Parts and Materials Cross References Learning Objectives Schematic Diagram Illustration Instructions Current is the measure of the rate of electron ”flow” in a circuit. It is measured in the unit of the Ampere, simply called ”Amp,” (A). The most common way to measure current in a circuit is to break the circuit open and insert … Read more
Transmission line insulators perform two tasks. They electrically isolate transmission lines from the ground and they provide mechanical support to conductors. HV Engineers are involved in different types of insulator testing so as to ensure the reliability and proper working of power systems. Today you’ll learn about top 10 Insulator tests that are performed on transmission … Read more
A circuit is a closed loop or pathway through which electric current can flow. It typically consists of various electrical components, such as resistors, capacitors, inductors, and semiconductor devices like transistors and integrated circuits, connected by conductive wires. The components in a circuit work together to perform specific functions, such as amplifying signals, processing information, … Read more
Ohmmeter Usage Tutorial Download article PDF here or continue reading below Parts and Materials This experiment describes how to measure the electrical resistance of several objects. You need not possess all items listed above in order to effectively learn about resistance. Con- versely, you need not limit your experiments to these items. However, be sure … Read more

Digital multimeters have numerical displays, like digital clocks, for indicating the quantity of voltage, current, or resistance. Analog multimeters indicate these quantities by means of a moving pointer … Read more
A radial feeder is a type of power distribution system in which electrical power flows from a single source or substation to various endpoints or loads in a unidirectional manner. The term “radial” is used to describe the structure of the feeder, which resembles the branches of a tree radiating outward from a central point. … Read more
A Stockbridge damper is a tuned mass damper that is used to suppress wind-induced vibrations on overhead power lines. Stockbridge damper is the dumbbell-shaped device that comprises of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main cable. The damper is … Read more
