High-voltage circuit breakers used on transmission systems may be arranged to allow a single pole of a three-phase line to trip, instead of tripping all three poles; for some classes of faults this improves the system st…Mais

In electronics, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The most familiar form of switch is a manually operated el…Mais

In an electric power system, switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize eq…Mais

Oil Circuit Breaker a high-voltage AC electrical switch whose main contacts are located in a space filled with mineral (transformer) oil. Upon interruption of the electric circuit, an electric arc forms between the conta…Mais

Power transformers where the winding insulation is used transformer oil

Power transformers are the main element of power electrical substations in electrical systems, urban, regional or other level and are designed to increase/decrease voltages in electric networks (tens to hundreds of thous…Mais

Machines, apparatus and devices used to perform technical or production tasks.

A type of integrated circuit device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing, power amplification, low-noise amplification, and high-…Mais
