FAQ

Q:What is the difference between 5P20 and PX class current transformer

A:The main difference between a 5P20 current transformer (CT) and a PX class current transformer lies in their accuracy and application. The 5P20 CT is a protection type current transformer with an accuracy class. The designation "5P" indicates that the transformer will not exceed an error of 5% under rated secondary burden when the secondary current reaches 20 times the rated current. This type of CT is typically used for overload protection and is not suitable for precise measurements. A PX class CT refers to a current transformer with a specific accuracy class for precise measurements. PX class CTs have different accuracy levels, such as 0.2S, 0.5S, etc. These figures indicate the percentage of error allowed under specified conditions. PX class CTs are commonly used for metering and billing purposes because they offer higher measurement accuracy. In summary, 5P20 CTs are primarily used for protection purposes, while PX class CTs are used in situations where high accuracy measurements are required.
