Current Transformer & Voltage Transformer

Power transformers or electrical transformers are used to transform electrical energy by altering voltage, generally from high to low. Voltage is simply the measurement of electrons in the flow. Through power transformers, electricity can be transported more easily and efficiently over long distances.
The most common and the most necessary use of various power transformers is the transportation of electricity from power plants to homes and businesses. Since power often has to travel a long distance, it is transformed first into a more manageable state. Then the power is transformed again and again, or stepped down, repeatedly as it gets closer to its destination.
When the power leaves the plant, it is usually of high voltage. When it reaches the substation the voltage is lowered. When it reaches a smaller transformer found on top of electric poles, it is stepped down again. It is a continuous process, which repeats until the power is at a usable level.
Electric power distribution is now more efficient than ever. Transformers have made it possible to transfer power near and far, in a timely, efficient and more economical manner. Since many people do not wish to live close to a power plant, power transformers are necessary to provide dependable and affordable electricity for homes and businesses that are quite a distance from power plants. Much of the electricity used today has passed through many electrical transformers before it reaches users.

We are a major power transformer manufacturer in China, located in Wenzhou, Zhejiang province, being next to East China Sea.
