Earth leakage circuit breaker An earth leakage circuit breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock.hese devices sense a voltage to decide the earth leakage. A single phase voltage-ELCB will have six terminals. Line in, Line out, neutral in, neutral out, Earth and Fault. Metal body of the load is connected to the fault terminal of ELCB and Earth terminal is connected to the ground.

Practical Electronics/Crowbar circuit Practical Electronics/Crowbar circuit. A crowbar circuit is a method of protecting a circuit against high voltages (overvoltage) in the event of a power supply malfunction or power surge. This is especially useful in a device using TTL components as these are very sensitive to overvoltage.

- In this demonstration you will use an instrument called a galvanometer. It is an instrument with a bar of iron wrapped with an electrical wire, and a magnet. It detects electrical current. If a wire is connected to this instrument, it can detect if electricity is flowing through the wire. If there is no current through the wire, the needle will move to the left. Similarly, if there is a current flowing through the wire, the needle will move towards the right of the scale. This demonstration should help to give you an idea of the relationship between magnetism and electricity.

Electric Service Drop: Basics and FAQs An electric service drop is the main electrical line that runs from the electric company's overhead lines to the service head at your house. Because power company lines are higher than your home, the feeder line that goes to your home literally drops--it descends from a higher spot to a lower spot.

- Medium voltage electronic sectionalizers AutoLink. The ABB AutoLink sectionalizer is an isolating device that automatically isolates the faulted section of the network when a permanent fault occurs. If a temporary fault occurs, the AutoLink allows the upstream recloser or breaker to clear the fault without interrupting the circuit. It is a simple and economic solution for MV overhead lines sectionalizing, towards creating a smart grid and grid optimization.

Coaxial Feeder / RF Coax Cable Tutorial Applications of coax cable. Coax cable or coaxial feeder is used in many applications where it is necessary to transfer radio frequency energy from one point to another. Possibly the most obvious use of coax cable is for domestic television down-leads, but it is widely used in many other areas as well.he most common type of antenna feeder used today is undoubtedly coaxial feeder or coax cable. Coax cable, often referred to as RF cable, offers advantages of convenience of use while being able to provide a good level of performance.
