2. The function and parameter adjustment part adopts a one key programmable pulse coding keyboard, which makes the operation panel more concise and the operation more convenient. 3. The instrument will collect and display the waveform of the audio part in real time. The distance of the fault point can be roughly observed by observing the repetitive waveform characteristics and distance axis, and the operator is not easy to be tired. 4. There are single and continuous modes in the acoustic magnetic fixed-point mode. If the discharge frequency is too fast and the gap time is too short, the user can select the single mode to carefully analyze the relevant data such as the primary discharge waveform, and the waveform page turning is supported in the single mode. 5. In the acoustic signal acquisition, four filter bands are adopted, including low frequency band, intermediate frequency band, high frequency band and full frequency band, which can be selected by the user according to the actual situation on site. 6. The step voltage part adopts waveform display to continuously sample and refresh the signal, so that the user can enhance the continuity analysis of the signal and the resolution of the jump signal. 7. The step voltage part is subdivided into multiple gears, and the large signal is automatically attenuated during the adjustment process to ensure that the display signal is not limited when the maximum voltage amplitude within the test range is input. 8. FIR digital filtering technology is adopted for audio filtering, which makes the characteristic frequency band more obvious and the filtering performance better. 9. Display the distance of the fault point. The distance of the fault point can be displayed within 0-25m. 10. In continuous mode, the compressed waveform within 15m can be displayed. In single mode, the waveform within 15m can be analyzed.

5 Reasons a Voltage Detector Pen Is Good for You
A voltage detector is a quick and inexpensive method to check the presence of voltage in an AC circuit, switch or socket without actually working with it. Also known as a voltage rod, rod, sniffer or pin, a voltage detector clings to a shirt pocket and beeps or glows when it detects voltage in a conductive part of the insulation.Voltage detectors are used to repair electrical circuits, detect live neutral wires and in other situations where you need to verify the presence of electric current. These types of voltage detectors are designed for the non-contact detection of electrical circuits in residential, commercial and industrial buildings. Random contact with live electrical conductors is no problem, and the detector evaluates the voltage level in the electrical safety category for which it is used.The voltage tester Klein Tools ET40 is ideal for checking regular electrical cables, door bell sockets, lights and other devices. It has functions for displaying positive and negative DC polarity and is able to detect DC voltage currents as low as 1.5 V. In addition to detecting standard voltages and low voltages, voltage detectors and LED testers can also detect rated voltages.A good voltage tester not only saves you time, but also gives you the certainty that your electricity prices are normal. The best voltage detector pins operate in a wide voltage range and are able to provide acoustic and acoustic feedback when detecting voltage. They are small enough to be transported and provide a precise reading that tells the user whether voltage is present or not.Reinforced electronic testers (also called electrical testers, pins and voltage detectors) rely on capacitive currents to detect changes in the electric field of an energy-charged object. Non-contact voltage testers (test pins, voltage sensors, voltage testers and pins they know) are the safest way to ensure that an electrical conductor has no voltage without touching it or suffering an electric shock. They work by detecting changes in an electric field surrounding an object conducting alternating or alternating current.Non-contact testers allow you to check the voltage of a wire or device without having to touch the wire or part. A voltage tester can be used to test the presence of voltage when a multimeter cannot detect it and to measure and display the exact amount of available voltage. These testers are designed to detect the main voltage and do not provide any indication of low voltage control circuits used in the bells or HVAC controls.A further limitation is that DC voltage can not be detected with this method because DC currents do not flow in a uniform state through capacitors and non-contact testers that detect electrical fields cannot be activated. You cannot detect voltage through shielded or armoured cables, and this is a basic limitation due to the Faraday cage effect. A TONG or AMmeter detects changes in magnetic fields, while a detector uses current flowing through the wire in question, and it senses alternating electric fields emitted by AC conductors.Given the variety of products in the contactless voltage tester category, you can expect different types of NCVTs, but you can imagine that there are more contactless DC voltage testers and contactless DC voltage testers than there are regular DC testers on the market. Remember to use a quality insulation resistance tester when you need to measure the insulation around your circuit. You want a non-contact voltage tester that comes with a hook so that you can put it in your shirt pocket.I call it the voltage sniffer, but the technical name for it is the capacitive voltage sensor. It is supplied with an alligator clip, which is interchangeable with test cables, and a holster to keep it handy. It uses black magic to determine whether wires are live or not, and it is 100% reliable at all times.
