The main line connection mode used in power transformation and distribution

Electrical wiring in substation includes primary circuit wiring and secondary circuit wiring. The primary circuit, also known as the main circuit, refers to the circuit through which the electric energy flows. The main equipment includes generators, transformers, circuit breakers, isolation switches, lightning arresters, fuses and voltage and current transformers, etc. The wiring of the main […]

2022 cost-effective true wireless collar microphone selection guide: live, short video Vlog recording

Wireless lapel microphone, a type of wireless microphone, has become popular recently. It is a small, small and portable microphone, usually worn in the location of the user's clothing lapel. It can be freed from the cable, and the user can do whatever he or she wants without worrying about the sound. It is generally […]

inductance

Inductor is usually called the feeling, the self inductance coil is called inductance, mutual inductance coil is called transformer, they are all with enameled wire, cotton covered wire or plastic skin line in insulation skeleton or core (typically high-frequency transformer), iron core made of round a set series of electromagnetic induction of coaxial circle element, […]

The role of video optical transceiver in monitoring field

Video optical transceiver is the equipment that converts 1 to multi-channel analog video signals into optical signals through various codes and transmits them through optical fiber medium. As video signals are converted into optical signals through analog conversion and digital conversion technologies, video optical transceiver is divided into analog optical transceiver and digital optical transceiver. […]

Hall element optocoupler

Hall element is a device that applies hall effect. The so-called Hall effect was discovered by American physicist Hall in 1879. It refers to the physical phenomenon of transverse potential difference when the magnetic field acts on the carriers in the current-carrying gold conductor and semiconductor. When electric current through the metal foil, if the […]

Ten common errors encountered by hardware engineers in circuit stability design

There are not only a lot of techniques in circuit design, but also a lot of mistakes. This paper introduces ten errors in circuit stability design. Myth 1: Product failure = unreliable product Products appear problem, sometimes not r&d problems, there have been cases, geared to the needs of domestic medium above equipment developed regions, […]
