DEI has extensive experience with high-voltage transmission system protection. Our products are used for safety grounding on pipe-type cable and lead sheath cable construction, replacing older technologies. DEI products allow copper concentric neutrals or sheaths to be galvanically isolated from lead sheath construction. Pipe-type cable with insulated joints in oil supply lines can be protected from AC faults and lightning. Power transformers can be protected from GIC and DC currents in the neutral grounding conductor using DEI decoupling devices. Assured safety grounding and greater reliability are the hallmarks of an electric transmission grid protected by DEI products.
