In April 2013, some topics remained without answer. Maybe you could help the members to solve their problem.

Don't forget: it takes 5 minutes to do it and the person asking may become the one to answer YOUR questions in the future!

1. How to design and implement a simulator of a protective grounding system?

2. Reduce losses in hvdc with using microcontroller for transmission and distribution sector

3. A practical problem in three phase Induction Motor

4. DC motor transients simulation in MATLAB

5. Can a relay work with low voltage and current?

Thanks in advance for your active contribution to our community.

    Generator Ratings (back to basics)

    When an Electrical Engineer is in field dealing with generators, then it’s very important for him to know the rating of under process generator otherwise he may cause a great loss. Let’s go back to basics...

    VAR & Its Applications

    The abbreviation VAR stands for Volt Ampere Reactive or as commonly referred to as the reactive power. The purpose of this device is to provide a rapid reactive power in the case of high voltage electrical transmission networks. This article is a holistic view of the static VAR design along with its pros and cons. A comparison is also drawn with the mechanical model on the account of functionality and usage.

    Circuit Breaker Switching

    Power failure or a short circuit in the system can occur at any time. It may not even give us the chance to turn off the appliances connected. This may sometimes lead to heavy loss because the faulty current passing through the electrical network system may damage the electrical equipment. So it is important to get the current out of the system as soon as possible. For this, several switching systems are to be implied so that not only the current causing disturbance is removed from the network but also that the appliances get the current so as to cause minimal loss.

    This article contains information on circuit breaker switching only, but a detailed topic around arc modeling will be soon published as a second part. Till then, give your impression about this first part.
