Ammeter selector switch is basically a normal three position switch. In large Electrical distribution panels, an ammeter is used to monitor the current through each line.
Why the power system is divided into several protections zones?
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.
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 the power line. The reason is nothing other than its length and operating conditions. It is highly affected by the weather conditions and other atmospheric … Read more
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 of large short circuit currents that may damage the equipment or the system. In a three-phase system, a occurs when two or more phases come … Read more
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 … Read more
Fuel cells cleanly and efficiently convert chemical energy from hydrogen-rich fuels into electrical power and usable high-quality heat in an electrochemical process that is virtually absent of pollutants. What are fuel cells? Fuel cells are non-polluting energy resources. It cleanly and efficiently converts chemical energy from hydrogen-rich fuels into electrical power. Each fuel cell consists … Read more
