Transformer Capacity Load No Load Tester

Transformer Capacity Load No Load Tester is specially used for measuring the capacity of distribution power transformer, measuring the no-load and short-circuit loss of transformer, and has the function of harmonic analysis, which is convenient for analyzing the quality of on-site power network. Transformer Capacity Load No Load Tester can automatically check whether the wiring is correct and display the vector diagram of the three-phase current and voltage when testing the three-phase transformer. At the same time, necessary correction (such as waveform correction, temperature correction, unrated voltage correction, calibration, unrated current correction) is introduced to make the test results more accurate.

• Measure the no-load current and no-load loss of the transformer; Short circuit voltage, short circuit (load) loss, capacity.
• Experimental method: Three tables.
• Transformer Capacity Load No-load Tester can automatically check whether the wires are connected correctly and display vector diagrams of three-phase current and voltage when testing three-phase transformers.
• A single machine can perform load tests on substation transformers below 1600KVA; It is possible to perform load testing on substation transformers with 1/3 of the rated current below 2500KVA (if the rated current is below 1/3 of the rated current, Transformer Capacity Load No-load Tester can be converted into load loss parameters)
• All relevant test results will be automatically corrected. Transformer Capacity Load No-load Tester can automatically perform non rated current corrections such as waveform correction, temperature correction, non rated voltage correction, and calibration, making the test results more accurate.
• 6.320x240 LCD display, user-friendly human-machine interface, brightness control, suitable for all seasons.
• Equipped with an electronic clock that automatically records data and time, which is beneficial for saving and managing test results.
• Panel printers can print test results on site.
• Data (sample settings, test results, measurement time) can be saved and viewed in the event of a power outage. It can store 500 sets of test results and can be connected to a computer for data transmission.
• Allow external connection of CT and PT for extended measurement, which can test any parameter of the sample.

The Transformer Capacity Load No Load Tester is an indispensable multifunctional and intelligent on-site testing equipment in the power system. It accurately measures core characteristic parameters such as no-load loss, load loss, and impedance voltage of transformers, which can not only effectively determine the actual capacity of transformers (for verification and anti electricity theft), but also serve as an important tool for evaluating transformer energy efficiency, inspecting manufacturing quality, diagnosing internal faults, and conducting preventive maintenance. Its application runs through the entire lifecycle of transformer manufacturing, installation, operation, maintenance, and retirement, and is of great significance for ensuring the safe and economic operation of the power grid, promoting energy conservation and emission reduction

1.Boot no display: first off, open the socket on the back panel AC 220V fuse box, check the fuse box, you can replace insurance.
2.The screen suddenly black screen: press the reset button, to start measurement.
3.Measurement and computation results are not correct: Check the external wiring, whether by manual operation, whether bad or take the wrong line; relevant parameter is incorrect.
4.Measuring voltage and current display to zero the normal, check whether the current file fuse blown
