One of the major difference between the diode and the transistor is that the diode converts the alternating current into direct current while the transistor transfers the input signals from the low resistance circuit to high resistance circuit. The other differences between them are explained below in the tabulated form. The diode is also known …
The classification of the transmission lines depends on its voltage and the length of the conductor. The transmission line is the medium of transferring the power from the generating station to the load centre. It is mainly classified into two types. They are the AC Transmission Line Short-Transmission Line Medium Transmission Line Pi Model of …
Definition: The voltage or line regulation is defined as the variation in the voltage at the receiving end of the line when the full load at a given power factor is removed and the voltage at the sending end being kept constant. In other words, it is defined as the percentage variation in voltage at …
The UPS and inverter both provides the backup supply to the electrical system. One of the major difference between the UPS and inverter is that the switching of UPS from the main supply to the battery is very immediate whereas in inverter the switching from mains supply to battery takes times. The UPS and the …
Definition: The device which takes electrical energy is known as the electric load. In other words, the electrical load is a device that consumes electrical energy in the form of the current and transforms it into other forms like heat, light, work, etc. The electrical load may be resistive, inductive, capacitive or some combination between …
One of the major difference between the short circuit and the overload is that the short circuit occurs because of the fault between the lines or line-to-earth whereas the overload means the equipment draw the excess of current from the supply. The other differences between them are explained below in the comparison chart. The term …
The fault in the power system is defined as the defect in the power system due to which the current is distracted from the intended path. The fault creates the abnormal condition which reduces the insulation strength between the conductors. The reduction in insulation causes excessive damage to the system. The fault in the power system is …
Definition: The system which has three phases, i.e., the current will pass through the three wires, and there will be one neutral wire for passing the fault current to the earth is known as the three phase system. In other words, the system which uses three wires for generation, transmission and distribution is known as …
Definition: The system without neutral grounding is known as the ungrounded system, or in other words, in the ungrounded system, none of their conductors is connected to the ground. The main feature of the ungrounded system is its ability to remove the earth faults without interruption. But the self-cleaning process of the ungrounded system become …
Definition: The resistance offered by the earth electrode to the flow of current into the ground is known as the earth resistance or resistance to earth. The earth resistance mainly implies the resistance between the electrode and the point of zero potential. Numerically, it is equal to the ratio of the potential of the earth …
