The additional burden imposed on primary current transformers by auxiliary current transformers can lead to increased errors in measurement.
  • Furthermore, the performance of auxiliary current transformers may not be as precise as primary transformers due to their design and operational restrictions. These are used in various applications, including power plants, electricity grids, control rooms, switchgears, and metering purposes. They are available in various types, such as toroidal, wound type, oil immersed, and digital current transformers, with different voltage ratings and cooling methods. While current transformers are essential for power transmission and distribution, they come with challenges, such as cooling, oil leakage, health hazards, and fire risks. Despite these challenges, current transformers remain indispensable components of power systems, enabling accurate current measurement, real-time data, load monitoring, fault detection, power quality analysis, and grid integration.

What challenges does the Current Transformer Industry face during its growth?

  • High cost of upgrading electricity distribution networks is a key challenge affecting the industry growth. The electricity sector is experiencing significant growth due to population expansion and urbanization, leading to increased demand for current transformers in power systems. Current transformers are essential components in measurement, monitoring, protection, and power flow control in electrical power systems.
