Half Step: Activate one coil and then afterwards two simultaneously. As a result, the rotor moves half a step due to the directly aligned position with one active coil to split alignment with two active coils. This method adds additional steps in the motor’s rotation, significantly enhancing its resolution. Microstep: Activate coils using sine wave pulses in a sequence so the motor can start moving in small steps. This approach will provide the highest resolution amongst the major ways mentioned above to control a stepper motor. It will divide the rotor’s full steps into 256 steps. Microstepping will ensure the smooth and consistent movement of the rotor, minimizing noise, vibration, and wear on motor parts. Due to these advantages, micro stepping is the most known activation mode for stepper motors nowadays amongst contemporary applications.

Standards and Regulations – To reduce the negative effects of stepper motors, environmental laws, and industry standards are of the utmost importance. These rules generally dictate the usage of hazardous materials, acceptable energy consumption limits, and recycling and disposal criteria.

High tech ammonia water sensor factory

Top ammonia water sensor manufacturer: What’s the water color ? Colour is important parameters in water . Water is a colorless, odorless, and odorless transparent liquid in natural. When certain substances exist in the water (such as some soluble organic substances, some inorganic ions, and colored suspended particles, etc.), the water may become colored. The situation, that is, the water will appear a certain color is the chroma. Generally, 1 mg / L of platinum in the form of chloroplatinic acid ions is called 1 PCU. Find extra information on water quality sensor.

Within the power station, the aim of water and steam control is to minimize contamination of the circuit, thereby reducing corrosion as well as cutting down the risk of the formation of harmful impurities. Therefore it is very important to control the quality of water to prevent the deposits on turbine blades by Silica (SiO2), reduce corrosion by dissolved oxygen (DO), or prevent acid corrosion by Hydrazine (N2H4). Measurement of water conductivity gives an excellent initial indication of falling water quality, analysis of Chlorine (Cl2), Ozone (O3), and Chloride (Cl) used for control of cooling water disinfecting, an indication of corrosion, and detection of cooling water leaks in the condense stage.

Fourth step is distribution ,we have to measure pH,turbidity,hardness,residual chlorine,conductivity(TDS),then we can know the potential risks or threaten to public heath on time.the residual chlorine value should be over 0.3mg/L when be piped out from drinking water plant, and over 0.05mg/L at end of pipe network.turbidity must less 1NTU,pH value is between 6.5~8,5,pipe will be corrosive if pH value is less 6.5pH and easy scale if pH is over 8.5pH.

What is eddy current? What are the disadvantages of eddy current generation? Eddy current refers to a kind of current generated in the conductor, which is the induced current caused by the change of the magnetic field. The eddy current forms a circular current flow path in the conductor, and this current forms a motion state similar to an eddy current inside the conductor, so it is called an eddy current. The generation of eddy currents has the following disadvantages: Energy loss: Eddy currents create circular currents in conductors, which generate heat as they flow continuously in conductors. Since the generation of eddy currents is caused by changes in the magnetic field, in equipment such as transformers and motors.

Poor power quality can severely impact the performance of transformer equipment, leading to a variety of negative outcomes. These consequences not only affect the operational efficiency of the equipment but also pose significant economic concerns. One of the primary damages caused by poor PQ is the deterioration of the transformer’s health. Poor PQ, characterized by factors like voltage sags, swells, harmonics, and transients, can cause excessive heating in transformers. This undue heat can degrade the insulation material used in transformers, subsequently reducing their lifespan and potentially leading to catastrophic failures. Therefore, poor power quality can lead to considerable damage to transformer equipment, resulting in economic losses, reduced energy efficiency, and decreased productivity. Therefore, maintaining high power quality is crucial for the optimal performance of transformer equipment and overall operational efficiency.

With the development of the times, people’s demand for power supply and the reliability of power supply are increasingly high, so the smart grid has emerged accordingly.In the power system, the core and hub of the substation is the transformer.The function of the transformer is mainly to distribute and convert electric energy. The normal operation of the transformer directly affects the normal function of the substation.The intelligent operation of the transformer mainly involves the protection and status monitoring of the transformer, so as to achieve real-time monitoring of the transformer and ultimately ensure the safety and reliability of power supply.

Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
