Insulation Resistance

insulation resistance

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 …

ELECTRICAL FAULTS

Electrical faults

Electrical Faults are abnormalities of electrical parameters, either voltage or current, or both in a stable power system. Electrical 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 …

OVER VOLTAGE

Over voltage

Over voltage is an occurrence in a power system when the voltage goes beyond the rated threshold of the system. Over voltage occurs in a system and persists for a very short time. Voltage is a stress and overstressing can result in subsequent damage to the electrical equipment …

Basic Insulation Level

Basic insulation level

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

busbar

Bus bar 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 is used at all voltage-level …

GIS: GAS INSULATED SWITCHGEAR

GIS

A GIS or gas-insulated switchgear substation is a compact, metal-enclosed structure that houses high-voltage switchgear, busbars, and other electrical equipment. Unlike conventional Air Insulated Switchgear (AIS) Substations, which use open-air configurations, GIS substations utilize sulfur hexafluoride (SF6) gas as an insulating medium within metal-enclosed units. This design not …

AIS: AIR INSULATED SWITCHGEAR

AIS

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. Working Principle The basic working principle of …

SUBSTATION

substation

Substations are part of an electrical power system which plays a very important role in the generation, transmission, and distribution of electricity. It serves as an intermediary point between the source and load distribution networks. The main functions of substations include voltage transformation, switching, and protection of the …

Transmission Lines

transmission lines

What Are Transmission Lines? Transmission lines are high-voltage power lines that carry electricity over long distances from generating stations to substations. These lines are essentially conductors, through which electricity flows, ensuring that energy, which is produced in remote generating plants, reaches urban and rural load centers with minimal …
