Solkor Boxes

Wall mounted Solkor box

A ‘Solkor’ relay is the trade name of a well-known pilot wire current differential relay made by Siemens.

Acrastyle builds this device into a small self-contained wall box with all the associated scheme wiring, test facilities and backup protection commonly used in a standard scheme by some UK utilities.

These are also purchased by development contractors. An existing feeder with a Solkor pilot wire scheme applied is split in two and a new substation inserted in the middle of the feeder.
