10kV Multi-Ratio Current Transformers (Single-Core & Two-Core Types)
MV Window-Type Epoxy-Cast CT
About the Product
Intended for 15 kV (max.) power systems, the EO-10SC Series current transformers for indoor application are available in single-core and two-core types. With a rated primary current of 500~3000A (single-ratio or multi-ratio), these current transformers are insulated with Araldite® epoxy resin and can be used with measuring or monitoring instruments, or for protective purposes. The window-type design facilitates installation and wiring with a busbar or a suitably insulated primary conductor, decreasing the occurrence rate of contact point failure. Characterized by excellent physical and electrical properties, the EO-10SC Series current transformers have consistently met with a high level of customer satisfaction.

2-core current transformers designed for 12kV (max.) power systems for use with measuring (or monitoring) instruments and protective relays, these products are cast in Araldite® epoxy and meet the requirements of all major electrical standards.
Current transformers for installation in a switchgear panel of a 25kV (max.) power system and to be used with measuring or monitoring instruments, or protective relays. These are economic models suited to locations of high humidity or moderate pollution. The insulation material for the core and the secondary coil is Araldite® epoxy resin.
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.
