The precise's current transformers type COL are intended to be used, particularly, for transforming the high current of AC power systems to the lower current levels which subsequently are inputs for measuring systems.

The COL current transformers are fundamentally designed for up to 36 kV oil type outdoor installation, however for indoor sites where the equipment may expose to severe environmental conditions the COL are recommended
