## Difference between Capacitive Voltage Transformer and Potential Transformer

A PT, Potential Transformer, can be thought of as a pure transformer with primary and secondary windings; PT’s are sometimes referred to as magnetic transformers due to the fact that their mode of operation is purely magnetic. It is used to step-down the input voltage...

## Capacitive Voltage Transformers (CVT)

The application for capacitor voltage transformers, CVTs, is the same as for Inductive Voltage Transformers. The main function of a Capacitive Voltage Transformer is as follows: To transform currents or voltages from a usually high value to a value easy to handle for relays and...

## AC or DC Power – Which one More Dangerous?

Alternating Current (AC) and Direct Current (DC) have slightly different effects on the human body, but both are dangerous above a certain voltage. The effect on a particular person is very difficult to predict as it depends upon a large number of factors like amount...

## Basics of Stepper Motor

A Stepper Motor is a special form of AC Motor. The input of this motor is in the form of electric pulse. For each input pulse,motor shaft turns through a specified degree, called Step. The Step size may vary from 0.72° to 90°. This means...

## Difference between Earthing, Grounding and Neutral

Earthing means connecting the dead part, it means the part which does not carries current under normal condition to the earth. For example electrical equipment’s frames, enclosures, supports etc. While Grounding means connecting the live part (it means the part which carries current under normal...

## BDV Test in Transformer

BDV test means Breakdown Voltage Test. It is done for checking the dielectric strength of the oil of the Transformer. Dielectric strength means the maximum capacity to withstand voltage of insulating oil. This test shows the dielectric strength of Transformer oil. In transformer oil has...

## Differences between a Phasor and a Vector

If someone ask you whether current and voltage are vector or scalar quantity the obviously you will answer that they are scalar quantity. Next, the question arises if current and voltage are scalar quantity then why do we represent then in form of vector which...

## Difference between Generator, Inverter and UPS

Generator: A generator is a machine that converts mechanical energy into electricity. A generator generally requires fuels like kerosene, petrol, diesel, etc. Fuel is used as the source of mechanical energy. A generator is used mostly when a lot of power is required. Generally small...
