Large Power Transformers

Large power transformers are in the power range above 250 MVA, generator and network intertie transformers with off-load or on-load tap changers, or a combination of both, are recommended. Depending on the on-site requirements, they can be designed as multiwinding transformers or autotransformers, in 3-phase or 1-phase versions. Even with ratings of more than 1,000 MVA and voltages up to 1,200 kV (800 kV), the feasibility limits have not yet been reached. We manufacture these units according to IEC 60076 as well as other international and national standards (e.g., ANSI/IEEE).
Generator step-up (GSU) transformers
GSU units transform the voltage up from the generator voltage level to the transmission voltage level, which may be as high as 1,200 kV system voltage. Such transformers are usually YNd-connected.
In order to make an inquiry regarding a GSU power transformer, the technical data for the items in this section are required.

Step-down transformers
Step-down transformers transform the voltage down from the transmission voltage level to an appropriate distribution voltage level. The power rating of step-down transformers may range up to the power rating of the transmission line.

System interconnecting transformers
System interconnecting transformers connect transmission
systems with different voltages together so that active as well as
reactive power can be exchanged between the systems.

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. Tinde Power is your partner, who picks up these requirements converting them into convincing solutions with maximum quality. Power Transformers that render their service reliably at site.

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.

Overview

Current transformer volt-ampere characteristic tester Only need to set the test voltage, current and step, the device will boost and trace voltage current characteristic test curve automatically, save the cumbersome labor of manual pressure regulation, artificial record, tracing curves, and so. Quick, simple and convenient.

I can not only test CT/PT DC resistance, volt-ampere characteristics, ratio and polarity, 10% error curve, angle difference and ratio difference, but also test secondary load of transformer, CT current test and PT AC withstand voltage test.

CT ratio not only supports traditional current method but also voltage method, so it can meet the test of CT in casing CT and GIS.

Volt-ampere characteristic test single machine output voltage 0-2500V, current 0-20A, can meet most of the transformer volt-ampere characteristic test.

220V single power input and avoids the risk of using 380V.
