Tricky but Easy Electrical Engineering!
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
Integral Cycle Control is a strategy to control the output voltage of AC voltage controller. In this strategy, load is connected to the source for an integral number of cycle of input supply and then disconnected by switching off the supply for a further number of integral cycles. This strategy is also known as on-off … Read more
Single Phase AC Voltage Controller is a device which converts fixed single phase alternating voltage directly to a variable alternating voltage without a change in frequency. The input and output of the device is single phase. There are two types of single phase AC Voltage Controller: Single phase Half Wave and Single phase Full Wave. … Read more
Definition: AC Voltage Controller is a thyristor based device which converts fixed alternating voltage directly to variable alternating voltage without a change in frequency. AC Voltage Controller is a phase-controlled device and hence no force commutation circuitry is required. Natural or line commutation is used. Phase control means that the phase relationship between the start … Read more
Step-down cycloconverter is a device which steps down the fixed frequency power supply input into some lower frequency. It is a frequency changer. If fs & fo are the supply and output frequency, then fo < fs for this cycloconverter. The most important feature of step-down cycloconverter is that it does not require force commutation. … Read more
This article explains the Octal Number System. Method to convert decimal to octal and octal to decimal number has also been explained with example. What is Octal Number System? A number system which uses only eight digits viz. 0, 1, 2, 3, 4, 5, 6 to 7 is called Octal Number System. The base or … Read more
To convert binary into decimal, each bit of the binary number is first multiplied with 2(n-1) where n is the position of the particular bit when counted from Least Significant Bit (LSB). The result so obtained are then added to get the equivalent decimal number. We will discuss the entire process / method of converting … Read more
An easy method of converting a decimal number into binary number is by dividing the decimal number by 2 progressively, until the quotient of zero is obtained. The binary number is obtained by taking the remainder after each division in the reverse order. This method to convert decimal number into binary number is popularly known … Read more
A single phase to single phase cycloconverter is a type of cycloconverter whose input & output are single phase AC. The basic function remains the same i.e. frequency changing. A single phase to single phase cycloconverter may either be mid-point type or bridge type step-up or step-down cycloconverter. In this article, we will understand the … Read more
Step-up cycloconverter is a single phase to single phase device which converts input AC power at one frequency to output power at a different frequency. The output frequency is more than the input frequency for this cycloconverter. Single phase to single phase means that both the input power and output power are single phase. This … Read more
