Earth Electrode Solutions

Earthing – Single-family house with external lighting protection Whether existing or new buildings, a functioning earth-termination system is the prerequisite for the safe operation of electric systems in buildings and for protecting people from dangerous high voltages. The design and implementation of the earth-termination system are of central importance. When implementing the earthing concept, e.g. in the form of a foundation earth electrode, changes are no longer possible after the concrete has set. Omissions or errors during the construction phase cannot be corrected later or, at least, not without a great deal of effort and expense. Carrying out an earthing study is a mandatory requirement for every new installation project. The purpose of earthing in the electrical network is primarily to ensure safety. When all metallic parts of electrical equipment are grounded, there will be no effect due to dangerous voltages present within the equipment case, as earthing enables the discharge of the excess charges towards the ground. Although if there is a failure of insulation material inside the equipment, earthing prevents the building up of electrical charges on the equipment by discharging to the ground. Nexpo has built its in-house capabilities in performing thorough Earthing Study based on the latest standards IS 3043, IEEE 80, and more. From reliable soil resistivity surveys and calculations to being standard-compliant at all stages, we help ensure that the responsibility of the businesses and safety concerns for invaluable assets are met.

Dehn Terra
Earthing backfill for critical applications

DEHN Terra
Green backfill earthing compound.

WORLD’S FIRST FULGURITES FREE BACKFILL SOLUTION
Fulgurites free backfill material
Tested for lightning current
Complies with the standards IEC 62561-7 and IEEE Std 80.
Non leachable solution for flood prone areas
Maintenance free solution
Tested by TÜV Rheinland

DEHNterra is a fulgurites free, and green backfill earthing solution. The solution is critically synthesized to be compactable with a very good flow percentage value to ease out the installation of the earth pit. DEHNterra has been designed to increase the contact area between earth rod and inner wall of the earth pit.

High grade earthing solution

DEHN Terra is a versatile solution in order to provide the least resistance path for the short circuit and fault currents to the ground. It is a maintenance free green earthing solution which is soil-compacting to ease out the installation of the earth pits. This is a naturally inert solution for protecting the environment and increasing the lifetime of earth pit by having low and stable resistivity in the range of 0.02-0.12 Ωm, as required by the standards.

Low Ground Resistance

An important requirement for a perfect earth enhancement material is to maintain a low grounding resistance, with minimal fluctuation for a long period of time. DEHN Terra is a robust solution which is checked and found helpful in reducing and maintaining the earth resistance.
