What are the different faults occurring in the overhead transmission lines?
1. Single line to ground fault.
2. Line to line fault.
3. Double line to ground fault.
4. Line to line to line fault (Three phases are short-circuited)
5. Three line to ground fault. (more…)
On which part of the power system the occurrence of failure / abnormal condition is more? The probability of occurrence of failure / abnormal condition is more in the on…
A short circuit is a situation in which two or more different lines (having different voltage levels/ different phase/ different terminals) come in contact and finally leads to the flow…
Buchholz relays are generally used to sense abnormal conditions occurring inside a transformer. It is a type of oil and gas actuated protection relay. It can be seen in all…
Conventional energy is obtained from the conventional energy resources such as coal, diesel, gas and nucleus. These are non-renewable resources and may exhaust in few decades if consumed at the current rate. The burning of fossil fuels produces harmful gases such as nitrous oxide, carbon monoxide, sulphur-di-oxide etc and pollutes the environment. The comparison of various factors of power production from the conventional resources is listed below. (more…)
Ballast is used to supply a high starting voltage. The ballast also regulates the lamp starting current and lamp operating current. (more…)
