 The use of electronics in today’s technology has increased in controlling various actuating systems such as hydraulic and pneumatic systems in process industries and has naturally led to greater in interest in servo and proportional valves. Both these servo valves and servo proportional valves are electrohydraulic and electro-pneumatic continuously acting type valve that transforms a varying analog or digital input signal into a step less output signal. This signal may be a flow or pressure signal. These Servo valves and Servo-Proportional Valves are electrohydraulic valves, These are continuously acting valves that transform a changing analog or digital input signal into a step-less hydraulic output (flow or pressure). The term servo valve defines a valve design that consists of a bushing spool assembly Indicated by high-precision metering edges. Basically, the name servo valve relates to the term servomechanism, which means that the valve is constantly monitored to control its m...

 Fiber optic cables and coaxial cables are used in various applications. But many of us are still not having proper knowledge about fiber optic cable and coaxial cable. So, today in this article we will discuss the difference between fiber optic cable and coaxial cable. Comparison of Fiber Optic and Coaxial Cables The following are the main comparison between fiber optic and coaxial cables. Physical Construction Material of Construction Transmission Method Bandwidth Transmission Speed Efficiency Diameter Weight Installation Complexity Cost Uses Physical Construction Fiber optic cable is made of the core which is a fiber core. Outside the fiber core, a cladding is present. Cladding is protected by a coating and a strength membrane. This whole assembly is protected by an outer jacket. Coaxial Cable is made up of conductors which are protected by insulators and sheath/shield and outer cover. Material of Construction Fiber optic cable is made up of plastics and glass. While coaxial cab...

 Whenever you pass around a transformer, you must have heard a strange sound of humming surrounding it. This is mostly heard in large transformers. This sounds weird but it is true; because everyone wonders why if there is no moving part in it, then why the sound is produced. In this post, we will learn why a humming sound is produced in a transformer because it will then help the engineers to design the transformer properly. Transformer Humming Sound A transformer works on converting voltage either in step-up or step-down mode. It has two basic windings – primary and secondary. The windings are wound on a laminated magnetic core sheet. There are multiple such sheets in a transformer housing. These cores are multiple in number to reduce Eddy current losses. When current flows through windings, a magnetic field is generated around the cores. It will then flow fully around the cores. This means that the laminated sheets are now turning into a magnet when electric current flows throug...

 In this article, you will learn the basics of the managed switch and unmanaged switch in networking. The network Switch is one of the most important parts of any network. All the communications going on a network are only possible because of a network switch. The network switch receives data from one port and sends the data to the other port or the correct location. Because of this functionality, the network switch is also called the brain of any network. Because the network switch manages the data communication between all the devices on the network. Any Network Switch can be classified on the basis of the number of ports. The most common type of network switch is 24-port and 48-port network switches in industrial applications. But one of the main parameters which differentiate network switches is whether the switch is managed network switch or an unmanaged network switch. What is the difference between a managed network switch and an unmanaged network switch? One of the most bas...

 Electricity is a very basic need in our day-to-day life. In today’s world, it is almost impossible to survive without electricity; as almost all devices from a small fan to a PC to an AC work with electricity. So, even a small amount of interruption for some period of time can hamper our lives. We get power supply from the primary source, which is directly from electrical power distribution grids. This is called a mains power supply. But, for backup purposes, in case of mains power failure, other secondary sources are used like diesel generators, UPS, or inverters. Related to both of these, we will learn about an important device that is used for power supplies – auto changeover switch. In this post, we will learn the concept of an auto changeover switch. What is an Auto Changeover Switch? Suppose you have two sources of electricity – primary and secondary. Earlier, when the mains power supply went off, the operator used to go and manually turn on the secondary source power supply...

 In this post, we will learn the reason behind the use of a capacitor in a fan. Ceiling fan or table fan is one of the most commonly used devices everywhere. It is almost impossible to survive without a fan in an area where there is no natural ventilation or air conditioning. So, it is important to understand the importance of a fan. You must have heard that a capacitor is one of the most essential used parts of a fan. But, do you know why such a small part can affect the working of the fan? Why is Capacitor Used in a Fan? Let us first start from the basics. A fan works on a single-phase motor. You will not have heard of a fan working on three phases. So, a fan always requires a single-phase AC supply. Now, if you see the working of a motor, you will be knowing that it is a device that converts electrical energy into mechanical energy. This is due to Faraday’s law of electromagnetic induction. If electrical energy is passed through a magnet, an electromagnetic field is generated wh...

 Electricity is one of the basic needs of human beings in today’s life. Everything from our life is utilized by electrical energy that may be from health to fun and from transportation to traffic. As a result, social and economic influences are inevitable in an interrupted situation.  In normal operating conditions energy production systems enable electricity to reach consumers easily. Energy interruptions can occur due to disturbing currents.  When the power system is defined as a power grid collapse, which is partially or completely out of order, it is the most negative situation for power system operators. Blackout of Electrical Power Grid The electric power grid serves as a bridge between energy production plants and consumers. Energy supply and demand balance problems may occur at any time. These problems cause the voltage and frequency of the power grid to increase or decrease. Through these distortions, the power system is causing the power generation plants to be ...
