Check whether the transformer insulation strength can withstand full voltage or operational overvoltage shocks.Shock test can effectively check the operation of the transformer under full voltage or operational overvoltage, and verify whether its insulation performance meets the requirements.
What are the consequences of running transformers in parallel with unequal ratios?
2025.05.22
In the power system, transformer is one of the key equipments, which is used to realize the conversion of voltage and transmission of electric energy.However, when transformers are operated in parallel, if the ratios are not equal, a series of serious consequences will occur.This paper will discuss this in depth and analyze its potential impact.
How does a transformer transform voltage?
2025.05.22
The principle of transformer voltage transformation is based on the principle of electromagnetic induction.A transformer has two main building blocks: a primary coil and a secondary coil, both of which are wound on an iron core.When an alternating current is passed through the primary coil, an alternating magnetic field is generated in the core.This alternating magnetic field generates an induced electromotive force in the secondary coil.
What types of transformer designs are available?
2025.05.22
Based on their use, transformers can be categorized into power transformers and special transformers.Power transformers are used to step up or step down the voltage of the power system, while special transformers are used to meet specific needs, such as electric furnace transformers, rectifier transformers, mining transformers and so on.
Why can't a transformer be overloaded?
2025.05.22
When the transformer operating current exceeds the rated current, it is in overload operation.At this time, the load loss of the transformer increases sharply, which will lead to an increase in transformer temperature.The temperature of the insulation aging plays a decisive role, research statistics show that the temperature of the insulation components and materials work every 8 ℃, its life will be reduced by 50%.
