Transformer characteristic capacity tester

Overview

Transformer characteristic capacity testerWith the development of the power industry and the application of new materials and processes, new energy-saving transformers have been constantly updated and upgraded in recent years, moving towards low loss and small size. Due to the operation of multiple forms of transformers on the power grid, it is difficult to distinguish the rated capacity of transformers based on their volume when the nameplate is lost or the handwriting is unclear. This instrument is used by the maintenance departments of transformers in power, railway, petroleum and other systems to quickly and accurately test the relevant parameters of transformers such as no-load current, no-load loss, impedance voltage, load loss, etc., and infer the transformer capacity through specialized software, overcoming the problems of traditional measurement instrument reading, complex wiring, asynchronous readings, and large measurement errors. To provide the necessary parameters for monitoring or retrofitting transformers, ultimately serving the ultimate goal of reducing losses, saving energy, and ensuring safe operation.

Main functions and features

This instrument uses advanced DSP digital signal processing as the control and operation core, with efficient and accurate operation. The voltage and current ranges do not need to be pre-set, and automatic range switching is achieved.

It can be directly tested using the mains test power supply.

■ It is convenient to support the analysis and storage of test data, and a micro printer is configured for users to choose whether to print the data.

The instrument can display the measured waveforms of voltage and current. You can observe the waveforms of voltage and current without connecting the oscilloscope probe. The instrument is also equipped with a high-precision humidity sensor, which can display the temperature inside the chassis and provide reference for on-site testing.

It can automatically determine the rated capacity and type of the tested transformer based on on-site testing parameters, and calculate the deviation of characteristic parameters from the national standard.

It has automatic data storage function, with a storage capacity of no less than the rated parameters of 5 transformers, and can be saved for a long time after power failure, and can be queried at any time.

Equipped with a computer interface, it can achieve real-time data transmission with a repeater.

Provide management software that enables communication, storage, querying, data analysis, printing of test reports, and more.

This instrument adopts a Chinese menu, intuitive interface, keyboard control for measurement, high degree of automation, and easy operation and wiring.

The instrument is small in size and light in weight, making it easy to carry.
