What parameters can the transformer on load tap changer tester test?

Transformer on load tap changer (OLTC) is a mechanical device used to regulate the voltage and current of a transformer, change the effective number of turns, and adjust the parameters of the transformer (capacity, voltage, current). It plays an important role in the power system, so we need to regularly inspect it. At this time, we need to use a transformer on load tap changer tester, So what parameters can it test? Below are some examples for everyone.

The transformer on load tap changer tester can test the following parameters:

1. Transition time: reflects the speed of the on load tap changer action of the transformer and the stability during switch switching.

2. Transition waveform: Reflects the waveform situation during switch switching, which helps to understand the switching principle of the switch and evaluate its working state.

3. Transition resistance: Reflects the change in resistance value during switch switching, and understands the switching situation of the switch by measuring the transition resistance.

4. Three phase synchronicity: It reflects the synchronicity of the switching of the three-phase on load tap changer, which affects the operational stability of the transformer.

5. Potential faults: Help identify and solve potential problems with transformer on load tap changers, ensuring safe and stable operation of transformers.

6. Current, voltage, temperature and humidity: These three parameters are the basis for measuring the on load tap changer tester of transformers, and can help understand the working and environmental conditions of transformers.

7. Resistance change: By testing the resistance change and analyzing the current change during switch switching, the performance of the switch can be judged.

8. Humanized data analysis: Through user-friendly software interfaces, the testing and data analysis process can be simplified, greatly improving work efficiency.

9. Automatic adjustment of waveform display: This function can automatically adjust the waveform display based on test data, making the waveform clearer and easier to analyze.

10. Can be tested with or without windings: It can be used for various types and specifications of transformers, achieving wide applicability of equipment.

The comprehensive function of the transformer load switch detector is very powerful, which can help us power workers to do a good job in daily maintenance and repair of transformer load switches. It is a blessing for us power workers.

ZC-220 transformer on load tap changer tester is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, three-phase synchronization, etc. of transformer on load tap changer. The instrument has small volume, light weight and strong anti-interference ability, which greatly reduces the labor intensity of on-site staff. It is an ideal instrument for power generation and power supply units and transformer manufacturing industry to ensure safe production and improve product quality.
