AC induction motors are widely used in industrial and commercial applications due to their robustness, reliability, and efficiency. However, it’s important to properly size the electrical circuit and components for a motor to ensure it operates safely and efficiently. One important factor to consider is the full load current of the motor, which is the […]
An IDMT (Inverse Definite Minimum Time) relay is a type of protective relay that is used to provide overcurrent protection for electrical systems. IDMT relays are commonly used in low-voltage and medium-voltage electrical systems to protect against overcurrents caused by fault conditions such as short circuits. IDMT relays work by monitoring the current flowing through
During electrical power calculation, typically we use the normal calculator, in which sometimes we make mistakes during ac power calculations. Ac power consists of a power factor which we have to take into consideration. Again for three phase we have consider root 3 facor. This simple calculator will reduce the possibility of making an error
The power factor is a concept that is needed to be very clearly understood by electrical engineers. It is studied in the first or second year of the engineering courses when the students are not fully ready to grasp all the bits and pieces of this concept. Here I tried to write down the necessary
