Insulation resistance is a measure of how effectively an electrical insulating material prevents the flow of current through it. It is crucial in electrical systems to ensure safety and proper operation. It should be checked often so that cases of weak insulation can be early detected and weaker …
Transformer A transformer is a static piece of apparatus by means of which electric power is transferred from one circuit to another without a change in frequency. It can raise or lower the voltages with a corresponding decrease or increase in current. It is accomplished by Faraday’s law …
Electrical Faults are basically abnormalities of parameters either voltage or current or both in a stable system. Faults are generally caused by equipment failure, human error, and environmental conditions. Electrical faults can cause significant economic damage and have the potential to cause fire hazards risking human life. CLASSIFICATION …
OVER VOLTAGE IN ELECTRICAL POWER SYSTEM Increase in voltage for the very short time in power system is called as the over voltage. It is also known as the voltage surge or voltage transients. The voltage stress caused by over voltage can damage the lines and equipment’s connected …
BASIC INSULATION LEVEL (BIL) Basic insulation level, BIL refers to the voltage level that a system of insulation can withstand without breaking down or experiencing a dielectric failure. Dielectric failure is the sudden breakdown of insulation properties that occurs at a certain level of voltage at which the …
Different Bus bar arrangements/schemes and their advantages The bus bar is a common conductor/group of conductors where all incoming and outgoing feeders connect. It collects the incoming electrical power and distributes it to the outgoing circuits. We can say it works on Kirchhoff’s current law. The bus bar …
In the realm of modern electricity distribution, Gas Insulated Switchgear (GIS) Substations representa pivotal advancement. These sophisticated systems play a crucial role by enhancing the efficiency, reliability, and safety of power transmission across various applications. A gas-insulated switchgear substation is a compact, metal-enclosed structure that houses high-voltage …
Air insulated Switchgear or AIS Substation is a type of substation where all electrical switchgear and other high-voltage equipment’s insulation to earth and between phase conductors are mainly provided by air at atmospheric pressure and where some live parts are not enclosed. ADVANTAGES Cost-Effectiveness of AIS Lower initial investment …
Substations are among the components of an electrical power system that plays a very important role in the transmission and distribution of electricity from generating power plants or sources, to the consumer’s load. It serves as an intermediary point between the source and load distribution networks. The main …
The Backbone of Power: Transmission lines are among the overlooked heroes of modern civilization, as they facilitate the flow of power from generating plants to our homes, industries, and businesses, wherever we need the power. In spite of this critical role, it often goes unnoticed until a failure …
