Hi my fellows electrical engineers, it’s Steven Mill and today I want to deal with safety basics. So here is an article about Safety before, during and after power outage. Let me know what you think about it!

The electric power supplied to homes, factories, public places and other installations have the potential to harm the users. Even the domestic installation, which is one of the smallest, has enough current to cause death by electrocution. Other than the direct harm resulting from touching the live conductors, there are other indirect dangers such as fire hazards or accidents by moving electromechanical parts.

How to calculate the load? (back to basics)

New back to basics article from one of our kind member of the community. What do you think about it?

One of the important things in the design of an electrical installation either on middle or low voltage is to choose the right conductor for the given consumers. Therefore, in this article I will examine how to calculate the load and what type of conductor you can use in the different situations.

To figure out the load we need to calculate the current that flows through the conductor. We can calculate it very easily via the well-known formula:

P=U*I*cosϕ, where:

P – power

U – voltage of the network

I – current

cosϕ – power factor

Let us assume that cosϕ=1, in that way the formula will become P=U*I, and from here we can deduce the formula for the current


Year 2050 in terms of Electrical Power (scenario)

It was not long ago when the Edison Electric Illuminating company supplied 600kW of energy from 6-dynamos to 85 customers. Just in a gap of 125 years the world has changed so much that 20,000 TWh of electric power is generated and supplied to 7 billion customers all over the world, a fact that all Electrical engineers can be proud of.

With the world seeking a solution to meet the existing power crisis, this article takes you through a long-term vision, “Electricity scenario in the year 2050”. This is just a statement ensuring we work hard to give the future generation a power crisis free world to work with.

Numerical values expected in 2050

The demand for electricity is definitely going to increase by the year 2050 as the use of fossil fuel must be substituted and as of now the only available substitute is electric power.

Let us see how much energy we need by the year 2050:
