Feeder Protection

Definition: Feeder protection is defined as the protection of the feeder from the fault so that the power grid continue supply the energy. The feeder injects the electrical energy from the substation to the load end. So it is essential to protect the feeder from the various type of fault. The main requirement of the …

Electrical Drive

Definition: The system which is used for controlling the motion of an electrical machine, such type of system is called an electrical drive. In other words, the drive which uses the electric motor is called electrical drive. The electrical drive uses any of the prime movers like diesel or a petrol engine, gas or steam …

Proximity Effect

Definition: When the conductors carry the high alternating voltage then the currents are non-uniformly distributed on the cross-section area of the conductor. This effect is called proximity effect. The proximity effect results in the increment of the apparent resistance of the conductor due to the presence of the other conductors carrying current in its vicinity. …

Sag Template

Definition: The sag template is used for allocating the position and height of the supports correctly on the profile.The sag template decided the limitations of vertical and wind load. It also limits the minimum clearance angle between the sag and the ground for safety purpose. The sag template is usually made up of transparent celluloid, perplex, …

Cable Capacitance

Definition: Cable capacitance is defined as the measurement of the electrical charges stored  within it. The capacitor in the cable is constructed by two conductive material which is separated by an insulator or dielectric. The capacitance of the cable determines the charging current, charging KVA, and the dielectric loss. The capacitance of a cable transmission line …

Electrical Energy

Definition: The energy which is caused by the movement of the electrons from one place to another such type of energy is called electrical energy. In other words, electrical energy is the work done by the moving streams of the electrons or charges. Electrical energy is the form of kinetic energy because it produces by …

Insulation Co-ordination

Definition: Insulation coordination is the process of knowing the insulation levels of the power system components. In other words, it is the process of determining the insulation strength of the equipment. The internal and external insulation of the electrical equipment is exposed to continuous normal voltage and temporary abnormal voltage. The equipment insulation is designed …

Electrical Conductor

Definition: The conductor is the type of metal which allows the electrical current to flow through it. The electrical conductor is generally made up of metals like copper, aluminium and their alloys. In an electrical conductor, the electrical charges moves from atom to atom when the potential difference is applied across them. The electrical conductors are …
