Bushing type current transformers

BCT is one of the accessories which with rather low prices can add considerable capabilities to power transformers as the most expensive equipment of high voltage substations. The Type of current transformers can be used in any other high voltage equipment containing earthed shields around the current carrying conductor. The CT can be used in dry conditions either, although it is advised to oil impregnated after dring to avoid the deteriorating effects of oxygen in air. The following table includes the summary of the specifications which can be covered.

Bushing type current transformers NirouTrans
1) Different secondary currents can be offered, depending on customer’s requirements.
2) ALF can be from 5 to 100 depending on the rated burden and current.
3) Depending on the rated current, higher burden can be offered.


In the type of CT, double enameled wire is used and the insulation is applied with superior world quality crepe paper and poly propylene tape.
The wire ends o the core are protected against any damage by he use of the best quality insulating hoses available on the world market today. The connection cable used for the terminals are oil and heat resistant appropriate for using specially in power transformers. If it is required by the customer, the CT can be equipped with primary best lead terminal made with flexible copper wire with cross sectional area 35mm2.
