An electric motor is a machine that uses the concept of conversion of energy and consequently converts electric to mechanical energy. The main parts that help propel the process are the rotor, stator, windings, air gap and commutator. The approximate efficiency of an electric motor is 70%-85% (extra energy is taken by the sound and [...]
Each process of construction is directly or indirectly related to the other, so having a bit of knowledge about each one of these is imperative even if you specialize in only one. Phases of Electrical Construction From a contractor’s perspective, the construction of a house can be divided into two main phases: wet and dry. [...]
A burnout, in electrical terms, is a drop in voltage across an electricity supply system. It can be spontaneous (unintentional) caused by disturbances in the grid, or intentionally caused during emergencies when the load needs to be reduced in order to prevent blackouts. The lower voltage causes lights to dim, leading to the name “burn [...]
One of the biggest challenges faced by electrical engineers, while designing and installing circuitry, is ensuring that electrical fittings can accommodate different plugs. The terms ‘electrical outlet’ and ‘electrical receptor’ are interchangeable, and they do a lot more than just provide electrical connectors for devices to plug into. What Does Electrical Receptacle Configuration Mean? Electrical [...]
Mechanical lugs are connectors that are used to connect cables together, and they form an important part of a home electrical system. Mechanical lugs are normally made from one of two metals – copper or aluminum. As far as functionality goes, they both serve similar purposes, but the differences become obvious when you look at [...]
There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion. Forget colleges and engineering schools, most high school students [...]
Limit switches, as the name suggests, are precision switches that are designed to work as limiting devices. The switch is typically snap-action and designed to sense the presence, absence, or be triggered by an excess or lack of physical contact at the position where it is installed. The flexibility and adaptability of limit switches to [...]
Electricity is like a kitchen knife. If you use it wisely, it can cut food and prepare delicacies. If you use it unwisely, it can end up cutting your finger. Electricity flows through anything that is a “conductor.” Interestingly, humans are very good conductors of electricity! Why are Cables Insulated? Since electricity is a form [...]
Oil and natural gas resources are highly in-demand for the fuel and energy sectors, and this demand will continue to grow. Companies working in these sectors are often hard-pressed to put effective electrical systems in place that can handle the energy requirements without compromising on safety and reliability. The good news is that modern electrical [...]
A switch, at its core, is something that will allow the current to flow or stop it from flowing. You use switches throughout your day and almost every aspect of your life for lights, fans, appliances, elevators, etc. Here we’ll look at different types of electrical switches, the differences between them, as well as their [...]
