Power transformers with air-cooling, called dry transformers. Natural air cooling, the heat from the heated parts of the transformer a natural flow of ambient air, is sufficient for a small power transformer to winding v…More

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying m…More

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…More

Power transformers where the winding insulation is used transformer oil

Transformers are sometimes used to match the impedances of circuits. A transformer converts alternating current at one voltage to the same waveform at another voltage. The power input to the transformer and output from t…More

Electronic transformers

Transformers are designed for measuring electrical quantities: voltage, phase shift, or voltage. Are divided into current transformers and voltage transformers. The measurement transformer shall be calculated in such a w…More

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…More

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…More

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…More
