10kV Two-Core Current Transformers
About the Product
The EWF-10D Series two-core current transformers are designed for 12 kV (max.) power systems and intended to be used with measuring (or monitoring) instruments and protective relays. Insulated with Araldite® epoxy resin, these current transformers meet the requirements of all major electrical standards. In addition to superior insulation, these products are also characterized by high mechanical properties and excellent resistance against moisture.

For use in conjunction with energy meters or protective relays. Available in single-core, 2-core, and 3-core models. Insulated with Araldite® epoxy resin. Custom-made to meet various requirements.
Cut-core, medium-voltage, indoor-use, coil molded current transformer intended for a 12kV (max.) power system and suited for measuring or monitoring instruments. Insulated with Araldite® epoxy resin.
Single-core and 2-core indoor window-type current transformers for power systems ≦ 15kV. Primary current: 500~3000A (single-ratio or multi-ratio). Araldite® epoxy resin. Used with measuring or monitoring instruments, or for protection.
When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
