What will happen if a DC voltage is applied to a transformer coil?
This is a quite common question asked by many. In fact, it is necessary to know why we don’t apply DC voltage to a transformer coil. You may come across the same question during interviews too. This article can help you clear your query. Well! Here is the answer: Before explaining what will happen if a … Read more
Difference between MCCB and RCCB
Difference between MCCB and RCCB MCCBs and RCCBs are circuit protection devices with two different application. When the former protect against overload and short circuit, the later protects against Residual currents and electric shock. MCCB- Molded Case Circuit Breakers Moulded Case Circuit Breakers protect against overcurrent and short-circuits only unless otherwise, they have inbuilt residual protection. MCCBs trip as … Read more
Difference between MCB and MCCB
MCBs and MCCBs have commonly used circuit protection devices. These devices provide protection against overcurrent and short circuits. In this article, let us discuss the difference between MCB and MCCB. Overview of MCB: These are thermal / thermo-magnetic devices Provides protection against overcurrents and short circuits. Available up to 100A and have a maximum short … Read more
Difference between contactor and relay
Contactors and relays are electrically operated switches used for the control and switching of loads. The difference between them primarily lies in the load current that they can handle, where they are used, and how they are used in a circuit. This article can give you a clear picture of the difference between contactor and … Read more
Difference between soft starters and VFDs
The most important difference between soft starters and VFDs is the role they play in motor control. Even though they have a similar principle of operation, they are different. This article will help you understand the difference between soft starters and VFDs. Why use VFDs and soft starters? When started by a direct-on-line starter, a … Read more
What is Comb Busbar?
Comb busbar is one of the most basic switch gear instruments. The main purpose of a comb busbar is to distribute power to switch gear components such as MCBs. There are two types of comp busbar viz, single phase comp busbar and three phase comb busbar. It can be found in small distribution boards that you … Read more
What is an Electric Circuit?
Two or more circuit components such as power source, resistors, inductors and capacitors when interconnected, it forms an electric circuit.
Difference between volts and watts
Volts and watts are two of the most common and key terms in the field of Electrical and Electronics Engineering. Most of the times these terms confuse the newbie or those who have just started learning Electrical sciences. Even though these two terms sounds alike, they are different from each other. Here is a simple … Read more
