Why Should you Learn ETAP?

ETAP stands for Electrical Transient Analyzer Program. It is a powerful tool do modeling, simulation and analysis of power system. Before we drive deep into the scope of ETAP in industries for an Electrical Engineering graduate, it is imperative to know what exactly is ETAP? So, we shall first have a broad view of this … Read more

Why does Megger have a DC Generator?

Megger is a brand name of Insulation Tester. Due to the popularity of this brand, we often use this term to mean Insulation Tester and Megger value to mean Insulation Resistance value. Today, there are various other make of Insulation Testers available and therefore it is better to call it Insulation Tester instead of Megger. … Read more

Sign Convention in Electrical Circuits

Sign convention is the generalized way to solve and analyze the electrical circuits. It defines the positive or negative sign to be taken for various electrical parameters viz. current, voltage, power etc. Sign convention brings uniformity in the value of electrical parameters so that anyone can understand the analysis of circuits. Our Universe is diverse … Read more

Calculation of Current through a Diode

Current through an Ideal Diode: The diode equation gives an expression for the current through a diode as a function of voltage. The Ideal Diode Law, expressed as shown below   Where, I = the net current flowing through the diode I0 = Reverse Saturation Current V = applied voltage across the terminals of the … Read more

Step Potential and Touch Potential – Must Read

Step potential is the voltage between the feet i.e. one step of a person standing near an energized grounded object. Touch potential is the touch voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the object and a point … Read more

Why Sinusoidal Voltage and Current used, why not Square or Other?

In Electrical Engineering, every time our aim is to get the perfect Sinusoidal voltage or current without having any harmonics. But the question arises why do we select Sinusoidal waveform why not other waveform for voltage and current? The following reasons favor the use of sinusoidal wave: For Sinusoidal wave, hysteresis and eddy current losses … Read more

Expectations of Industries from an Engineer

In today’s scenario, Industries expects something ahead of CGPA in this competitive world from an Engineer. 20-33% out of the 1.5 million engineering graduates passing out every year run the risk of not getting a job at all, points out EconomicTimes. This is because they lack some of the skills which are expected from the industries, … Read more
