Tricky but Easy Electrical Engineering!
This is a famous question which most of the people ask to an Electrical Engineer that “Suppose we are setting up a power plant so shall we use HVDC or HVAC Transmission?” In this post I am going to answer this question with examples which will help to clear the concept. We have already seen … Read more
In AC circuit breakers/ arc extinction is achieved at the natural current zero of the AC waveform used. But in DC circuit breakers / natural zero of voltage and current is not available as both are continuously available. Thus for extinction of an arc, artificial current zero is required to be introduced. Such an artificial … Read more
A scheme diagram of HVDC Transmission is shown below for ease in understanding the advantages and disadvantages. Advantages of HVDC: There is a list of advantages of High Voltage DC Power Transmission, HVDC when compared with High Voltage AC Power Transmission, HVAC. They are listed below with detail while comparing with HVAC. Line … Read more
As we know that High voltage AC is used to transmit the electrical power for reducing the power transmission losses and because of the flexibility of AC System. In a transmission system different Grids are interconnected but some time it may happen that one or more Grid or Power System may not be in synchronization … Read more
