What is the difference between low voltage transformer and high voltage transformer?
High-voltage transformers and low-voltage transformers are two different types of transformers use in power systems. Their main differences lie in the voltage levels and application scenarios they are use for.
High-voltage transformers are commonly use to measure or monitor current and voltage in high-voltage systems, usually in power transmission systems, substations, etc.
Low-voltage transformers are usually use to measure or monitor current and voltage in low-voltage systems, such as industrial power, internal power distribution in buildings, etc.
The insulation and insulation materials of high voltage transformers usually need to be more stringent to cope with the high voltage environment, so their design and manufacturing costs are usually higher.
Low-voltage transformers can use simpler designs and materials because insulation requirements are relatively low at low voltages.
High voltage transformers are use in large power systems such as transmission grids and substations to monitor and measure power transmission.
Low voltage transformers are often use in small power systems, such as those inside factories and buildings, to control and monitor power usage.
Since high voltage transformers are typically use in larger power systems, they typically have higher accuracy and greater load capabilities to accommodate higher current and voltage levels.
The accuracy and load capacity of low-voltage transformers may be relatively low because the voltages and currents they face are usually small.
To sum up, there are significant differences between high-voltage transformers and low-voltage transformers in terms of voltage level, structural design, application scenarios, accuracy and load capacity. Therefore, when selecting a transformer, you need to consider the specific application requirements.

In Egypt you must pick the CTs with care. The need is strongest, in Cairo, Alexandria and Suez because the electric grid often changes, gets hot and carries loads. When the CTs are not stable or not accurate the safety system can fail. I have seen that the switchgear, the fuse breakers and the CTs… Continue reading How to Choose the Right Current transformer in Egypt
