2. Translation: Capacitive Voltage Transformer Core

Differences

1. Laminated Core Voltage Transformer Core ()

   • Structure: This type of core is made by stacking thin sheets of electrical steel, typically cold-rolled silicon steel, with insulating layers between them. The laminated structure helps reduce eddy current losses and improves the overall efficiency of the voltage transformer.
   • Applications: Commonly used in traditional electromagnetic voltage transformers where accurate voltage measurement and isolation are required in power systems. The core's lamination ensures low core losses, especially at high frequencies, making it suitable for standard voltage measurement and protection in power networks.

2. Capacitive Voltage Transformer Core ()

   • Structure: This type of core is part of a capacitive voltage transformer (CVT), which operates based on the principle of capacitance rather than a laminated iron core. The core might not necessarily be a traditional iron core and often involves capacitive dividers.
   • Applications: Used in capacitive voltage transformers that are designed for high-voltage applications, especially in electrical substations where space and weight are limited. CVTs are preferred in some systems for their compact design and ability to handle high-voltage measurements efficiently, especially in AC power systems.

Summary of Differences

• Laminated cores () are used in traditional electromagnetic voltage transformers and are constructed using iron laminations to reduce losses, ideal for standard voltage measurement applications.
• Capacitive cores () are part of capacitive voltage transformers, which rely on capacitive dividers rather than a traditional iron core to measure high voltages in a more compact and efficient way, especially for high-voltage applications in substations.
