Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of AC current transformers, it is recommended to prioritize confirming key technical parameters such as rated current ratio, accuracy level, and frequency range to ensure compatibility with power monitoring or energy metering systems.
  • In industrial automation or new energy generation scenarios, suitable protection levels (such as IP54 or higher) and structural types (open or closed) of AC current transformers should be selected according to the installation environment.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance technical adaptability and supply chain stability.
  • For different application scenarios (such as distribution cabinet integration or high-voltage line monitoring), it is recommended to select based on the type of secondary output signal (such as 4-20mA or 0-5V) and the interface requirements of the backend equipment.

Knowledge Base

Q

Current transformer is one of the indispensable and important components in the power system. If it is selected too small, it will have a negative impact on the entire system. This article will introduce the consequences and countermeasures of selecting a smaller current transformer.

Q

This article systematically introduces three practical methods for open circuit demagnetization of AC current transformers, including DC demagnetization method, AC demagnetization method, and natural demagnetization method. Detailed analysis of the operation steps and precautions is provided to help technicians safely and efficiently complete demagnetization operations.
