RCCB stands for Residual current circuit breakers and MCB stands for Miniature circuit breakers. Both of them are basic circuit protection devices found in the distribution boards of every house and commercial lighting power distribution boards. Here are the differences between MCB and RCCB. RCCB – Residual Current Circuit Breakers Residual current circuit breakers are … Read more
In the world of industrial automation, Programmable logic controllers (PLC) and Distributed Control Systems (DCS) are used to control or automate a process or a machine. They monitor the field signals and operator inputs and make decisions based on how they are programmed. Here you can understand the difference between PLC and DCS. What is … Read more
Electromagnetic induction occurs whenever there is a relative motion between a magnetic field and a coil. The electromagnetic force acts on the charged particles inside the coil, forcing them in one direction along the coil. If ends of the coil are closed, it results in a current flow. This current is known as induced current. … Read more
The terms, motor rated current, full load current and nominal current, are very likely to confuse electrical engineers. Even though these terms are quite similar, there are slightly different from each other. Here is the clear definition of each one of them. Definitions Motor rated current The current drawn by a motor at its full … Read more
An electric motor is an energy transformation machinery. It transforms electrical energy into mechanical energy. In other consumes electrical energy and delivers mechanical energy in the form of rotations. For example, an electric fan consists of a motor that draws electric energy from the mains and delivers kinetic energy (mechanical energy) in the form of … Read more
The bipolar junction transistors exist as NPN and PNP types. This article intents to help you understand the difference between these two types and how to use them in a circuit. Also, this will be helpful to automation engineers and instrumentation engineers in understanding 3 wire sensor connections. Transistors are made by combining two types … Read more
Circuit breakers are employed to automatically switch off a circuit or a load whenever any abnormalities in current flow are detected. This functionality of the circuit breakers is known as ‘Trip’. By doing so, circuit breakers are preventing fire or other damages caused to the circuit. Here are the major reasons behind your circuit breaker … Read more
A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this current is used to create flux in the transformer core. This current is known as magnetization current. Definition of magnetization current Magnetization current can be … Read more
kW and kVA are units of power. kW stands for kilo-watts and kVA stands for kilo-volts ampere. Let’s see what is the difference between kW and kVA and how to calculate each one of them. The key differences between kW and kVA kW – Kilowatts kVA – Kilo-volt amperes It is the unit of electric … Read more
kVA stands for kilo volt-amperes. It is basically the unit of apparent power and is the product of RMS values of voltage and current. One kVA is 1000 volt – amperes Apparent power Apparent power is the actual amount of power drawn from the source. It includes both true power and reactive power. Apparent power … Read more
