Current transformers costs

07/27/2008 11:16 AM

In an industrial project, the customer decided to change first order for new power transformer. According to new order, the rating power of transformer should be half. He enquired new detail cost table and transformer manufacturer submitted it. Future power transformer user cheeked that mentioned list; he noted all detail items cost decreased approximately except bushing current transformers costs. He can not understand the reason of this cost impact.

How can you explain the reason of BCT cost increasing due to its turn ratio decreasing?

Could be a number of reasons. How about the fact that it is a CT and changing to a smaller, cheaper transformer doesn't mean changing to a smaller, cheaper CT. Could be the CT needed to be custom made or designed due to the customers new requirements. Could be the CT needed to be sourced from a new supplier due to the design or transformer bushing size changes.

Could be any number of reasons. Call or email your supplier directly and ask them yourself.
