1. HK series open type current transformers are designed in Paticular for convenient installation. Because of split core, you don't need open any cable or bus-bar when install.Â
2. The connection of ordinary current transformers need pause primary current to let cable and bus-bar pass through the core of current transformers. The core of HK series open type current transformers can easily be opened. Installation and connection can be available without cutting off the circuitry, so it can save time and installation cost.
3. Based on above features, open type current transformer has more advantages in adding CT after maintaining and circuitry.
