    How to Prevent a Spark at Relay Contacts?

    The relay contacts’ jumping or switching on/off will cause the change of inductive load and further gas discharge. The current of relay contact on-off is small, there will be no electrical arc between contacts, but there will be a spark at the relay contacts. Due to the existence of inductance in the contact circuit, there will be overvoltage on the inductance when disconnecting the contact circuit. Together with the voltage supply in the contact gap, the contact gap that just separates a little will be broken down and discharged. Limited to energy, there will only be spark discharge. The conversion of capacitance between contacts and energy in inductance makes spark discharge disappear and reappear, becoming a high frequency signal, which will be crosstalk to related circuits by means of high frequency radiation, wire transmission and distributed capacitance, forming interference signals. Furthermore, spark discharges can also damage relay contacts and shorten the service life of contacts, so that sparks may ablate contact surfaces and make the surface uneven, resulting in failure of relay poor contact.

    How to Maintain UPS Battery Life?

    When using uninterruptible power supply (UPS) system, people tend to unilaterally believe that there is no need to maintain batteries. However, the data show that there is about one third UPS host failure or abnormal operation caused by battery failure. Therefore, it is more and more important to strengthen the proper use and maintenance of UPS battery for prolonging the service life of batteries and then reducing the failure rate of UPS system.

    Why is the Neutral Wire So Important?

    The impedance of N-wire is at the milliohm level, and its unbalanced voltage of load neutral point is the voltage drop of N-wire current on N-wire impedance with small value. Even if the three-phase load is seriously unbalanced, it is enough to clamp the neutral point potential of load on the neutral point potential of power supply. While the ground resistance is at the ohm level, which is several hundred times larger than the N-wire impedance, so it is impossible to clamp the neutral point potential of load on the neutral point potential of power supply.

    How to Increase Efficiency of Step Up/Step Down Transformer?

    Step up or step down transformer is an important part of power grid operation, it's of great significance to the stable operation of the power grid. It meets different power demands by adjusting current and voltage. Once a transformer fails, it will cause great losses to the whole power grid, and further affects the normal operation of industrial production. In order to ensure the efficient operation of transformers, it is necessary to carry out a comprehensive management of the whole process of installation and application, thus reducing potential safety hazards and improving operational efficiency.

    Automatic Voltage Stabilizer Buying Guide

    Before purchasing a voltage stabilizer, you'd better determine the reverse range and frequency of household voltage. For instance, if your voltage is pulled to about 80V and the input range of your voltage stabilizer is between 140 V and 260V, it will not work as you wish. Therefore, voltage stabilizers should be selected according to the power supply range of the service environment. It is recommended to choose a broadband voltage stabilizer.

    How to Select a Right Magnetic Flow Meter?

    Nowadays, the magnetic flow meter (electromagnetic flow meter) has been widely applied to measuring of industrial sewage or wastewater. With a high precision and a long service life, the magnetic flow meter is the top choice for the environmental measuring industry. To choose the correct magnetic flow meter can five fuller play to the magnetic flow meter for specific purposes. Generally, the selection of the magnetic flow meter is based on the following factors including chemical attributes of the fluid medium, pipeline diameter, flow range, liner material, electrode material and output signal.

    How to Calculate AC Contactor Current Rating for Motor?

    The AC contactor has found wide applications in the motor-controlled circuit. It is no exaggeration to say that the electric drive of most motors cannot be separated from the control of the AC contactor. Many electricians are very familiar with the AC contactor for their frequency use or maintenance of it. How should we calculate the AC contactor rating for the motor or other equipment and make a right choice? Let us take a look at it.

    How Magnetic Flow Meter Works?

    A magnetic flow meter, mag meter, or electromagnetic flow meter is a kind of instrument which measures the volume flow rate of the conductive fluid based on the principle of Faraday's Law of Electromagnetic Induction. With a large measurable flow range, the ratio of the maximum flow rate to the minimum flow rate maintains above 20:1. The mag flow meter is suitable for wide range of industrial pipe diameter, and the maximum can reach up to 3m. The output signal and the measured flow are linear, and the magnetic flow meter has high measurement precision. It can effectively measure the flow rate of fluids with a conductivity more than 5μs/cm, such as acid solution, alkaline solution, saline solution, water, sewage, corrosive liquid, mud, ore pulp, and paper pulp. Nevertheless, the electromagnetic flow meter cannot be used to measure the flow of gases, steam and purified water.

    Difference Between Current Transformer and Potential Transformer

    The instrument transformers like current transformer and potential transformer (also called voltage transformer) are both used for measuring devices, which have a similar working principle to transformers. The current transformer can reduce the high current to low current, while the potential transformer steps down the high voltage to low voltage for measuring the circuit or in the power distribution. They both separate the measurement circuit from the high-voltage grid to protect safety of the personnel.

    How Does a Combustible Gas Detector Work?

    Combustible gas has certain characteristics of diffusion. In order to prevent the accidents caused by combustible gas leakage, the key lies in effectively controlling its continuous diffusion. Moreover, flammable gases will spread quickly driven by external forces. As a result, burning and explosion will take place. How to prevent the occurrence of this kind of accidents? What we need to do is often detecting the concentration of combustible gas whether it exceed the standard. Once the concentration exceeds the standard, give an alarm quickly and we take actions immediately. Here combustible gas detector plays an important role.
    A combustible gas detector is a detector that monitor the concentration of single or multiple combustible gases and give an alarm. Combustible gas detectors are mainly divided into two types, catalytic type and infrared optical type base on the working principle.

    FAQ-Step Up/Step Down Transformer

    Q: What is a transformer?
    A: 
    A transformer is a device that step up or step down the voltage in an AC circuit. It converts the voltage of any value into the voltage value we need at the same frequency to meet the requirements for the delivery, distribution and use of electrical energy. For example, the electricity generated by the power plant has a low voltage level, and the voltage must be raised to be transported to a remote power consumption area. And the power supply area must be turned down to a suitable voltage level to supply power equipment and daily power equipment.
