## Transmission Line Parameter Calculation

When doing the load flow study in the Simulink environment, we need to put the transmission line parameters in the Simulink block. In the question, typically, the parameters are given as per unit values. But when we put the values into the Simulink block, we need to put the actual resistance, inductance, and capacitance value …

## IDMT Relay Tripping Time Calculator

Inverse definite minimum time (IDMT) relay is a form of overcurrent relay that operates in inverse time fashion with the current in the protection system. Basically, with the change in the peak value of the current, the time required for the relay to perform is decreased. The measurement of operating time starts immediately when the …

## Amps to Kilowatts Converter

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 …

## Power Factor Correction: Methods Explained

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 …
