You might have noticed huge towers supporting the high voltage transmission lines in your locality. These high voltage lines transmit electric power generated at power stations which are situated at…
Short Circuit A short circuit occurs when two or more current carrying conductors of different phases or different voltage levels or different terminal (in DC circuits) come in contact with…
In AC power system, power factor is a very important parameter that defines how efficiently electric power is being utilized by the load. It is a rational number between -1 and 1 but has no unit. The power factor of a system depends on the type of load present, whether resistive, inductive or capacitive. The inductive and capacitive load has a negative impact on the power factor of the system. Poor power factor results in an increase in current drained by the load.
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…
What is short circuit?
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.
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…)
