Transformer Differential Protection

What is Differential Protection? Differential Protection is based on the fact that any fault within electrical equipment will result into the difference in current entering it and the current leaving it. Thus by comparing the two currents either in magnitude or in phase or both...

What is Tunnel Diode?

A tunnel diode is a diode that exhibits a negative differential impedance region in its I-V characteristic due to quantum tunneling effects. That is, a -sloped region as shown by red colored region in the figure below. It’s a diode, a kind of semiconductor device...

Concept of Infinite Bus

For understanding the concept of Infinite Bus, we will take some examples. Suppose we take an isolated synchronous generator of capacity 100 kW and supplying a load of, say 50 kW, at 50 Hz and rated voltage, say 400 V. Now if we add a...
