The Socomecs core balance transformers are designed to be installed in the fault detection and locating units. The transformers surround the active conductors to highlight a faulty current to the earth. The Socomec core balance transformers meet measurement sensitivity needs and are suitable for ISOM Digiware locating systems. Solid (ΔIP, WR and TFR series) or split-core (∆IP-R series), they are suitable for all cabling configurations.
