At our Bhushan Steel plant, we achieved remarkable results with Intertech’s Marconite transformer earthing system. Our earthing resistance improved considerably, and we have been able to maintain consistent 0.86 Ω resistance
Results:
The prestigious Panipat Refinery of Indian Oil Corporation Limited trusted Marconite technology for their electrical safety systems. Our earthing installation achieved 1.84Ω resistance in moderate soil conditions – far superior to conventional earthing methods.
Results:
Indraprastha Apollo Hospital in Sarita Vihar, New Delhi, chose Marconite earthing for their DG set installations. The system achieved an outstanding improvement in ground resistance, ensuring reliable power backup for life-critical medical equipment with 0.51Ω resistance values.
Results:
Unlike chemical earthing systems that require regular water and charcoal replenishment, Marconite transformer earthing system delivers consistent performance without any maintenance interventions.
Permanent low resistance of <1 Ωm is achievable that ensures your transformers are protected against earth faults, maintaining electrical safety standards across all industrial applications.
With the lowest lifecycle cost compared to chemical earthing, our transformer earthing resistance solutions deliver long-term savings while maintaining optimal grounding performance.
Our certified engineers conduct comprehensive soil resistivity testing and analyze your specific transformer earthing system requirements, including 11kV, 22Kv or 33kV earthing transformer specifications.
We design your transformer earthing resistance solution based on IEC 62561 standards, ensuring optimal performance for your specific transformer earth fault protection needs.
Our trained technicians install and commission your Marconite transformer earthing system, providing complete documentation and performance verification.

Marconite provides permanent, consistent low resistance of <1 Ωm is achievable, unlike chemical earthing that degrades over time and requires regular replenishment.
Typical installation for industrial transformer earthing systems takes 3-7 days depending on location and soil, including excavation, Marconite earthing placement, and commissioning with resistance testing.
Our Marconite systems consistently perform compared to conventional methods, with permanent earthign values of <1 Ωm for 50+ years.
Yes, our Marconite transformer earthing systems are fully compliant with IEC 62561 standards and suitable for all voltage levels including 33kV transformers.
We provide a 25 year performance guarantee on all transformer earthing installations, backed by comprehensive documentation and ongoing support. Although Marconite earthing can perform for 50+ years with stable earth resistance with almost zero maintenance.
If our Marconite transformer earthing system doesn’t meet the promised performance specifications within the first year, we’ll replace it at no cost to you.

As per our requirement and request, your company has provided the knowledge and installation of 5 nos. of maintenance free earthing stations based on Marconite (conductive concrete based earthing) at our Electron Beam Centre, Kharghar, Navi Mumbai. Out of these 5 earthing pits, 4 nos. are connected in the parallel network to achieve an earth pit resistance of 0.65Ω which is required for our HV pulse power applications. We are glad to get these maintenance free earthing stations having less than 1 ohm.

We adopted Marconite Conductive Concrete technology for treated earth pits 1 X 700 MW Ballary Thermal Power Project at Ballari of Karnataka Power Corporation Ltd. The land of the project is rocky terrain. The design was approved by our engineering group PEM – Noida and the client and could be able to achieve the desired earth resistance as per client’s requirement.
