Current transformer is a very useful electrical equipment

Current transformers are electrical devices useful because it can be converted to high AC current can be easily controlled, low current. The current  Electric transformer  winding, the secondary winding, the core and the insulator composition, if the bus without a transformer, the  circuit breakers  the manufacturing process for the first time there is no winding. In contrast, in each susceptor through the conductor or bus may be configured as a primary winding.
Current  air circuit breaker  according to IEC44-1 production, and the secondary terminals below the transparent protective cover. Measuring voltage and current transformers are two types of protection.
