The role of an electricity transformer is to modify the voltage level between circuits. It can increase (increase) or decrease (decrease) voltage levels while maintaining the same frequency. This is crucial for efficient electricity transmission and distribution, allowing electricity to be transported over long distances and then used safely in homes and businesses.
A current transformer is used to measure and monitor electrical currents in high voltage systems by producing a lower proportional current that can be safely measured with standard instruments.
It isolates measuring instruments from high voltage and provides accurate readings for protection, control and measurement purposes.
You need a transformer when there is a need to change voltage levels in an electrical system, either to meet the voltage requirements of different equipment or to improve the efficiency of power transmission. Transformers are essential for adjusting voltage to appropriate levels for safe and efficient use in various applications.
An electrical transformer works on the principle of electromagnetic induction.
It consists of two or more coils (windings) wound around a core. When alternating current (AC) flows through the primary winding, it creates a magnetic field which induces a voltage in the secondary winding. The voltage is varied depending on the turns ratio between the primary and secondary windings.
An EDF (Électrcité de France) transformer works in the same way as other electrical transformers, converting voltage levels according to different stages of the electrical power system.
EDF transformers are used on the French national grid to increase voltage for efficient transmission over long distances and to reduce it for distribution to residential and commercial users.
