250 Kva 3 Phase Transformer Power Transformer

The 250 Kva 3 Phase Transformer Power Transformer is an oil immersed distribution transformer with automatic load regulation function. Its core purpose is to convert the 10kV input voltage into a 0.4kV output voltage. It is suitable for industrial and commercial environments with significant voltage fluctuations and the need for stable output.

The entire production process of the 250 kva 3 phase on load tap changer power transformer strictly follows the IEC and GB standards of the power industry. From material selection to the final product, every step is meticulously controlled. Specialized processes are equipped with a voltage structure that can adjust the load, to ensure the stability and reliability of the voltage regulator during frequent switching, and the overall electrical voltage regulation is precise, with low losses and smooth operation.

In addition, the factory inspection will conduct a series of experimental tests on the 250 kva 3 phase on load tap changer power transformer. For example, DC resistance tests, ratio and group type tests, no load loss, load loss, short circuit impedance measurement, power frequency withstand voltage, induction withstand voltage, partial discharge tests, and full range position switching tests of the loaded voltage regulator, etc.This is done to ensure that every transformer produced is safe, reliable and stable.

How to choose a on load tap changer transformer or an off load tap changer transformer?

The main advantage of a on-load tap-changer transformer like our 250 Kva 3 Phase Transformer Power Transformer is that it can adjust the voltage while the power is on, without the need for power outage; while a general off load tap changer transformer requires a power outage and manual voltage adjustment.

1.From the perspective of selection, if the power supply voltage in your area is unstable, the load is unstable, and the voltage quality requirements are relatively high, and you need to adjust the voltage frequently, then you should choose a on load tap changer type transformer,such as our 250 kva 3 phase on load tap changer power transformer ,which is designed to meet these demands.

2.From the perspective of reliability, if your production process is continuous and the voltage fluctuates frequently, then choosing a on load tap changer transformer will improve the reliability of power supply.

3.The voltage adjustment part of the on load tap changer transformer uses a circuit breaker, which can cut off the current and arc generated by each tap connection during the voltage adjustment.This allows our 250 kva 3 phase on load tap changer power transformer to adjust the voltage stably while carrying a full load, ensuring continuous power supply.
