Operation Precautions of Mine Cable Fault Tester

Coal mines and oil wells are large users of cables. Due to the harsh underground operating environment, the annual damage of various cables is relatively large. In order to save expenses and reduce production costs, each mine and oil well is generally equipped with its own cable maintenance department. However, due to the limitation of testing equipment, the maintenance of cables is often unsatisfactory; The AC / DC cable detection device independently developed and produced takes the high-voltage breakdown method as the principle, so that users can accurately find the cable damage point in the maintenance process. Moreover, the mining cable fault tester also has the function of testing after the old cable is repaired. Therefore, this device is an essential maintenance equipment for cable maintenance companies in coal mines and oil wells. 1. Insulating rubber pad shall be added before the equipment. 2. Operators shall wear insulating rubber shoes and insulating gloves. 3. The tested cable core and high-voltage terminal shall be firmly fixed with nuts to maintain good contact and avoid leakage and current increase caused by * * discharge. 4. Irrelevant personnel shall be prohibited from approaching the work site. 5. After one year of use, the transformer oil shall be subject to withstand voltage inspection in time, and the withstand voltage shall not be less than 30KV / 2.5in. 6. Regularly (depending on the strength of the equipment), carefully polish the surface of the discharge copper ball with zero sandpaper, and keep the surface and surrounding clean and free of dust. 7. The use effect of the equipment depends on the careful maintenance of the user, the continuous accumulation of operation experience, and the mastery of the relationship between the ball gap spacing and the discharge voltage of different cables.

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.
