BS0207 Transformer Low Voltage Short Circuit Impedance Tester

Product Introduction

The BS0207 transformer low-voltage short-circuit impedance tester is used for measuring transformer no-load and load parameters. The transformer low-voltage short-circuit impedance tester can accurately measure a series of parameters such as no-load current, no-load loss, short-circuit loss, and impedance voltage of various transformers; Conducting short-circuit impedance testing on power transformers and comparing them with nameplate or factory values can reveal defects such as winding displacement and deformation caused by severe fault currents during transportation, installation, and operation after factory testing; The device allows external current transformers and voltage transformers to expand their range for measurement. The maximum voltage can be measured up to 750V, with automatic switching, large screen display, and touch buttons for easier operation. It is mainly suitable for low voltage short-circuit impedance testing of power transformers (single-phase or three-phase) during factory, overhaul, pre testing, and handover testing. It is an essential maintenance tester for transformer production enterprises and power maintenance enterprises.

The main functions of the BS0207 transformer low-voltage short-circuit impedance tester include: black and white screen display, automatic waveform distortion correction, temperature correction, voltage correction (no-load test under non rated voltage), current correction (short-circuit test under non rated current conditions, taking 20% -70% of the rated current), additional loss correction for short-circuit test. Personnel only need to input the correction index tester according to the transformer type to automatically calculate the corrected results.

Product Features

1. Without the need for an external voltage regulator, the tested product can be measured.

2. The instrument uses a 220V low-voltage power supply to automatically apply current to the three-phase high-voltage winding of the transformer, synchronously collect data, and automatically calculate the impedance error percentage. The test results are very intuitive.

3. Equipped with output current limiting function, suitable for any impedance test sample.

4. The instrument operation is very simple, with one-time wiring, and can automatically complete three-phase testing without reversing the test wire.

5. For three-phase transformers, the instrument can be used for single-phase testing, three-phase testing, manual testing, or automatic testing.

6. Capable of measuring zero sequence impedance

7. Capable of measuring inductance

8. Using a large screen LCD display and a fully Chinese menu style operation, the test can be completed according to the prompts on the screen.

9. It has printing and storage functions, with 232 serial port and USB storage, making it easy to analyze and organize data.

10. Simple wiring, accurate testing, high level of automation, small size, and light weight.
