Purchasing Guide

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

  • For procurement requirements that require the use of current transformers, it is recommended to prioritize confirming key technical parameters such as input and output voltage range, rated power, and frequency response to ensure compatibility with the equipment.
  • In scenarios such as industrial automation or new energy generation, the insulation level and temperature rise characteristics of current transformers need to be strictly screened according to environmental conditions to avoid overload risks.
  • 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.
  • For high-precision measurement scenarios, it is recommended to choose current transformers with a linearity error of less than 0.5%, while paying attention to industry application case data from suppliers.

Knowledge Base

Q

This article analyzes the selection method of transformer coil current density, and provides practical suggestions from three aspects: heat dissipation conditions, material characteristics, and load characteristics to help readers determine the current density value reasonably.

Q

The current of a transformer depends on the input voltage, output voltage, and rated capacity of the transformer. Generally, the current per kilovolt ampere of the transformer is between 1-5. This article will introduce the calculation method of current in transformers and the role of transformers in practical applications.

Q

The rated current of a transformer refers to the maximum current value that the transformer can withstand, usually the sum of the three-phase currents.
