20kV Multi-Ratio Current Transformers (Single-Core & Two-Core Options)


20kV Multi-Ratio Current Transformers (Single-Core & Two-Core Options)

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.

About the Product

Designed to be installed in a switchgear panel of a 25 kV (max.) power system, these current transformers can be used in conjunction with measuring or monitoring instruments, or with protective relays. The insulation material for the core and the secondary coil is Araldite® epoxy resin. The window-type design facilitates installation and wiring with a busbar or insulated cables, decreasing the occurrence rate of contact point failure. With excellent insulation and a high degree of moisture resistance, the CR-20S Series current transformers can perform in locations of high humidity or moderate pollution. These lightweight and economic CTs are quick and easy to install.

    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.
