Differential busbar protection is the most common and reliable scheme for the bus bar protection. Earlier there was no other option to use only conventional over current relays for busbar protection. But it is desirable that fault in any feeder or transformer connected to the busbar system should not disturb overall busbar system. Due to… Read More »
DC motor runs on direct or dc current. On this page we shall understand the function of each component of the motor. In general there are two major parts of any motor i.e. stationary part and moving part. The stationary part is mainly the outer part that houses the field windings and receives the supply also… Read More »
Thermal power generation is one of the method that costs high as compared to hydro and other renewable energy methods. Since the fuel burning is involved the wastage of fuel is also high if not properly burned and result is the higher cost of thermal power. The considerable increase of the demand of electricity throughout… Read More »
To better understand the servo motor let us first see what is the meaning of term “servo”. The term servo is applicable for any system that uses a feedback mechanism in order to control the required situation. The feedback can be in the form of signals from sensors or limit switches or number of revolutions,… Read More »
What is an ammeter? Ammeter or ampere meter is an electrical measuring device, which as seen from its nomenclature is useful for the measurement of the ampere i.e. to measure electric current through the circuit. The normal symbol of ampere meter is capital A mentioned inside a circle. This is the way ammeter is symbolized… Read More »
As a new electrical student or a common man this questions comes in mind that why we prefer 3 phase power system. In recent years 3 phase electric wiring has become common and mostly used worldwide for power generation, power transmission, distribution and three phase engines or motors. A single-phase electric power supply is the… Read More »
