Type KBCH relays offer biased differential current, restricted earth fault and overfluxing protection.
The user-friendly, three-phase units are compact in design and easy to install.
3-phase units require no interposing transformers
Used primarily to protect two or three winding power transformers, auto or generator-transformer units, KBCH type relays are very compact, thereby facilitating installation. Each model is a 3-phase unit with internal vector group compensation and line current transformer ratio correction. There is no need for interposing transformers.
Space efficient and user friendly
The KBCH relays benefit from compact multi-functional numerical keys and built-in interposing CT. Optimally designed for space-efficiency they also provide user-friendly interfacing. |
