In AC power systems, both at the home and grid levels, bridging between different wires in the system leads to different types of electrical faults. One interesting type of electrical fault in a 3-phase system is an LLLG fault (line-line-line-ground). This type of fault is among the le...
AC drive is a device used to control the speed of an electric motor such as a three-phase induction motor by changing the frequency of the electrical supply to the motor. AC drive is also calledVariable Frequency Drive(VFD) or Variable Speed Drive (VSD). DC Motor drives It is basically ...
Just know that in the world of electronics, an electric current of -20 mA flowing from minus to plus is the exact same thing as a current of +20 mA flowing from plus to minus. Questions After reading this, is it clear to you what electric current is? Do you have any questions? Let...
What is an Electric Vehicle Controller? Increasing concerns regarding climate change have encouraged the adoption of electric vehicles. Electric vehicles offer low carbon emissions, a minimum dependency on non-renewable resources, and promote innovation in the automotive sector. Hence, the need to learn...
It is an international standard used for vehicle diagnostics, implemented by the United Nations as part of the Global Technical Regulations (GTR) mandate, which includes vehicle data monitoring such as emissions output and engine fault codes. Advantages of WWH-OBD Here’s a look at the benefits ...
What is an Inductor? An inductor (also known as an electrical inductor) is defined as a two-terminal passive electrical element that stores energy in the form of a magnetic field when electric current flows through it. It is also called a coil, chokes, or reactor. An inductor is simply ...
A turbocharger is a critical component highly customized for the engine. It uses an engine’s exhaust gas to drive the turbine wheel up to 350,000 RPM. The turbine wheel then drives the compressor wheel through a shaft. The compressor wheel provides compressed air to the engine, and thi...
Elaborating on this, the working principle of a circuit breaker is based on the interruption of the electric current in an electrical circuit. A circuit breaker mainly consists of fixed contacts and moving contacts. These two contacts are physically connected to each other in the normal “ON” ...
In automatic transmission vehicles, the car goes into limp mode if there is any fault with the transmission. Limp mode is also activated when the transmission control unit determines that the vehicle’s clutch is broken, damaged, or defective. ...
The inspector will identify the kind of wiring the home has, test all the outlets, and make sure there are functional ground fault circuit interrupters (which can protect you from electrocution, electric shock, and electrical burns) installed in areas like the bathrooms, kitchen, garage, and ou...
