Medium Power Transformers

Medium power transformers with a power range from 40 to 250 mva and a voltage of over 72.5 kv are used as network and generator step-up transformers. Medium power transformers are also widely used to step up power from on- and offshore-windparks, and may even be installed in offshore-substations.
Bringing the energy safely to the consumer: a basic requirement applicable to all power transformers. However, every single one is unique designed according to individual factors such as voltage, power, climate, system topography, sound level and many more.

Tungwell also offers a wide variety of power auxiliaries and materials available for all your power generating, transmission, distribution and protection needs.

We offer a full range of customer supports for all products & equipment that we support and manufacture, such as genuine engine parts for generating sets and Gas Turbines, Protection devices as CT, PT, SA, T&Dline hardware, etc.

Product description

Transformer calibrator is a new automatic instrument. We apply advanced electronic technology in the design. By directly decomposing the error signal, it is able to display the percentage, phase error and orthogonal error statistically. It s quick and energy saving. And it s especially good for live testing due to its cute dimension and light weight.

Using Methods and Attention Matters

1.Check the test transformer measuring winding rated output voltage, and make it match the operation box correctly.

2. Connect the line between test transformer and operation box according to the wiring diagram.

3. Switch on the power supply, then close the knife switch, and the power indicator light, finally set the work time of relay.

4. Make the pressure regulator display zero, press the start button, the clockwise rotation of the hand wheel, until it reaches the required value.

5. Start the timing switch, timing begins, the electric bell will alarm automatically when it reaches the setting time(artificially controlled time if there is on alarming function), then break off the timing switch.



Q&A:

What is the difference between a control box and a box-type transformer



The control box has only control functions. It is a control unit. Its main function is to issue instructions to control the rapid breaking of the circuit breaker in the box substation; it is a component in the box substation.

The box-type transformer generally refers to the box-type substation, which integrates the functions of power transformation, power distribution, control, and protection.
