24 kV Two-Core Current Transformer (“U-Shaped Top” Design)
EWF-20DI
2-core epoxy-cast current transformer for a 24 kV (max.) power system. For use with measuring or monitoring instruments, and protective relays. “U-shaped top” design for safety and for a shorter distance between two current transformers installed side-by-side, thus reducing the required width of the switchgear panel.
24 kV Two-Core Current Transformer (for Polluted Regions)
EWF-20DK
2-core current transformer for a 20~24kV power system. Used in conjunction with measuring or monitoring instruments, and with protective relays. Epoxy cast. Designed to have greater creepage, it is appropriate for polluted regions.
Multi-Ratio Current Transformers (Single-Core & Two-Core Options) for 25 kV max. Power Systems
CR-20S Series
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.
12 kV Two-Core Current Transformers
EWF-10D Series
2-core current transformers designed for 12 kV (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.
Overvoltage Protector for Current-Transformer Protection
CCTP-03
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.
