Earthing Transformer Manufacturer & Supplier in Nigeria

Urja Techniques (India) Pvt Ltd is a leading transformer manufacturer based in India, supplying a wide range of high quality transformers - including converter duty, power, distribution, furnace, earthing and dry type transformers - to clients across Nigeria. With a focus on energy efficiency and dependable after-sales support, we serve buyers in Lagos, Abuja, Port Harcourt, Kano, Ibadan and Aba.

Product Introduction:

An earthing transformer provides a neutral grounding path for three-phase systems that do not have one, protecting the system from damaging over-voltages and faults and improving overall grid safety and reliability.

It offers a path for fault current during a line-to-ground fault, limits the build-up of static charges and helps stabilise voltage. Designs include Zig-Zag, Wye-Delta and Wye-Wye to suit the application.

Features:

1. Strong safety features and dependable earth-fault performance.
2. Designed to withstand short-circuit conditions and carry fault current.
3. High mechanical strength, thermal resistance and excellent insulation.
4. Compact, durable and easily maintainable.

Advantages:

1. Provides a secure grounding point, reducing the risk of faults and over-voltages.
2. Improves the dependability and safety of power systems.
3. High thermal capacity and long service life for cost-effectiveness.

Applications in Nigeria:

● Neutral grounding for ungrounded three-phase systems
● Wind and solar farm system protection
● Substation and distribution network earthing
● Integration with Neutral Grounding Resistors / Reactors (NGR)
● Station-service grounding with auxiliary winding

Why Earthing Transformers are in Demand in Nigeria

Niger Delta oil & gas operations, the Dangote Refinery at Lekki, ongoing power-sector reform across the GenCos, DisCos and the TCN grid, and Rural Electrification Agency solar mini-grid roll-outs are driving new transformer demand. Each project needs reliable transformers engineered for local conditions. Note that the Nigeria grid operates at 50 Hz, so our units are custom designed for 50 Hz or 60 Hz operation to match local utility and project specifications.

Supply & Logistics Across Nigeria

We export earthing transformers from India to all major Nigerian industrial and port regions. Consignments are shipped through Apapa and Tin Can Island ports in Lagos, Onne Port near Port Harcourt and Calabar Port. From there we serve the Lagos industrial belts of Ikeja, Apapa and Agbara, the Lekki Free Zone, the Ogun industrial corridor, Port Harcourt, Kano and Aba, covering the oil & gas, manufacturing, cement, power and utilities, mining and agro-processing sectors.
