Anyone who uses electricity and have heard of terms: single-phase and three Phase, maybe trying to understand the difference between them. This article narrates the differences between a single-phase power…
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 each…
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.
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…
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.
