Earth testers, essential in electrical engineering, measure the resistance between electrical installations and the ground. This measurement ensures that electrical systems have proper earthing, providing a safe path for fault currents and preventing potential hazards. They help confirm that the earth resistance remains low, ensuring fault currents dissipate without endangering people or damaging equipment. What … Read more
A Strain or tension-type insulator is a type of electrical insulator designed to withstand mechanical tension or stress in addition to providing electrical insulation. These insulators are used in power transmission and distribution lines where conductors (wires or cables) need to be supported while being kept electrically isolated from supporting structures, like poles or towers. … Read more
A suspension type insulator is a type of electrical insulator used in high-voltage transmission and distribution systems. It is designed to suspend the overhead conductor or power line and electrically isolate it from the supporting structures, such as towers or poles. This ensures that electrical energy is transmitted safely without leaking to the ground or … Read more
The overhead lines conductors Pin type insulator should be supported on the poles or towers in such a way that currents from conductors do not flow to earth through supports. The insulators provide necessary insulation between line conductors and supports and thus prevent any leakage current from conductors to earth. Properties of Good Insulators- ❑High … Read more
bus bar in electrical is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. The electrical bus bar is available in rectangular, cross-sectional, round and many other shapes. The rectangular bus bar is mostly used in the power system. … Read more
Resistor is a component which is used to limit the flow of current. The passive component which offers a specified value of resistance in the circuit is known as a resistor. Resist means to oppose. All the materials offer a little or more opposition to the flow of electric current through them. The property of … Read more
A vcb full form in electrical Vacuum Circuit Breaker (VCB) is a type of electrical circuit breaker that uses a vacuum as the arc-quenching medium. It is a popular choice for medium-voltage applications due to its reliability, low maintenance, and environmental benefits. The vacuum has the highest insulating strength. So, it has far superior arc … Read more
The sensitivity (gain) and frequency bandwidth (B.W) response characteristics of theoscilloscope are mainly determine by the vertical amplifier .Since the Vertical amplifier and Horizontal deflecting system in oscilloscope gain-B.W. product is constant, to obtain a greater sensitivity the B.W. is narrowed, or vice-versa. Some oscilloscopes give two alternatives, switching to a wide bandwidth position, and … Read more

The Curie Point, also referred to as the Curie Temperature, is the specific temperature at which a material undergoes a significant change in its magnetic properties. Named after the physicist Pierre Curie, this point marks the temperature at which a material transitions between different magnetic phases. Below the Curie Point, a material tends to exhibit … Read more
