Definition of instrument transformers Instrument transformers are current and voltage transformation devices that are used to step down the transmission and distribution line voltages and currents to levels that can…
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 an AC power system, the power factor is a very important parameter that defines how efficiently electrical power is being utilized by the load. It is a rational number…
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. (more…)

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…
