  1. Transformer Barrier:
  • In transformers, a barrier refers to a solid insulating material that provides primary insulation, separate from the transformer oil.
  • This insulation is crucial for preventing electrical breakdown between different voltage levels and ensuring the safe operation of the transformer.
  1. Circuit Breaker Barrier:
  • In the context of circuit breakers, a barrier is a refractory material designed to localize or direct any arc that may occur during the operation of the circuit breaker.
  • Arcs can occur when a circuit breaker interrupts the flow of electrical current, and barriers help contain and redirect these arcs to prevent damage to the breaker and surrounding components.
  • These barriers are typically made from materials that can withstand high temperatures and effectively manage the energy released during arcing events.

These definitions highlight the critical role barriers play in maintaining the safety and reliability of electrical equipment like transformers and circuit breakers by providing insulation and managing arc energy effectively.
