Why do optical cables carry an electric charge
While fiber optic cables do not directly carry electricity, they can be used to convert energy from light into electrical energy. Each strand is roughly the width of a human hair, yet a single fiber can carry hundreds of gigabits of data per second over distances that would cripple a. Bits will travel across several different physical media on their way to your device. When an electric charge is present, a 1 is transmitted. When an electric charge. Besides the use of special cables on transmission and distribution towers or poles, the installation of fiber optic cables for utilities may require the shutdown of electrical distribution for installation, although some installations are possible without shutdown. This allows a device to be remotely powered, while providing electrical isolation between the device and the power. Toslink—short for “Toshiba Link”—is a very specific subset of fiber‑optic technology created in 1983 to move consumer‑level digital audio from one box to another. -

What does a relay protection major do
Their primary responsibility is to design, implement, and maintain protection systems that detect and isolate faults in the power transmission network. It functions as a watchdog by constantly surveying multiple system components including voltage, current, frequency, and phase angle. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. A protective relay definition is; a switchgear device used to detect faults & begin the circuit breaker operation to separate the faulty element of the system. The terminals of the relay mainly include; common, coil, NO (normally open) & NC (normally closed). -
